This example shows that grinding circuit simulation can be used to analyze the production circuit, to optimize the operating parameters and to reduce energy consumption. 4 Modeling a vertical roller mill A mathematical model for the grinding process in vertical roller mills has been made.

Cyclone Mill UDY Cyclone Sample Mills use a patented* method of grinding. High speed rotation of the impeller and air currents throw particles into, and rolls them around the grinding ring. Particles remain in the grinding chamber until impact-shattering and abrasion make them small enough to flow out the exit with the air current.

Cutting mills are used for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. The Cutting Mill SM 400 is suitable for primary cutting of large sample pieces measuring up to 170 x 220 mm but can also achieve the required final fineness in one step, depending on the application.
