For an (only nominally, not at all materially modified) update on its use for industrial mill sizing, see “ Selection of Rod Mills, Ball Mills, Pebble Mills, and Regrind Mills,” Rowland, C. A., Jr., 1982, Chapter 23, Design and Installation of.The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Each of these theories was useful in the design and scale up of' ball mill operations, however they told little of the expected size distributions, and most importantly gave no indication of liberation.
Work index of attrition ball mill Mining. work index of attrition ball mill The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100 passing 336 mm 6 mesh to product size in the range of 45150 m mesh thus determining the ball mill work index Wi B or BWi The work index calculations across a narrow size range are conducted using the.Filling Rates of the Mills. The mills should be filled with a suitable weight of rod or ball to benefit from most of the motor power. Filling ratios are generally 30-35 of the mill volume in rod mills and 40-45 in ball mills. Especially after rod charge, the charge swells up to 45 due to the coarse grain size (~25 mm) of the ore between the.
