CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .

The ball mill was operating at 45 t/h during the audit period. Conventionally, a ball mill is preferred for fine grinding, whereas a rod mill is for coarser grinding (NapierMunn et al., 1996). The top particle size in the feed to the ball mill was 25 mm, which is very high for this type of mill.

Stirred media mill decreased bauxite d50 size from 780 to 5 µm in 3 min. But, the ball mill has reduced to 455 µm at the end of the same grinding period. In addition, the energy consumed by the ball mill for similar fineness (5 µm) was approximately 300 kWh/t energy, whereas the stirred media mill consumes approximately 174 kWh/t energy. As ...

Stirred mills were introduced to produce fine and ultrafine particles from coarse feeds at lower energy consumption [31]. It is a 3040% more energyefficient advanced grinding mill than the ball mill, especially for grinding below 100 μm [3236]. The breakage mechanism in stirred mills differs from conventional mills [37].
