No central axis interference, for the conveyor belt, easy winding material has special advantages. Shaftless screw conveyor uses: xLS series of shaftless screw conveyors are used in sewage treatment plant conveyor fine grid grid spacing 50mm decontamination grid residue and filter press mud and other materials. Good environmental performance. With fully enclosed transmission and easy cleaning screw surfaces to ensure sanitation and the sent materials are not affected by pollution, do not leak. Large torque, low energy consumption. Helical shaft, the material is not easy to plug and discharge opening is not blocked, and thus at lower speed, smooth transmission, reducing energy consumption. Torque of up to 4000N/m. Transport capacity. Throughput is the same diameter 1.5 times of the traditional axis spiral conveyor. Long distance transportation. Stand-alone transport up to 60 metres in length. And according to user needs, multistage in-line installation, long distance transportation of materials. Mobile work, use of a machine. Below the discharge, and head out. Using a special liner, this machine can work at high temperatures. Compact, space-saving, pleasing, easy, economical and durable.
