Vertical Ball Mills. When lime or water quality is poor and/or when lime consumption rates are high, STT designs slaking systems utilizing a vertical ball mill. The total grinding process of a vertical ball mill utilizes all residual reaction value, virtually eliminates grit disposal problems, and significantly improves lime usage efficiency.Web

Dry agitated bead mill. The mill design is based on the wet-operated LMZ bead mill series by NETZSCH Feinmahltechnik . The dry development - called SpeRho - was led by NETZSCH Trockenmahltechnik . As shown in Fig. 1, it is a horizontally operated mill with a grinding vessel and a shaft equipped with agitators.Web

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: …Web

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.Web
