The combined mills are intended for crushing of a material with hardness up to 5 units as per Mohs scale, humidity up to 4 % and temperature of fusion not less 300°С, with getting of the product with the average sizes of particles less than 1 mm.
Operating principle for MPS-M and MPS-К1: the material is crushed from impact about beats of the first stage, rotor blades of the second stage and baffle plates of reservations. In the chamber of the first stage occurs large and in the second one occurs smaller crushing. The material is born from a mill by the stream of air created by rotor blades of the second stage through the outlet fitting.
The mill МCV-3 has three stages of crushing with a design of separate chambers connected consistently. Special set of elements of a rotor, change of sections of transitions between chambers; ways of the unloading as well as variants of high-speed modes give a wide range of variable characteristics of the mill. It allows receiving a wide range of granulometric size composition of finished product: from -300 microns up to -3 mm.

Characteristics are specified for base models.
As well as in other mills of fine grinding with an increase of grinding fineness the production falls and specific energy consumption grows. Depending on physical properties of a material (hardness, humidity, granulometric size composition of influent and effluent material, etc.) technical specifications of mills can vary.
Unloading branch pipe is recommended to be attached to the air line of an input in a cyclone with the bunker. Final clearing of air before emission to the atmosphere is carried out by means of the dust collector and the bag filter.
