Hi collegues, a month back i asked for help to increase grind size but i did not have enough data. now i have the data. i am currently grinding to an average of 110 microns but i would like to increase to 150. mill throughput is now at 70 t/hr. the ball mill is in closed circuit with the cyclones. mill diameter inside liners is 4m, effective grinding length is, critical speed is % ...
WhatsApp: +86 18838072829This study investigated the effect of grinding media on the finegrinding performance in the wet tumbling mill. Comparative experiments between cylpebs and ceramic balls were conducted in a laboratory wet ball mill under various conditions, such as different total masses, total surface areas, and total numbers. The results indicated that ceramic balls produce a slightly smaller instantaneous ...
WhatsApp: +86 18838072829mill has insufficient processing capacity and easily throws stones For some ball mills, the feed amount of the mill is far from the design capacity in actual operation. When the feeding amount exceeds a certain limit, ball mill will throw out unground stones at the outlet, and the amount of stones thrown out is large.

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.

The equivalent granule size declined while its specific surface area increased gradually with grinding time [23]. The grinding kinetics of quartz and chlorite followed the firstorder breakage behavior in wet ball milling [24].
