Three kinds of faults of horizontal screw conveyor and treat

1. Blocking of horizontal screw conveyor
Main reasons and treatment methods:
1) Reasonable selection of screw conveyor technical parameters, such as slow screw conveyor speed can not be too large.
2) Strictly implement the operating procedures, start without load and park without load, and ensure the uniform feeding.
3) Increase the discharge port or lengthen the end of the chute to deal with the problem of poor discharge or too late discharge. At the same time, a small section of counter rotating blade can be installed at the end of the discharge chute to prevent material blocking at the end.
4) The materials entering the screw conveyor should be sorted out to avoid the blockage caused by large impurities or fibrous impurities.
5) Reduce the lateral dimension of the central suspension bearing as much as possible, so as to reduce the possibility of blocking when the material passes through the central bearing.
6) It is equipped with bin level device and blocking sensor to complete automatic control and alarm.
7) An anti blocking valve is set on the cover plate of the discharge end. When blocking occurs, the anti blocking door is opened because of material accumulation, and the power supply is blocked by the travel switch.
2. Horizontal screw conveyor drive motor burned out
main cause:
1) There are hard blocks or small iron blocks mixed in the materials transported by the screw conveyor, which block the cutter, increase the current and burn the motor.
2) The incoming material is too large, the motor is overloaded and burned.
Treatment methods of Jingjiang Weineng Machinery Co., Ltd
1) Avoid small iron block into and make the cutter and casing adhere to a certain gap.
2) Ensure that the feed is balanced and finished before shutdown.
3. Horizontal screw conveyor shell shaking
Main reasons: the center line of each screw section is not concentric when the screw conveyor is installed, and the shell shakes when the screw conveyor works.
Treatment: reset the device and align the center line.
