Simple structure,reliable operation, low noise machine,wide use,fully enclosed design,no secondary pollution;robust SS304 body Shaftless Screw Conveyor1: Product introduction  Model WS-LS Shaftless screw conveyor with advanced technology, novel structure, is an ideal alternative to the shaft screw conveyor, belt conveyor and one of the main equipment of the sludge dewatering system.WS-LS shaftless screw convoyer is widely used for various industries,such as waste water treatment, building materials, electricity, chemical industry, metallurgy, coal, machinery, light industry, grain and food industry.Advantages as below: Simple structure, reliable operation, low noise machine, wide use, easy to maintain, flexible layout; shaftless screw conveyor make solid cake transportation move smoothly; fully emclosed design, no secondary pollution; shaftless screw conveyor  using a special molding process, high rigidity;screw groove material: SS304( or anticorrossive carton steel); spiral body:SS304( or alloy);groove gasket material: high rigid nylon. 2:Working Principle  WS-LS type shaftless screw conveyor consisits of drive equipment, shaftless spiral body, U-shaped groove, inlet and outlet mouth, cover and stand. When the material goes into the U-shaped groove, the use of friction between the spiral shaft and material can force the material go into th outlet mouth to discharge. 3:Working Condition   WS-LS type shaftless screw conveyor request on the transport of materials: this machine should not transport perishable, viscous, easy caking materials, suitable for granular powder and small caking materials such as dehydrated sludge, coal,food, fertilizer, ashes, sand, and so on. The working environment should be between -10 °C ~ 50 °C, the material temperature shall not exceed 100 °C. Allows tilt, the maximum angle should be not more than 30 degrees. 4: Model description  WS: Weishi code  LS: shaftless screw convoyor machine  O: spiral body diameter 5: Technical Data:

Screw Space(mm)	260	280	300	320	340	360	380	400
Speed(r/min)	19	19	19	19	19	19	19	19
Transport Capacity(m3/h)	4.6	4.6	5.6	6.6	7.6	8.6	9.8	11
Power(kw)	2.2	2.2	2.2	2.2	2.2	2.2	2.2	2.2

Note:1:Screw speed(deviation within 10% allowed)          2:Transport Capacity is horizontal level transportation.          3:If the conveyor is inclined to tilt,the transport capacity should consider the impact of tilt coefficient, tilt coefficient horizontal level is 1,tilted 10 degree is 0.8,tilted 20 degree is 0.65,tilted 30 degree to 0.5.For example: conveyor horizontal transport capacity is 6.6 m3, the throughput for 6.6*0.65=4.3m3, if tilted to 20 degree.
