Factors Influencing Screw Conveyor Design

Screw conveyors can be designed with non-sparking materials to eliminate a possible ignition source. Pressure tight troughs or housings with mechanical shaft seals will keep oxygen from entering the screw conveyor. The inside of the screw conveyor trough or housing can be purged with an inert gas such as nitrogen. Explosion venting is also an option for relieving pressure due to an explosion.

Screw Conveyor Manufacturers Screw

Screw conveyors, also known as auger conveyors or industrial screw conveyors, are systems designed to transfer free-flowing and non-free-flowing, dry and semi-dry bulk materials. Note: Since the operation of the system involves a screw cutting through the bulk materials, we do not recommend using screw conveyors to process substances that are sticky or do not break down easily, such as gels.
