Mar 11, 2016· Both processes can achieve small particle sizes and offer clear economic advantages and opportunity for scale-up. However, the technique for each is distinct. As compared to wet milling, high pressure homogenization reduces a sample’s particle size when it is forced through a narrow tube at incredibly high pressure.


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 ...
