how to solve the problem of full grinding ball mill?

I believe that many ball mill users have heard or experienced ball mill full grinding, but do you know why the ball mill will appear this situation?

full grinding is also called stuffy grinding and full grinding. This is an abnormal grinding state and should not occur under normal operation of ball mill. Its main manifestations are sound stuffy, current drop, output reduction, grate seam blockage by raw materials, and a large amount of raw materials adhered to grinding body and lining plate.

ball mill is very harmful to the production of equipment. The specific performance is that the import pressure increases, the discharge volume decreases, and even the material is not discharged in serious cases, which seriously affects the production efficiency of the equipment.

What is the reason for the formation of ball mill full grinding? There are many reasons for the emergence of full grinding equipment, including a few points.

1. Excessive feeding leads to the grinding capacity of the grinding body cannot be adapted.

2. When the particle size of the material becomes larger and the grindability becomes worse, the feeding is not reduced in time.

3. Excessive moisture content and poor ventilation of the materials cause the materials to adhere to the surface of the steel ball and the lining plate, blocking the gap between the bin plate and the grate plate, and causing full grinding due to difficult discharging. This reason caused by the "full grinding" more see.

4. Iron filings and sundries: block the grate seam of the partition board.

5. Warehouse: The average ball diameter of steel balls in the first warehouse is too small, the filling rate is too low, or too much lower than that in the second warehouse; The partition plate is partially broken or perforated, causing the grinding body to move into the warehouse.

6. The grinding capacity cannot be adapted: the powder selection efficiency of the separator is reduced, the amount of material returned is too much, and the grinding capacity of the ball mill cannot be adapted.

how to solve this situation? experts give the following three suggestions.

1, reduce or stop feeding, strengthen ventilation, so that the mill in less material or no material operation.

2, increase the heat, so that the moisture of the material as soon as possible evaporation, so that the material falls.

3. If the phenomenon of full grinding is serious, the treatment method of inverted grinding can be adopted to pour out balls and materials and clean them again.
