autogenous mill for iron ore laboratory

NRRI-TR-99-08 Cover

With the development of the autogenous wear surface, the high pressure roller press (HPR) is receiving interest from the mineral industry. Previous work by the Coleraine Laboratory had indicated energy saving using a single stage of HPR compared to rod milling and an energy saving using 2 stage HPR compared to single stage HPR.

Mineral processing | metallurgy | Britannica

A 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. Crushing/grinding


iron ore operation (McIvor & Greenwood, 1996). However, the beneficial gain from crushing critical size material is relatively proportional to the amount of critical size material in the circuit. For example, O’Bryan (1996) reported a negligible gain in throughput for a critical size material less than 5% of the feed of an autogenous mill.

Industrial Solutions Autogenous

air separator mill with drying 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
