How to Calculate a Ball Charge Load Level Reserve Calculations Accessory Rock-making Minerals … On the subject of ball size and ball charge in a grinding mill, … METHOD FOR ESTIMATING THE BALL CHARGE OF A GRINDING MILL …

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is

From these observations, a correlation between all kinds of circuits was established, regardless of the circuit's complexity level. Yingling (1990) used a Markov chain to model the mineral flow in mining operations. From this work, the conception of an iterative method for the calculation of the circulating load was achieved.
