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 ...
Lime ball mill advantages. 1. The lime ball mill adopts rolling bearings instead of sliding bearings, which greatly reduces friction, easy starting and significant energy saving; 2. It adopts a cone design at the discharge end. This not only increases the volume, but also forces the steel ball at the cone end to be classified.
