WLS-type shaftless screw conveyor by driving means, shaftless spiral, U-shaped groove, lined plate, cover, into the hopper, the discharge port and other components. WLS-type shaftless screw conveyor and its working principle is: the material from the hopper into the conveyor auger from rotating shaftless sent to the discharge port. WLS shaftless screw conveyor type Features: WLS-type shaftless screw conveyor screw conveyor compared with conventional shaft, the use of non-central axis design, the use of a certain flexibility of the overall steel auger material, which has the following outstanding advantages: WLS-type shaftless screw conveyor strong anti-winding. No central axis interference, for conveyor-like, easy to wound materials have special advantages. WLS-type shaftless screw conveyor good environmental performance. Fully enclosed screw conveyor and easy to clean surface, to ensure the delivery of health and the environment from pollution materials, do not leak. WLS-type shaftless screw conveyor torque, low energy consumption. Because shaftless spiral, material clogging, discharge opening is not blocked, which can lower speeds, smooth transmission, reducing energy consumption. Torque up to 4000N · m. WLS shaftless screw conveyor transporting large type. Transportation volume is 1.5 times the same diameter conventional shaft screw conveyor. WLS shaftless screw conveyor type long distance transport. Single conveyor lengths up to 60 m. According to user needs, the use of multi-level series-mounted, ultra-long-distance transportation of materials. WLS-type shaftless screw conveyor can flex. Our development and production of mobile type shaftless screw conveyor, can maneuver work, a multi-purpose machine. WLS shaftless screw conveyor type either beneath the material, but also ends the material. WLS shaftless screw conveyor using a special type of liner, the aircraft can operate at high temperatures. Compact WLS shaftless screw conveyor type structure, space-saving, good looks, easy to operate, economical and durable.
