The principle of operation of the ball mill, the basic pulverizing device, was already known 150 years earlier; the prototype of the modern mill was invented in the 1870's. Methods of pulverization include crushing, impact, and grinding; compressive strain and shear are very important in these processes. In essence pulverization is a process ...
Abstract. This paper proposes an improved simulated annealing for ball mill pulverizing system optimization of thermal power plan. The proposed algorithm combines the simulated annealing and Tabu search and for the annealing operations, the current calculated solution is evaluated according to the neighborhood of the values in Tabu list.
My very first ball mill - such as it was - used a few pounds of stainless steel nuts and bolts for the medium charge. Ball bearings are very good for milling. Muzzle loading balls are, also. Fishing weights work (egg weights are about the best). Marbles work. Some people (scaring me as they do it) use glass marbles to mill black powder. LLoyd
