WhatsApp: +86 18203695377A special development is the autogenous or semiautogenous mill. Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.
WhatsApp: +86 18203695377AG mill (autogenous mill) is a mediumfree mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for selfgrinding. The ore larger than 100mm in the AG mill plays the role of grinding medium.

WhatsApp: +86 18203695377Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.
WhatsApp: +86 18203695377Mineral dressing. The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion ...
