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.
