Technical introduction

Application range:
WLS type shafless screw conveyor is widely used, suitable for horizontal conveying, inclined conveying, short distance conveying and long distance conveying, and can be matched weighing system.
It is especially suitable for sludge transportation before and after dehydration.

Advantages

Performance and characteristics:
1. Simple structure, no shaft in conveyer trough; smoothly conveying of materials;
2. The whole conveying process is carried out in closed conveying trough; no material overflowing; preventing secondary pollution;
3. Shaftless screw adopts specical processing technic. The molding length once is longer tha n2.5 meters.
4. Run slowly; less noise; less energy consumption; no need for maintenance;

Working principle

Installation form:
Standard form: fixed level installation or tilting installation; it also can adopt hanging type, mixing type of fixed type and tilting type, mobile type (can rotate around axis of feed inlet) and other installation types according to customer’s request; 
Model description: 
Shaftless screw conveyor
Model description Structure and working principle:
WLS shaftless screw conveyer is mainly composed of driving device, shaftless screw, U-shaped slot, liner panel, cover plate and feed hopper. Working principle: materials are sent to conveyer from feed hopper. Then, materials are driven to discharge outlet by rotary shaftless screw.
