 LS  Series double shafted screw conveyor or twin shafted screw conveyor is  application in continuous transporting for powder,granule,and small bulk  materials.Unsuitable for deterioration ,sticky or glutinous and lumpish  materials. It is widely used in metallurgy,chemical,building plant and steel  factories . 

Consist  of
 Shafted  screw conveyor is mainly consisted of three parts :

  2. feeding point and discharging point .

  3. screw body: including head & tail bearing,screw flight,trough  body,cover,support frame,etc

How  does screw conveyor work
 As the  fixed center shaft with screw flight rotate in the trough, materials which fall  into the trough rotate with screw flights.During running,both materials and screw  flights are held back by friction resistance acted on the wall of trough .Then  screw flight push materials and make materials do axial  movement.Finally,materials will be discharged at the proper discharging point  at the bottom of trough or discharged at the end of trough.

 Simple  construction
 Feeding  and discharging points can be multiple positions
 Easy to  operate
 Good  sealing
 Friendly  environmental conveyors


  1. U shape  ,easy for clean and maintain

  2. Low speed  is good for transporting sludge

  3. Carbon  steel structure and withstand corrosive painting .Much cheaper than stainless  steel .
