The results are shown in table 26. When the conventional mill was loaded to 45 percent ball volume the weight of the balls was 1,271 pounds. When the loading of the mill containing the drum is expressed as 30 percent ball volume, for example, it was a proportional part of the abovementioned loading, namely 847 pounds.

A similar but smaller 30 cm x 30 cm (12inch x 12 inch) laboratory ball mill with 40, 30, 25, and 20 mm balls (1 1/2, 1 1/4, 1 and 3/4 inch) is used for their ball mill work index calculations. Stainless steel is suggested because the abrasion and corrosion will be negligible, it is easy to clean out and there will be no rust to influence the ...

First, ball mills are understood by the total volume in the cylinder when it is empty; This volume is based on the ball mill's diameter and the cylinder's length from the inside (refer to the Chart below for sizing). As a rule of thumb, 25% of the total volume of the ball mill is considered the "working" part of the ball mill.
