Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.

DESIGN AND ANALYSIS OF BALL MILL INLET CHUTE FOR

2019-4-21  In ball mill, ball has to be charged around 30-32% in first and second compartments. Balls are in the range of 50-90mm in coarse and 15-50mm in fine grinding. Grinding of material takes place by means of collision or attrition or tumbling action takes place between the balls and the charge.

2018-12-9  In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

Comminution circuits for gold ore processing -

2005-1-1  Traditionally, many engineers have approached SAG circuit design as a division of the total power between the SAG circuit and ball-mill circuit, often at an arbitrary power split. While this approach may result in a successful design, it ignores the critical decision of determining the correct power split between the SAG and ball-mill circuits.
