The ball mill in a concentrator is mainly composed of feeding part, discharging part, rotating part, and transmission part (speed reducer, small drive gear, motor, and electric control). The cylinder is generally cylindrical (except cone ball mill). The grinding medium is usually steel ball, steel rod, or gravel, with a diameter of 25–150 cm.

Grinding—Two Stage Rod and Ball Milling. Two- stage grinding provides the grinding economies outlined in DECO Bulletin B2-B13. In the wet grinding circuit, a rod mill takes the entire feed at ¾" and reduces it to approximately 14 to 20 mesh. This mill is normally operated in open circuit with the classifier and ball mill.

Maximising the mass fraction of m 2 in the product in a single ball mill. If the objective is to find the best feed PSD to optimise the mass fraction m 2 in the product, then the AR in Fig. 7 shows that for Feed 7, the mill would be operated up to a point corresponding to m 2 of about 66.7%, and m 1 of 9.8% with m 3 = 23.5%

Abstract. Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best make-up ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range (i.e ...
