Ball Mill method to extend the life of the cylinder carrying the crushing mill grinding work materials, in order to prolong the life of a ball mill, ball mill cylinder protection is the primary condition. 1, ball mill liner bolts must be on tight. When the mill operation should always check the liner bolts are loose and broken. Loose bolts should be tightened; the bolts to break or fall off the liner must immediately stop grinding process. 2, to be added between the ball and the ball mill cylinder liner layer lining the back, so close to the cylinder wall ball mill liner. Wet ball mill by grinding and slurry erosion even more, should be laid in between the ball mill cylinder liner and add a layer of plywood or wood 3 ~ 4mm thick rubber plate. 3, if the stop grinding a long time, should be discharged grinding to prevent Ball Mill due to local deformation by the weight of too long. 4, ball mill liner serious signs of wear or fracture when shall promptly replaced. Ball mill lining and grinding cylinder liner is used to protect the direct impact of free grinding and friction materials. Ball Mill for protection around these two points, slag mill, Ball Mill extend the life of the problem is solved. How to detect the amount of ball mill right fit? The so-called ball impact, the main ball should consider the size and proportion, as the number of ball in the production has been basically fixed, mill manufacturers, such as the central row of ore ball mill, ball its volume so as not to steel Get out of the ball from a ball mill is limited, Shanghai mill, and lattice-type ball mill volume should total about 50% by volume. During the test, as far as possible to keep the mill feed size, classifier overflow fineness and return the amount of sand and other operating conditions remain unchanged, then you can check the percentage of rationality ball from the following two aspects. 1, to the amount of ore grading machine and overflow fineness unchanged, ball mill price, and return the amount of sand is reduced, it shows the ball mill grinding action strengthened, then you can increase the volume of ore. 2, if the grading machine according to sieve analysis results back to the sand, found close to the overflow granularity of mineral particles increase, it means that an insufficient number of small ball; the other hand, if the increase in coarse, it means that an insufficient number of large balls.
