Modeling cement clinker comminution with a perfect mix

In this paper, using a perfect mix model, mineral comminution modeling for vertical roller mill is done at nahavand cement plant. Perfect mix model provides a mathematical equation to the process of grinding in mills. For modeling, first sampling of flow of feed and product of working mill and then determined particle size distribution

Influences of operating parameters on dry ball mill

parameters such as mill speed, ball filling ratio, ball size distribution, powder filling ratio, grinding aid dosage and grinding time were studied. The results of grinding tests were evaluated based on the product particle size (d 50, d 80) and surface area (m2/kg). As a result of this study, optimum grinding test
