Ball mill operation over a period of time, every 7 10 d to fill the ball, make steel ball gradation become very confusion.The longer you work, the more the ball series, grading of steel ball for ball mill is difficult to calculate.
Mill speed - critical speed.No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation.Too low a speed and little energy is imparted on the product.
The basic parameters used in ball mill design power calculations, rod mill or any tumbling mill sizing are material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating solids or pulp density, feed size as f80 and maximum chunk size, product size as p80 and maximum and finally the type of circuit openclosed.
Quite often, there is a need for a quick and correct calculation of a grinding ball surface area and volume.Necessity of such calculations may arise when choosing a container for reloading grinding media into a ball millwhen selecting the optimum characteristics of grinding ballsto suit specific grinding requirements, etc.
Ball mill is vital equipment in industries viz.Mineral dressing, ore processing,.Increase efficiency of the mill one would have to tune the rotation velocity so.Based on this equation it is possible to calculate, for example, the specific energy.
