OPEN MILL MIXING ON TWO-ROLL MIL RUBBER
Jul 20, 2013 · The mixing is often done on a two-roll mill (open mill). A mill consists of two horizontally placed hollow metal cylinders (rolls) rotating towards each other. The distance/gap between the mill rolls (nip) can be varied, typically between 2 to 20 mm. Rolls Friction Ratio The speeds of the two rolls are often different, the
Cement grinding Vertical roller mills versus ball mills
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the
