Saturated grinding, also known as boring, full grinding, this is an abnormal grinding state, which should not occur under the normal operation of the ball mill. Its performance is mainly due to sound suffocation, current drop, output reduction, quilting by raw materials. Clogged, the abrasive body and the liner adhere to a large amount of raw materials. The occurrence of full-grinding of the ball mill is very harmful to the production of the equipment. The specific performance is that the inlet pressure is increased, the discharge amount is reduced, and even when it is serious, the material is not discharged, which seriously affects the production efficiency of the equipment. What is the reason for the ball mill to be saturated? There are many reasons for the equipment to be full, mainly including the following points. 1. Excessive feeding causes the grinding ability of the grinding body to be unsuitable. 2. When the particle size of the material becomes larger and the wearability deteriorates, the feeding is not reduced in time. 3. The material moisture is too high, and the ventilation is poor, which causes the material to adhere to the surface of the steel ball and the lining plate, blocking the gap between the slab and the slab, and the discharge is difficult, resulting in full grinding. The "satisfaction" caused by this reason is more common. 4, the scrap iron, debris: blocking the slit diaphragm plate grate. 5, warehouse: the average ball diameter of a warehouse steel ball is too small, the filling rate is too low, or too much lower than the second warehouse; the partition plate is partially broken or perforated, causing the grinding body to close the warehouse. 6, the grinding ability can not be adapted: the powder selection efficiency of the classifier is reduced, the amount of returning material is too much, the grinding ability of the ball mill can not be adapted. How to solve this situation? The experts give the following three suggestions. 1. Reduce or stop feeding, strengthen ventilation, and let the mill run under less material or no material. 2, increase the heat, so that the moisture of the material evaporates as soon as possible, so that the material falls. 3, the phenomenon of full grinding is more serious, you can use the method of back grinding, pour out the ball and material, and then clean it up. The Red Star machine still recommends that everyone pay more attention to all aspects during the use of the equipment, strictly abide by the operating rules, regularly check and maintain, and try to avoid this situation.
