          LS screw conveyer

           

             LS screw conveyer is optimized and designed through learning from foreign advanced technologies by the scientific research personnel of our company. The conveyor is a mechanical product which uses the motor through the reduction gears to put the helix in motion so as to drive the materials, realizing the conveyance. Such merits are available as simple structure, small area occupation, long (high) distance of conveyance, closed conveyance, multipoint material feeding or unloading. It can convey all types of powders, granules or small bulk cargos in a horizontal, tilting or vertical direction. It is an ideal piece of conveying equipment for the industries as follows: chemical, medicine, agricultural chemical, fertilizer, dyestuff, metallurgy, mining, salt, concrete admixture, plastics, building material, food and feed.
