Screw conveyors are easily adapted to congested locations, due to their compact and flexible design; enabling horizontal, inclined and vertical installations.

Screw conveyors are used for dust and odor free transport of numerous materials such as dewatered sludge, pulp, wood chips, sawdust, chemicals, slaughter-house refuse, garbage, scrap metal, pellet fuel etc. The conveyors are particularly suited for transporting materials which tend to jam, material containing particles of varied sizes which often tend to form “bridges”, hygienic material, and material of a sticky nature. Since it is possible to feed directly into the side of a second conveyor and even transport vertically, compact, space-saving installations are possible. 

Working Principles 

The material has to be transported enters the conveyor through the inlet into the U-trough. The drive unit rotates the spiral, usually at a relatively slow speed, transporting the material to the outlet. The replaceable wear liner protects the trough and assures smooth, quiet operation. The motor mounting flange allows for safe and easy service. The cover is bolted to the trough for easy removal and can be fitted with inspection lids. 


-Tailor made design.
-Carton steel, stainless steel or abrasion resistant steel are available.
-"U" shaped or to provide a wider opening "V" shaped trough can be manufactured.
-Engineered to handle fine or coarse, granular or flaky, wet or dry, pellet or slurry materials.
-Fully enclosed trough ensures dust-free environmentally friend operation.
-"Live bottom" applications for silos and bunkers
