The choice was to use two MH2 mills (1350×1500). These mills are designed for dry grinding of the material, have an internal drum volume of 2.5 m3 and a total load of grinding bodies up to 6.5 tons. The calculation showed that the mill of the first stage would be loaded with an assortment of steel grinding balls with an average diameter of 63 mm.

Common types of mills used in the food industry are: a) Hammer mills. A hammer mill consists of a horizontal or vertical cylindrical chamber lined with a steel breaker plate and contains a high-speed rotor fitted with hammers along its length. The material is broken apart by impact forces as the hammers drive it against the breaker plate. b ...
