And it has wide application in several fields.

The screw conveyors are compact and easily adapted to congested locations which can be used as a mixer or agitator, to mix and blend dry or wet ingredients. Screw conveyors are available in a wide variety of materials to resist corrosion, abrasion or heat.

When it comes to screw conveyor, there are two things for specialized workers to grasp. They are correct operation and daily maintenance work. The following tips will give you the right guide.

1. Tips on how to control it correctly
