Wet autogenous mills of MMS type are designed for grinding of ferrous and non-ferrous metal ores, raw materials, cement industry, diamond and gold containing ores.

MMS type mills are generally used for primary grinding. Use of large mills allows excluding the crushing stage. After addition of steel balls into the drum (on coordination with manufacturing plant of the mill and in quantity equal to 8–20% of the drum volume) the capacity will increase twice or three times (as compared with mentioned below).

The mill output for different types of ores is determined over wide range and depends on lump size and physical properties of raw material and final product fineness.

Raw material output of ММS 70×23С type mill is up to 500 t/h.
