AUTOGENOUS MILLS AND SEMI-AUTOGENOUS MILLS

In the process of autogenous grinding, the material itself is used as a grinding body. In the course of semi-autogenous grinding, auxiliary grinding media (usually steel balls) are used. Metso's MSI/MPSI mills are ideal for grinding ore or primary crusher products. This line of mills includes models of various sizes and capacities:

  • Diameters from 1.8 m to 12.8 m
  • A capacity of up to 28 MW
  • Synchronous, asynchronous (induction) and wound-rotor motors
  • With rolling or plain bearings (hydrodynamic or hydrostatic)
AUTOGENOUS MILLS AND SEMI-AUTOGENOUS MILLS

Due to the fact that MPSI mills can process clay and wet material, they are often used to prepare material before grinding in ball mills.
