Furthermore, product and process quality improvements have resulted because of the consistent mill feed with each raw material. The key to the success of the bin designs was first knowing with a high degree of certainty how these bulk solids would behave as a function of the process conditions (moisture content, particle size, and storage at rest).

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
