Application
U Type Trough Shaftless Screw Conveyor is widely used in building materials, metallurgy, chemical, electric power, coal, machinery, light industry, grain and food industry, suitable for conveying powder, granular, small pieces of materials, such as cement, coal, grain, chemical fertilizer, ash, sand, coke, etc. should not be easily perishable, viscous, easy to agglomerate the material. Commonly seen in the food industry, these conveyors transport ingredients to and from mixers, ovens and vats and need to be sterile at all times. Therefore, they are commonly made of stainless steel, a smooth food grade metal that is less likely to contaminate edible ingredients than other materials and is easily cleaned.

Working Principle
U Type Trough Shaftless Screw Conveyor is rotating spiral blade for screw conveyor conveying the material goes on, the material is not spinning force with the blades of screw conveyor is its own weight and screw conveyor casing material for material friction screw conveyor on the axis of rotation of the welding of spiral blade, blade surface type according to the conveying material have different entity type belt type surface type, such as type of screw conveyor screw axis of vane surface terminal at the direction of material movement have thrust bearings to the material to spiral axial reaction force, when the captain a long, should add hanging bearing in the middle.
