2) For the first time, add 80% of the ball mills maximum ball load. Why 80%, and not 100%. AS after the ball mill is installed, the large and small gears of the ball mill need to be meshed, and the processing capacity must be gradually increased. After the ball mill runs normally for two or three days, check the meshing of the large and small ...
Apr 11, 2017 In this case, it may be differ from the grinding balls bulk weight loaded to the mill. The formula for calculating the grinding balls mass in ball mill is given below (we will consider the measurements process and calculations in more detail in our next articles). The formula for calculating the grinding balls mass in ball mill
Oct 20, 2016 Grinding Balls. Steel balls ranging from to 5 in. in diameter are used. Rods range from 1 to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
Introduction A ball mill with simple structure and auto-flowing pulp discharge.
