The treatment method of disintegrator malfunction

1, the mill does not open the control system does not trip, a trip on the open.

First of all, trip is caused by short circuit. The crusher does not open or trip, but the trip on opening indicates that the short circuit is caused by vibration after the crusher is started. Therefore, this kind of fault is most likely because of door protection or positive and negative travel switch wire broken skin or loose wiring, due to the vibration of the boot caused by short circuit control system trip.

2. During the start-up process, the grinder will sometimes stop suddenly, and then start again.

This situation should be analyzed from the working principle of the grinder. The ability of the crusher to start indicates that the controls are normal. However, in the process of starting, there will be a sudden stop, indicating that this phenomenon is caused by the vibration of the grinder after starting. For details about the cause and solution, see Article 1.

3, the current of the crusher is up and down, and the feeding is extremely unstable.

The current reflects the load of the equipment. The fluctuation of the current indicates that there is a problem with feeding, but the feeding frequency is certain, indicating that the feeding quantity is constant. Then why the current is suddenly large and small, and then think about it from the depth, because the grinder is a special equipment, it can carry out positive and negative control. So this kind of problem is caused by the discordant direction of pulverizer feed and the direction of pulverizer operation.

4. There are a lot of materials in the feeding mouth of the crusher or in the crushing room.

(1) The material spraying at the feed port of the crusher may be unreasonable adjustment of the hammer gap. Mainly because the hammer gap is too large to lead to the pulverizer spray;

(2) Another reason is that the direction of the mill feed is inconsistent with the direction of the mill operation. In the opposite direction, the hammer of the crusher will collide with the material, so that some materials will be sprayed out, and a long time will accumulate a lot of materials in the crushing chamber.

5. The crusher starts the star contactor and the positive and negative contactors do not pull together.

The main reason is that the positive and negative travel switches on site are inconsistent with the positive and negative selection switches on the control cabinet, or the positive and negative travel switches on site are not pressed and damaged.

6. Low output of crusher

(1) Check whether the grinder reaches the rated current;

(2) Check whether the assembly of the equipment is reasonable;

(3) Check whether the direction of crushing feed is consistent with the direction of the guide plate;

(4) Whether the air volume of the fan configured in the crushing system meets the requirements.
