Temperature Reduction for Ball Mill Optimization | Lechler US
A ball mill is a type of grinder commonly used for crushing or milling materials into an extremely fine form. A ball mill's cylindrical shell is filled with large cylindrical pellets made of some material (typically stainless steel, or rubber). When the shell is rotated around its axis, the internal cascading effect of these balls and the ...
