Why does the limestone ball mill clogged?

　　The main function of the limestone ball mill is to grind the pulverized limestone to achieve the target particle size. However, the ball mill often encounters a problem that occurs and decreases in the operation. In response to this problem, we summarize the reasons why they may cause the ball mills, I hope to help you solve the problem.

　　1, the ball mill steel ball ratio is unreasonable, so that the unqualified limestone powder is frequently blocked by the fine powder warehouse. 2, the steel ball is poor and the wear is serious. The ball mill uses the steel ball of abrasive pulverized coal, during the process of grinding the stone, the steel ball is severely worn due to the strength of limestone.3, the gas tank pulse dust collector is not working properly, and the system negative pressure cannot be maintained.

　　4, the limestone quality is poor, blocking the fine powder warehouse. The powder system requires dryness, clean and clean, and the diameter is less than the parameters in the specified. If the limestone feed contains a lot of impurities, a large amount of impurities collectively in the ball mill exit, thereby causing clogging of the ball mill. 5, limestone open pins, the water content is large under bad weather. The desulfurization system has no design special stone storage field, and the stone is stacked. When it encounters rain, snow, the stone is tidy, and the ball mill is blurred. A large amount of moist stone is wrapped in the outer surface of steel ball and steel tiles, which will affect the normal operation of the ball mill, sometimes it is full, causing the ball mill to decline, and even forced to stop.

　　6, high-energy variable frequency selection machine adjustment is not suitable, affecting the fineness of limestone powder and ball mill. 7, running adjustment and maintenance and maintenance is not in place. The operator's inspection is not in place and the sense of responsibility, and the changes in system parameters have not been discovered in time, and the system is not adjusted, resulting in shortcoming of the ball mill and the system failure, so that the ball mill will drop. The maintenance personnel are not in place for equipment, and there is more defects in the system. The powder system cannot operate under a strong force condition.

　　The cause of the ball mill may be the above case. When such problems are encountered, you can check the failure of the ball mill. Of course, companies in daily use should also avoid things that may cause malfunctions, don't use it because of the ball millImproper to cause failure to affect production.
