Therefore, the company is now considering to buy a customized ball mill to increase the capacity of production. The ball mill have the capacity to grind 1400 kilogram in 3 hours while the same job was done by conche in 40 to 60 hours. The shortcoming of ball mill is that it could only done with grinding the aeration would be done in conche.
Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length to times the diameter. The feed is at one end of the cylinder and the discharge is at the other.
Ball Mill Parameter SelectionCalculation Power. 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting.
The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
