U21-BKV type screw conveyors for food industry: U21-BKV-20-20

Screw conveyors are designed for horizontal or inclined (up to 20 degrees) movement of grain and products of its processing. They are used as a part of technological lines of elevators, mills, groats plants, feed mills, FDS, MOB, oil plants. Screw conveyors consist of the following parts: a screw formed by a spiral surface welded to a tubular shaft; chute or cylindrical casing with outlet spigots; intermediate (suspended) and end bearings, one of which is thrust; drive.

The principle of operation of screw conveyors is based on the continuous movement of grain rotating auger, installed in a fixed chute. There is a distinction between slow-moving and fast-moving screw conveyors. In slow-moving horizontal and declined conveyors the product is kept from turning by the force of gravity and friction on the chute.

Once in the working area of the auger, the product slides along the auger from the loading area to the unloading area in a spiral motion. The auger is driven by the...
