Screw conveyors are used to continuously transport powdered and small-sized materials such as grain, feed, pulverized coal, cement, clinker, compound fertilizers, sand, grains, coal, and stones. Its structure is simple and novel, easy maintenance, advanced technology, small cross-sectional size, good sealing performance, safe and convenient operation, easy to install and discharge in the middle; the middle hanging bearing adopts rolling or sliding two structures, all set dustproof, sealed Device, easy operation and maintenance.
The most common failure of screw conveyors is blockage. There are many causes for blockage. To prevent blockage, the following actions can be taken:
Spiral conveyors can be used to increase the discharge port or lengthen the end of the chute to solve the problem of poor discharge or too late to discharge. At the same time, a small section of anti-rotation blades can be installed at the end of the discharge chute. To prevent blocking of the end, such as slow screw conveyor speed can not be too large. Strict implementation of the operating procedures, so that no-load start, empty parking; ensure continuous average feed; the necessary materials to enter the conveyor to clean up, to prevent large impurities or fibrous impurities into the machine caused by blockage. The bin leveler and the jamming sensor are installed to achieve automatic control and alarm; an anti-clogging valve is set on the discharge end cover. Minimize the transverse dimension of the middle hanging bearing to reduce the possibility of material blocking when passing through the middle bearing.
