Application of Industrial Screw Conveyor

The operation of industrial screw conveyor involves the rotation of the screw, which moves the material along the trough. As the screw rotates, the material is pushed forward or upward depending on the design and orientation of the conveyor. The helical flighting acts as a continuous spiral that creates a positive displacement, effectively moving the material in a controlled manner.

1.Agriculture and food processing: Screw conveyors are used to transport grain, feed and granular agricultural products. They can transport grain from storage warehouses or unloading areas to processing equipment or packaging lines.

2.Chemical and pharmaceutical: Screw conveyors are used to transport powders, granules and granular chemicals or pharmaceuticals. They can transport raw materials to reactors, mixers, dryers or packaging equipment during the production process.

3.Food processing and packaging: Screw conveyors are widely used in the food processing and packaging industries. They can be used to convey materials such as flour, powdered sugar, spices, vegetables and fruits.

4.Construction and material handling: Screw conveyors can be used for material transportation in construction sites and material handling facilities. They can transport materials such as concrete, sand, gravel, cement, etc. from one location to another.

5.Water treatment and waste treatment: Screw conveyors play an important role in sewage treatment plants and waste treatment facilities. They can be used to transport materials such as sludge, solid waste, sewage treatment residues, etc.

6.Waste Disposal and Recycling: Screw conveyors are used for waste handling in waste disposal and recycling facilities. They can transport waste from sorting tables to compactors, incinerators or recycling equipment.
