GRIZZLY screens - Screening, classifying, dewatering

AViTEQ-Vibrating GRIZZLY screens are characterized by great robustness and durability. They serve as a discharge unit with an integrated screening function below the silo or bunker discharge, as feed units upstream of crushers, conveyor belts, screening, or for loading or simple screening. Depending on the task, the units are protected with wear plates at the inlet section and have two or three bar grate levels. Each bar grate insert is tapered in the conveying direction. This increases the gap, and prevents the bulk materials from becoming wedged Grizzly screens from AViTEQ are characterized by great robustness and durability.

Advantages & benefits

Wide range of applications:

• product to feed
• screening of gross grain
• separation of gross grain before classifying
• separation of fine grain from crushers
• protection screening in front of conveyor belts

Construction

The main components are:

• conveyor with drive traverse
• bar grate inserts
• drive (unbalance motor / exciter)
• elastically support

Selection

The sizing depends on:

• conveyed material
• throughput
• separator size
• required geometry
• possible installation

Key figures
