Standard Horizontal Ball Mills are sometimes used for lime slaking. Considering that Ball Mills are designed for grinding, and the slaking process is simply a chemical process, it is obvious that the use of a Ball Mill for slaking is not the best choice of equipment in most cases. However, there are a few cases where the use of a Ball Mill ...

Preparations of pretreated silica, silica masterbatches and vulcanisates. Pretreated silica was prepared by ball milling the mixture of 60 g precipitated silica, 72 g TESPT and 480 g acetone contained inside a concealed ball milling container of volume 1242 cm 3 for 48 h. High amount of TESPT against the silica was added because it is anticipated the cascaded shearing effect of the ball ...

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.
