Multi shafts screw conveyors are used in the flour milling industry, especially for conveying cereal grains,flour , and by-prosucts such as bran. Multi shaft screw conveyors are manufactured from carbon steel with food-grade surface finishing .They are made up from a U-shaped trough that is equipped with at least one outlet spout,an end plate at each trough end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end ,two end bearing assemblies complete with shaft sealing unit,a number of intermediate hanger bearings with self-lubricating bushes depending on the overall length of the screw conveyor, and bolted trough covers.

b. When WLS non-shaft screw conveyor is initial feeding, the feeding amount should be gradually increased until it reaches the rated conveying capacity, and the feeding material should be uniform, otherwise it will easily cause the accumulation of conveying material, overload of the drive device, and make the entire WLS shaftless Screw conveyor damaged.
e. Always check the working status of each part of the WLS shaftless screw conveyor during use and pay attention to whether the fasteners are loose. If the parts are found to be loose, the screws should be tightened immediately to make them resolidified.
f. The cover of the WLS shaftless screw conveyor should not be removed when the machine is running to avoid accidents.
