Twin shaftless screw conveyors are made up of drive device, head section,many middle section and tail section .Except the head section and tail section, the standard screw flight and screw trough can be replaced . Set up the cleaning device at the discharge outlet.The inside lining plate is made of nylon or UPE /Ultra-high molecular Weight Polyethylene.
Many powder,small granules will be blocking and bridging inside the silo ,which can not discharge materials sucessfully. Wuxi Changrong’s conveying machinery company ‘s twin shaftless screw conveyor with broken arch silo can solve the bridging problems ,materials will be discharged smoothly as conveyors running. The broken arch silo’s bottom is twin shaftless screw conveyors which can transport and discharge materials out evenly.

Twin shaftless screw conveyor with broken arch silo are used to transport filter cake ,the filter cake’s bulk density is 500-600kg/m3,conveying capacity of conveyor is 12.8m3/hour.
Twin Shaftless Screw Conveyors’Fabrication Process
Each process is under strict checking and we have checking records .Twin shaftless screw flight is continuous welding with reliable quality.
Manufacturing Process on making a set of shaftless screw conveyor.
Before we used traditional way to cut materials which needs much time to finish the cutting.Now we use laser cutting machine to cut raw materials.
