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

AMIT 135 Lesson 7 Ball Mills Circuits

Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges

Milling – fritsch de

The quality of every product or material analysis depends on the quality of the sample preparation It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice material properties feed size and volume of the sample grinding time and desired final particle size any abrasion of the grinding parts – all these factors are significant
