Trough screw conveyor with a fully enclosed transport and easy to clean surface of the spiral, to ensure sanitation and send materials free from contamination, do not leak. Torque, low energy consumption. Spiral shaftless, the material is not easy to plug the discharge opening is not blocked, and thus lower speed operation, smooth transmission, reducing energy consumption. Torque up to 4000N / m. Conveying capacity. The throughput is 1.5 times of the tradition of the same diameter shaft screw conveyor. Transmission distance is long. The stand-alone transportation of up to 60 meters in length. According to user needs, using multi-stage tandem installation, ultra-long-distance transport of materials. Able to maneuver work. I developed the production of mobile type shaftless screw conveyor, can motor work, use of a machine. Both the material below, but also the end of the material. Using a special lining, this machine can work at high temperatures. The compact, space-saving, good looks, easy to operate, economical and durable. 

 Tubular screw conveyor can be a screw feeder, this type of conveyor (feeder) and different trough screw conveyor, the feed inlet of the tubular screw conveyor in the feed side and a feed port, or into the hopper, trough screw conveyor is changed to the groove in the tube part of the spirochete, the use of two conveyor difference: smaller tubular screw conveyor throughput and conveying distance trough conveyors, feeding amount of differentiated tubular screw conveyor feeding amount is less than the trough screw conveyor. 

 Tubular screw conveyor, of course, also have a unique advantage: you can easily move, the tube that can be welded caster, convenient and mobile, flexible and convenient. And support each other with vibrating screen and other screening equipment used, to achieve energy savings of production costs, improve production efficiency effect. 

 In addition, according to the user requires the use of stainless steel to meet the food, pharmaceutical, chemical and other industries with special needs.
