The method of preventing blocking of screw conveyor

Screw conveyor because conveying material space is small, very sensitive to material; When the spiral shaft is twisted, it is easy to produce material entanglement. There are also central hanging bearing easy to block materials. So the blockage is the most common fault of screw conveyor, blockage light will affect the output, increase power consumption, serious will burn out the motor, twist the screw shaft, affect the normal production.

There are many reasons for blockage, and the following methods can be adopted to prevent blockage

1. Reasonable choice of screw conveyor technical parameters, such as slow screw conveyor speed can not be too large.
2. Strictly perform the operation procedures, do no load starting, no load parking; Ensure continuous feed averaging.
3. Add large discharge port or lengthen the end of the groove to solve the problem of poor or too late discharging. At the same time, a short section of counter-rotating blade can also be installed at the end of the discharge slot to prevent material blocking at the end.
4. The material into the conveyor needs to clear, in order to prevent miscellaneous or fibrous impurities into the machine caused by blockage.
5. Reduce the lateral size of the center hanging bearing as far as possible to reduce the possibility of clogging when materials pass through the center bearing.
6. Install silo level device and plug inductor, realize active control and alarm.
7. A blocking valve is provided on the discharge end cover plate. When the blockage occurs, because the material accumulates, the blocking door is opened and the power supply is cut off.
