When the coal weighing machine is running, it often fails because of coal blocking, mainly including coal blocking at the inlet, coal blocking in the shell, coal blocking at the outlet and so on. The shell and outlet coal blocking will cause the coal machine shell body full of coal powder, serious coal conveyor belt deviation, bearing damage, resulting in the machine can not operate normally, or even shut down, not only affect the normal coal supply of the boiler, but also increase the amount of labor of the operator. The following electronic belt scale manufacturer introduces how to deal with the coal blocking situation of coal weighing machine

1, the automatic control system for coal failure, when the amount of coal is too much, should quickly reduce the amount of coal, or stop the coal feeder, when the oil or pull the plasma combustion.

2. When there is too much debris in the coal mill, stone coal is not discharged in time and full of coal, strengthen stone coal emission.

3, the air volume is low, the adjustment is not timely, and the air volume should be appropriately increased for ventilation.

4. Design a reasonable outlet size to avoid coal flow into a dead Angle, so as to eliminate the phenomenon of coal blocking at the outlet of the shell.

5, can install coal blocking alarm device, when there is coal blocking, timely issued coal blocking alarm signal, in order to timely processing, in order to prevent coal blocking phenomenon further expanded, affect the normal use of the machine.
