Today, I will share a way to calculate the ball grinder.
The ball grinder is one of the important components of the mineral cost. It is more accurately determined to determine the ball consumption during the mill, and it is necessary to make a timely addition to obtain a good grinding effect on the ball mill. The so-called grinding ball consumption is generally referred to in the grinding ore, and the slight ball that is not recovered in the grinding product is lost during the grinding ore, and the shock of the cleaned, only as a scrap recovered, so It should be considered as a ball consumed. Ball consumption usually expressed with kg / t (primary mine).
[Example] Some factory 1500mm × 3000mm ball mill is initially installed 10T, and the parking inspection of the 2nd month after 3 months is 5000T, and all the balls in the machine are cleaned, sieved the reuse of the ball 9.5T; three A total of 6T balls were added, and the mill grinder was 1.3 (kg / t)
In order to maintain the ball load balance in the ball mill, the 1.3kg ball should be added to each grinding LT ore. As for more than big balls, how much is added, due to the wear of the ball is a complex process, usually simply supplement one or two larger balls simply, and regard the ball as a big ball. Due to the different ore properties, milling conditions, the material of the ball is different, it should be reasonably supplemented by the factory, and it does not lose, it is not blocked, ensuring that the ball mill is in a good working condition.
