chamber for iron ore grinding. The single-compartment mill is ideal for the grinding of fine-grained feed material. One typical application is the combined grinding and drying of iron ore concentrate with a high feed moisture content (up to approx. 8 %). High-efficiency separators minimise the power consumption of dry grinding systems.

Grinding is conducted wet, and chemicals such as lime, soda ash, sodium cyanide, and sulphur dioxide may be added in the grinding circuit in preparation for ore separation. Ore must be ground fine enough to liberate the ore minerals from the gangue, or subsequent separation methods will not be as effective.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Semi autogenous grinding and autogenous grinding circuits are used for grinding the ore. Both rod mills and ball mills are used for this purpose. Capital investment and operation costs of grinding equipment are high. Hence economics play a large part in planning for the degree of crushing and grinding performed to prepare ore for beneficiation.

PRODUCT . Wet grinding equipment is to grind the raw material suspended in the carrier liquid with appropriate additives such as dispersants. When the water content is over 50%, the problem of dust flying can be solved. In food processing, due to the ability of making the ingredients easily soluble, grated materials are usually prepared for leaching, thus wet grinding is very suitable.

Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.
