the ball scats from a single-stage SAG mill. These scats are non-spherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates had increased dramatically at the coarser end of the size distribution.
intermediate size ready for final grinding in a ball mill, pebble mill, or VERTIMILLTM. Wet grinding is accomplished in a slurry of 50 to 80 percent solids. 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.
Aside from common ball mills there is a second type of ball mill called a planetary ball mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes.
