      Product Details

      Introduction and working principle >>>

      The shaftless screw conveyor is used for transporting all different types of wastes and filter residues generated in the industrial production process with its structural form as shaftless screw; The feed material enters from the feed inlet and is then conveyed to the tail end for discharge; except for the material buckets at the inlet and outlet, the entire conveying process is completed in totally enclosed tank; shaft-installed speed reducer is used as drive unit, at the end of the speed reducer is installed with bearing and dust-proof oil seals. No high-speed running parts are used during the entire running process of the equipment; wear-resistant nylon is lined at the lower part of the screw bringing less abrasion and low maintenance workload.

      Technical characteristics >>>

      The use of precision casting shaftless screw in the screw conveyor can ensure smooth delivery of the feed material with no problem of blockage;

      The drive unit installed at one end of the screw conveyor may be directly connected with the screw shaft with no more need of coupling;

      The screw conveyor trough is in U shape for its cross section; except that the feed inlet and outlet are open, all other parts are totally enclosed;

      The shell body, cover plate and feed inlet hopper of the conveyor are all reinforced with high strength to ensure the service life of the main body of the equipment;

      No use of bearings in the conveying trough to ensure smooth delivery of the feed material.
