Grinding Machines: Types and Selection Principles

The autogenous mill also has a selective grinding effect, and the phenomenon of over-crushing is less. In the grinding process, some steel balls can be added to eliminate "hard-to-grind particles", the so-called semi-self-grinding. The scope of application of the self-mill is limited, and there must be enough ore blocks that can be used as a medium in the ore being ground.

Stirred milling of nickel laterites for selective ...

Selective comminution of siliceous goethitic, saprolitic, and goethitic nickel laterites was investigated to upgrade nickel into the fine fraction using stirred milling. The breakage rates of minerals, grinding time, and the weight ratio of soft and hard minerals in the feed play an important role in selective grinding and nickel upgrade. When the grinding time and breakage rates were optimized, the weight ratio of the

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either
