B02C17/00 — Disintegrating by tumbling mills, ... An autogenous grinding mill may receive a coarse run of mine rock feed and discharge it as a finished ground sand or slime product. In order to efliciently break down the rock the mill must provide both impact and attrition forces. In mills with substantially smooth linings and operating at

(Mining mill) Autogenous mill

Autogenous tumbling mill, also known as media free ore mill. According to the working conditions, it can be divided into dry self grinder and wet self grinder. The workingprinciple of the self grinder is different from that of the ball mill. The diameter of the self grinder cylinder is larger, and the grinding medium such as steel ball is not used

Experimental Analysis of Semi-autogenous Grinding Mill
