Experts Show You Useful Methods to Control the Grinding Fineness of Ball Mill

Grinding is one of the most important steps that need high cost in the ore beneficiation plant. The grinding fineness of the ball mill has great influence on the gradation level of the minerals and the recovery rate of the materials. Therefore, how to effectively control the grinding fineness has been the concern for most mining machinery enterprises and customers. Here our experts will teach you some tips on how to make the best use of the ball mills for the perfect grinding effect.

First, the abrasion degree of the ball mill’s blades is a core problem we need to care about. When the blades are worn, few materials will be fed back which will cause the grinding fineness to become larger. And strong abrasion will influence the smooth work of the ball mill by reducing the service life.

Second, we should pay attention to the rotary speed of the ball mill. To rotate too quickly or too slowly will cause serious problems to the equipment. Therefore, before and during the operation of the ball mill and classifier, we should adjust the rotary speed to the proper one in order to guarantee the excellent performance of the mining machines.

Finally, the size and height of the classifier’s opening mouth used in the ore beneficiation process plays an important role in the mining industry. The bigger the opening mouth is, the larger the material feeding amount gets and the finer the grinding materials will become; vice versa. Therefore, we should adjust the size and height at a proper level in the installation process.

Our experts suggest that users should learn more about the factors that will influence the operation of the mining machines. To control the grinding fineness reasonably and effectively will surely increase the working efficiency and help us make more profits.
