Vertical Roller Mill As Pregrinding To Ball Mill

To decrease the specific power consumption in finishing process or to increase the output of finish mill vertical roller mill as pre-grinding to ball mill can also be introduced. Grinding capacity of finish mill increases about 30 - 60.To decrease the specific power consumption in finishing process or to increase the output of finish mill vertical roller mill as pre-grinding to ball mill can also be introduced. Grinding capacity of finish mill increases about 30 - 60.Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWht clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills VRMs with an integral separator as opposed to the use of VRMs as pre-grinding to ball mills is regarded as a breakthrough.Vertical roller mill VRM Ring roller mill or Horo mill Even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants.
