  • Vertical mill rollers and tires Magotteaux

    Due to the centrifugal force generated by the rotation of the main shaft the grinding rollers are pressed closely upon the grinding ring and grind the material fed into the mill (raw, cement or coal for instance) as they roll. The qualified material (i.e. the one which has reached the requested size) will leave the mill with the
