Limestone is to be dischrged from a bunker. The trough conveyor must be fitted into the existing installation space so that the replacement of spare parts and maintenance can be carried out easily and safely.

The delivered hopper discharge conveyor of the type OAO 1500/1000-UVG38X+AB has been designed for the installation conditions at the customer's site. A flow sensor is integrated in the discharge conveyor, which indicates the fill level (empty or full) of the discharge chute via an inductive sensor. In addition, a pipe for flushing is integrated in the rear wall of the hopper outlet.

The customer received a solution that allows continuous discharging from the bunker and optimal access for maintenance. The space situation was optimally used by fixing the unit to the bunker (no additional support frames).

Different shredded plastic materials are to be distributed across the screen width. Different screen linings must be used, which can be changed quickly and easily as required. The stability of the unit was also a customer request.

The VSB 980/2500-UVG21W screen supplied has been individually adapted to the customer's application and installation conditions. The screen tension is selected in such a way that the individual screen linings can be changed quickly and easily. Guide plates are fitted in the inlet area to ensure that the material is evenly distributed across the entire width.

The customer received a solution that enables uniform distribution as well as screening. The secure installation by means of swinging elements on the frame has also been realised.

Rock salt is to be separated underground. For this purpose, the main product stream is pre-classified after the first crushing stage (roller crusher) by means of a bar grate. In terms of the separation plant, this partial stream contains both coarse material and fine material, which are to be separated by a screen. The coarse material and the fine material are returned to the main product tower above ground. The medium material is fed to the separation plant for the separation of rock salt. The task is to supply a suitable screening machine that separates the feed stream into the above fractions. One of the most important boundary conditions is the limited installation height that has to be observed underground.Rock salt is to be separated underground

The unit was designed as a fine screen (type VSF1840/5600ASS-UVP119W) with changeable screen inserts. The first screen deck is used to screen the coarse material larger than 3.0 mm and the lower screen deck is used to screen the fraction < 1.0 mm. The screen construction was designed with a frame construction in which the screen inserts are fixed in place and with a cover above. The complete frames are braced together by means of threaded rods.

Screening of fine material

Limestone is to be extracted from a bunker (60 tonnes) and then fed onto a belt conveyor. For maintenance purposes, a shut-off device is to be provided and a protective screen is also to sieve off the fine fraction. 

The supplied bunker discharge conveyor with a length of 2200mm and a width of 800mm (type OA2200/800ASS-UVG21W + AB +FN) is exactly aligned to the installation conditions at the customer's site. The needle valve serves as a shut-off device. The conveyor trough is provided with a screening area at the outlet.

The customer has received a robust solution that meets the discharge from the bunker as well as reducing the fines fraction of the limestone.

Animal feed has to be extracted from a bunker.  The fine fraction has to be reduced by conveying/screening.

The vibrating feeder of the type OA 1950/500-MVES50-1 are adapted to the installation conditions at the customer's site. A screening zone is integrated in the bottom of the conveyor trough, which reduces the fine material by means of protective screening. For hygienic reasons, the feed chute is equipped with a cover and the inlet and outlet connections are sealed with sealing sleeves.

This solution offers a continuous discharge from the bunker as well as a simultaneous reduction of the fine fraction within optimum utilisation of the space situation.

From the steelproduction industry came an inquiry about the discharge of DRI (directly reduced iron). This manufactured material is an essential component within steel production. The customer discharges the material directly from the bunker with a conveyor belt. Since the material is highly abrasive, the conveyor belt must be replaced regularly. In addition, the customer wants to weigh the product in order to feed the DRI accurately to the next process steps. Translated with www.DeepL.com/Translator (free version)

AViTEQ offered a combination of a weighfeeder and a vibratory feeder with magnetic vibrator. The vibratory feeder is used to close the hopper and as a discharge device to gently discharge the DRI and feed it to the downstream weigh feeder. The weigh feeder measures the throughput via weighing cells and, in conjunction with the vibratory feeder, regulates the amount of DRI required.

The vibratory feeder can be used to discharge the highly abrasive DRI from the bunker. The vibratory feeder gently transfers the material to the conveyor belt without exerting additional pressure through the material. In this combination, the conveyor belt can be significantly spared and only needs to be replaced very rarely. The magnetic vibrator of the vibratory feeder is maintenance-free. This means that there are no further follow-up costs. The weighfeeder weighs the product with a high degree of accuracy.

A tipping device is used for loading a galvanising barrel. The operator pours the raw material into the chute of the tipping device. By means of a scale on the device, the operator knows how much he has to put into the chute. The loading system is to be automated in a more user-friendly way as part of a conversion project. The raw material is to be discharged directly from the crate used into a material hopper located above the oscillating conveyor chute. When the required weight of the material is reached, a flap is to close the system.

AViTEQ offers a solution with a vibrating discharge unit (OA1500/500ASK-MVD). This consists of a hopper above the vibrating feeder that pulls the product out of the hopper and a pneumatic flap system. The flap, which is rotatably mounted on the chute, opens the conveyor chute via pneumatic cylinders and moves a chute to the end of the vibrating feeder. The vibrating conveyor chute then feeds the product from the hopper into the chute, which directs the product into the drum. When the entered target weight is reached, the flap closes. The surfaces that the screws touch are additionally protected with a sprayed-on polyurethane. In addition to wear protection, this also minimises noise.

The discharge unit minimises the working time of the person filling the system. The operator no longer has to weigh manually the correct quantity on site. The system is only filled and then independently regulates which quantity is fed into the galvanising drum. By using the magnetic vibrator drive, there are no further follow-up costs due to wear. This drive can be used for decades without maintenance and relubrication.

A battery recycling process processes 20 tons of batteries per hour. After the batteries have been separated and crushed in a centrifuge and crusher, the elements obtained in this way, such as plumb, must be fed into a furnace.

For this purpose, AViTEQ produces a vibrating feeder with a total length of 7.5 meters (OA7500 / 800-UVP85V). The vibrations allow the plumb elements to be conveyed cleanly into an oven. In the discharge area of the channel into the furnace, a screw-on "nose" made of highly heat-resistant stainless steel was attached, which protrudes into the furnace. A frequency converter was also installed.

With the help of the frequency control, the product can be partially dosed into the oven. In doing so, the necessary transport length of 7.5 meters is overcome. The specially designed outlet area in the furnace withstands the very high temperatures inside and can be renewed without having to rebuild the ccomplete feeder.

The customer stated that drilling fluid has to be separated from the drilling mud of earth boreholes due to legal regulations. A dewatering screen is required for this, which should be planned horizontally, but it can also be set to a slope using an on-site tilting device. The screen linings were provided by customers.

The customer received a dewatering screen type VSW640 / 2750-UVF24X for separating the drilling fluid from the drilling mud with a trough width of 640mm and a trough length of 2750mm driven by two unbalance motors. The screen linings are made of polyurethane and steel mesh are designed as

With the dewatering screen, the customer receives a very important component for his separation & recycling machine for drilling fluids from the HDD drilling process. Thanks to the screen, the on-site water cycle is not unnecessarily burdened and the drilling fluid can also be recycled directly. Thus, the legal regulations and the requirement for recycling and sustainability and economy are fully met.

The product has to be discharged from a bunker and all fine parts have to be separated from the coarse grain for the further process. Very good sealing and economical cleaning intervals were further basic requirements for the screening. The loading of a multi-head weigher also requires the possibility of a quick start/stop for the  conveying process.

The customer received a guided arm vibrating screen type OLR 500 / 2500-2MV421 / 16 with a width of 500 mm and a length of 2500 mm with magnetic drive and frequency controlled. Due to the high standards QS2.1 in the food industry, the trough and the cover were made of stainless steel 1.4571 polished electrochemically. The screen linings were installed in a trough-shaped construction for sealing reasons and balls ensure constant cleaning. Ergonomic quick-release fasteners the long cleaning intervals have also been installed.

The vibrating screen has a very low energy consumption, is very quiet and there is a very gentle conveyance with a compact and flat design. The well-sealed screen results in a fairly pure product. The wide range of conveying capacity as well as the quick start/stop activation bring the necessary flexibility in the production process.

The customer receives additional products for the dog food production. These 25kg containers are delivered from suppliers from all over the world. For quality reasons, the bags should be subjected to a protective screening in order to be able to screen out any foreign objects (such as fishing nets, metal parts, etc.). The linear feeder screen should also be movable for production reasons.

A compact feeder type KF12 was supplied as a screen with a trough with a length of 1200mm and a width of 300mm. The trough is made of V2A (1.4301) electrochemically polished and has perforated plates in the floor of the outlet area. The hole diameter is approx. 3-5 mm and the trough is designed with a free outlet for oversize particles. The bunker is also made of V2A (1.4301) and electrochemically polished with a slide gate for layer height adjustment and with a movable frame.

The customer achieves the desired quality standard with the supplied Compact feeder with screening function for his additives. The mobility due to the movability of the dosing screen gives the customer an additional flexibility in his production process.

Rock is delivered by truck into bunker. An extraction machine then takes care of the transport from the bunker to the crusher. During the feeding process to the crusher, the undersize and medium grain should be screened out so that only the oversize is fed to the crusher. At this point, the use of a Vibrating GRIZZLY screen is necessary.

A Vibrating GRIZZLY screen with a width of 1800mm and a length of 4750mm was installed between the extraction machine and crusher, which is driven by an unbalance exciter. A rubber coating in the inlet area of the screen trough provides the necessary impact protection. Subsequently, the rod grate screen ensures the desired separation of the undersize and medium grain from the oversize, so that only the oversize is transferred to the crusher in the discharge area. Undersize and medium grain are fed back into the process on a belt conveyor after the crusher.

The central point here is the profitability around the crusher. On the one hand, it uses less energy when undersize and medium grain do not have to be processed in the crusher process at all, it protects the crusher in its workload and on the other hand there is also a time saving.

Granulated crunchy cereals should be conveyed upwards in the production process and at the same time cooled in such a way that it can be packed at the right temperature in the big bags at the end. Two tasks, one solution...       

The best solution for this task is our cooling spiral elevator type WFW6170 / 1200, which transports the cereals carefully up to an outlet height of 7.7 m while cooling down the still hot product. It is driven by two very large unbalance motors type UVP119W. All parts are made in V2A (1.4301). The surfaces of the spirals have been blasted using a special procedure. The ViwateQ® process meets the requirements of the food industry and produces high-polished surfaces. The surfaces of all other parts are pickled and passivated.

The advantage of that the spiral elevator is the soft product handling while cooling down at the same time. Each individual spiral base can also be cooled separately, which enables a very fine temperature control. The use of the cooling spiral feeder is efficiant within the cost in the production process and also regarding the substainability.

Peeled shrimps have to be fed to a sorter in a monolayer.  

There is a guided arm natural frequency conveyor type OLR1200 / 2000 with two stainless steel motors used. The trough is executed in V4A (1.4541) with structural surface. In the inlet area of the trough are some distribution plates for spreading the layer.

The shrimps are fed at the inlet area with a width of only 400 mm, so that they are partly in a multi layer position. In addition to the primary task of continuous feeding to the sorter at a width of 1200 mm, the secondary task was to obtain a monolayer at the transfer point. Both tasks could be fulfilled with the executed feeder and thus an optimal supply to the sorter.

For separation of castings  

A KF12x2 / 1300/500/360 with twin-drive with the connecting controller SRA-C50 / 01-1-1 was individually designed for the customer and manufactured according to the installation conditions.

Two KF12 small conveyor drives are placed side by side to provide the necessary flow rate for this individual trough. The executed trough is made of stainless steel 1.4301 and is electrochemically polished. The conveyor cross-section is rectangular. The design is open with a free outlet to the front, so that an optimal introduction into the production process can take place. In the inlet area is a baffle, which should solve the parts from each other. The middle part is designed with multi-track U-profiles and is limited by baffles.

Flowable and free-flowing silicon granules must be conveyed within an ATEX-Zone 22 area. In this case, the material should be fed via a feed bunker with layer height adjustment and foreign body protection on the hopper inlet. The material is metered from the closed system into the production process. 

The customer has purchased a small tube feeder that is driven by a magnetic drive, type eKF6 / 630 / D114-T50, which is certified to be operated in the ATEX Zone 22. The bunker is not closed and has foreign body protection for safety reasons. The round outlet is sealed by a cuff and that results to a full closed system.

The tube feeder of an explosion-proof design with a bunker in stainless steel design was chosen to suit the specific installation situation and executed as a closed system. This also fulfills all requirements of the ATEX Zone 22. The bunker acts as a buffer and thus enables a continuous dosing into the production process.

Shredded scrap metal is placed with a front end loader into a bunker. The bunker has to be fed continuously by weighing to an existing belt. The bunker stands in an acceptance hall and the very abrasive scrap metal is then further processed inside the hall. Therefore, there was a requirement to avoid dust as much as possible.

The parameters of the delivered feeder OA 4600 / 700ASS-MVG33-1P are designed exactly to the customer’s requirements. The capacity of the bunker was given as 5.8 m³. The material, which is in contact with the product has to be non-metallic because of the magnetic properties of the scrap metal. An installed water spraying system prevents the formation of dust. The simultaneous weighing is also installed for a continuous filling of the bunker.

The customer has received a complete solution that enables continuous filling of the bunker by weighing, minimizes dust formation and, thanks to the robust design, also meets the requirements of the abrasive bulk material. The unit was designed to use the best use of the space available.

In a vacuum conveyor for candies the discharge area has to be empty every 3 to 4 minutes. Here, in the case of round candies, 1 to 2 kg of chewy candy pieces (punch residues) are deposited per emptying, which are dosed uniformly into a mixing screw until the next emptying of the vacuum conveyor and thus are to be returned to the production process.

The customer has received a tubular conveyor with magnetic drive and hopper type KF1 / 100 / D101-T (S). The hopper has a cover to provide a closed system.

The tube feeder with hopper in stainless steel design was adapted exactly to the situation installed and executed as a closed system for fulfilling all requirements of the food industry. The hopper serves as a buffer for different flow rates and for continuous dosing to the mixing screw.

The customer required a new transport system solution for his material infeed within his steel plant, as part of this project the customer required a new bunker discharge conveyor. The bunker was located outside and was fed by a bucket unloader. The first priority was that the discharge of the material should not disturb the construction of the bunker or the flow of material. A reconstruction of the existing bunker system was to be avoided. Therefore the conveyors had to be designed for the specific application.

Two trough conveyors type OA with the length of 3,500 mm and the width of 2,000 mm.

Due to the high flow rate, the customer received two trough conveyors. They would be positioned parallel to the existing conveyor belt. The installation of each trough conveyor was inclined 12 °. Also due to the high flow rate, unbalance exciter’s were the best solution. The final solution meant that no reconstruction of the existing bunker system were required.

A French handling company has designed and built a complete granite processing plant for his end customer based in the France. Within the processing plant, the granite stones have to be drained of excess water at various points. For this they sought an efficient solution. It was important that the screen media can be changed, so to reduce downtime.

The granite stone material is generally greater than 2 mm grain size. This is the perfect situation for the AViTEQ dewatering Screens, which is developed for granulates. They offer the advantage that they can be constructed more easily compared to conventional dewatering screens for sand. As a result, small unbalanced motors can achieve very good performance and also dewatering results. The total of 6 dewatering screens are driven by robust AViTEQ unbalanced motors, which are specially designed for longevity and difficult conditions. The outlet area is protected against wear with Hardox 400 liner plates. The screen decks consists of polyurethane screen media with a mesh width of 4mm x 23mm, which are arranged transversely to the conveying direction. A special easy change system has been installed, which allows a quick and easy change of screen decks. In addition, the complete dewatering screen are completely galvanized. So to reduce corrosion through their service life.

Through the use of the AViTEQ dewatering screens, the plant builder was able to offer his end customer a dewatering solution that corresponds to his expectations regarding the desired moisture value. The special screen system was also able to meet the requirements of a quick screen deck change. This is complemented by the AViTEQ unbalance motors, which is a perfect investment in the longevity of the plant.

Within a production process for Calcite, the coarse-grained bulk material is crushed by a mill with grinding balls. The grinding balls crush the calcite into a very fine proportion (95% <30μ) and in a fraction with broken pieces. The friction of the grinding balls in the mill results in a temperature of 110 ° C in the product mixture. The combination of a high fine content and temperature leads to the fine content adhering to the grinding balls. The customer is now looking for a solution for the following problem. On the one hand, he wants to free the grinding balls from the fine portion and return them back to the mill, since manual cleaning is time-consuming and cost-intensive. He would like to classify the fine part of the fragments. The fine part represents the finished product. The fraction with the broken pieces are useless for further use in the grain size. For this reason, the fragment should be returned to the grinding process in order to reach the correct grain size.

AViTEQ proposed to the customer a linear vibrating screen driven by unbalanced motors (VSB1500 / 3000-2UVK79W). The screen has 2 fine screen decks made of long-life thin-wire with large open screen area. The upper screen deck has a long mesh of 2 x 6 mm and the lower one a square mesh of 1x1 mm. Two difficulties with respect to the screen had to be solved constructively. The first thing to mention is that the bulk material mixture has a temperature of 110 ° C. As a result of the introduction of heat into the screen decks, a length expansion occurs and the screen deck is in danger of "fluttering" and thereby causing damage to the screen media. Due to an intelligent spring tension, the screen decks does not lose its tension even in the case of a longitudinal expansion. The fine proportion of the calcite (97%

<30μ) is the second problem. The fine proportion in the bulk material mixture tends to blind and block the screen decks and, in conjunction with temperature, also lead to adhesion (caking) to the screen body. Vibration is the ideal solution for this problem. A high acceleration of the screen basket and the screen decks of 4.5 G and a vibration (swinging width) of 8.2 mm at a frequency of 16 2/3 Hz will remove the fine portion from the screen. In order to prevent "caking" in the bottom area of the sieve, the floor was made of highly polished, polished stainless steel (IIIC). The screen is rounded with temperature-resistant sleeves (up to 200 ° C) in the inlet and outlet area.

The AViTEQ linear tensioning screen can reduce costs and time for the customer. Manual cleaning of the balls in no longer necessary. In addition, thebroken pieces can be returned to the process. This results in less waste product.

TPE granules are thermoplatic elastomers and do not consist of rubber (rubberu), what means that they behave like conventional elastomers, but can be plastically deformed with heat supply what results in a thermoplastic behavior. Within the production process, the hot granules must be cooled down in the core. In addition, the product must overcome a height difference of 4 meters. 

An AViTEQ spiral conveyor is ideally suited for this task. AViTEQ sold a WF4000 / 890-UVH38W spiral conveyor with double-walled bottoms. According to the invention, the helical conveyor is designed as a cooling conveyor. In this case, the double bottoms are connected in series with rubber hoses and connected to an inlet and outlet system. The helical conveyor has a height of 5630 mm and a winding speed of 890 mm and is made of V2A. The ViwateQ® process has been applied to optimize the surface finish.

The spiral conveyor is feeding up the product up only within lifting movements as result of the vibration. The TPE granulate is located in the air at 2/3 of the time and can therefore be conveyed upwards in a very sensible. Through the double floors, cold water can be conveyed into the product-contacting floor. This allows the product to be ideally cooled down from its original temperature to a temperature range in which no more deformation takes place.

Lime is used in many ways. In the extraction of iron, lime makes the ore lumpy and highly porous. In the blast furnace, lime is used for binding liquid pig iron from interfering mineral impurities. Regarding this process, the customer needs some trough conveyors to transport the material out of the bunker. The limestone contains a humidity of 3-12%.This leads to adhesions and a blocking of the trough conveyor. This reduces the conveying capacity of the feeder.

AViTEQ supplied vibrating conveyor with a length of 2070mm and a width of 1300mm (OA2070 / 1300ASC-MVG33-1). The vibration conveyor are excited by a powerful and compact AViTEQ magnetic vibrator. The vibrating conveyor tough were delivered with a ceramic lining and round corners (140mm radius). In order to detect malfunctions at an early stage, a vibration sensor was also installed.

The lining used by AViTEQ helps to reduce caking and also to reduce wear and tear for the customer. The design optimized trough with rounded edges also minimizes the risk that the material can get stuck in any corner. The sensor can detect any malfunctions of the vibrating conveyor at an early stage. The AViTEQ magnet vibrator offers an optimum acceleration for the bulk material and can be adjusted continuously from 0% -100% so that the material can be dosed ideally.

Weighing and charging different bulk materials, like raw meal, cement and broken slag, while adhering to the special customer requirements for the installation situation and the operation / weighing process. It was important, that the system is closed.

The product should be screened into two fractions, a fraction of 0-0.3 mm and the second fraction 0.3 - 12 mm.

The device was designed as a micro sieve with changeable screen decks. The coarse material is larger than 2.5 mm with the first screen deck, the grain size <0.6 mm with the middle screen deck, and the fraction <0.3 mm with the lower screen deck. The screen construction was carried out by a frame construction in which the screen decks are inserted and fixed by the overlying frame or the cover. The complete frames are tensioned with each other by means of threaded rods.

During the steel production lime is used in different places. For example, lime is used in steel heaters for separating pig iron and crude steel from interfering components. In addition to different hopper discharge units with unbalance motors and magnetic vibrators, the customer needs a linear vibrating screen for classifying the lime into three fractions. The separation cut should be> 50mm, between 10 and 50 mm and <10 mm. The temperature range in steelworks are between -38 to + 39 ° C.

AViTEQ chose a linear vibration screen with unbalance motors (VSBO 1600/6000 - ASS - 2UVP119W) as the best solution. The screen has a length of 6000 mm and a width of 1600 mm. As screen insert were used Longitudinal tensioner, which can be quickly removed. The screen holes are long meshes and the material of the screen cover consists of spring steel. The screen is driven by two 6-pole unbalance motors with a speed of 1,000 rpm (corresponds to a vibration frequency of 16.67 Hz). Additional linings made of Hardox 450 help against wear. In order to keep the dust load low, the screen has a dedusting flange for classifiying the dust particles. A special aluminum plate was also used for the inspection covers, which is characterized by its lightness and stability.

By means of the screen, the customer achieves the desired screen quality and can use the limestone optimally in his process. The screen is designed for longevity and temperature fluctuations. The dedusting prevents dust from spreading in the production environment and the special aluminum honeycomb plate allows for a very easy removal of the inspection cover without loss of sensitivity.

The forging sticks should be feeded into a hardening furnace. The cycle time should be 6 sec./ pcs. In the production plant, the default 80 DB volume does not exceed.
