— Drive trains of vertical roller mills are usually equipped with heavy duty gearboxes with a horizontal input shaft and a vertical output shaft. Increasing mill sizes bring the existing gearbox concepts to their limits, however. This, and the demand for higher reliability and lower costs, has forced gearbox manufactures to develop new gearbox …

 — Our flagship mills are centrifugal ring-roll pulverizers – equipped with three pendulum roll assemblies suspended from a rotating carrier. Leveraging centrifugal force created by the rotation of the carrier, the roll assemblies swing outward causing the roller at the bottom of the roll assembly to rotate against the inside of the stationary ring.

 — Fig. 2 depicts the sites of two sampling ports on the mill shell. The classifier feed was collected from port A, which was located below the classifier inlet vanes. Port B was drilled for sampling the classifier reject. There was a pipe that cut through the mill body and reached the classifier cone. PF was directly collected from the PF pipes.

Common classifier mill variations Other common air classifier mill variations include mills with a horizontal classifier wheel, a combined classifier wheel and rotor drive, a vertical rotor, or an easy-to-clean design. Their operation is similar to that of the vertical air classifier mill, but they're configured differently. Horizontal wheel.

Concept of Classifier for Ball Mill LVT started to design new Classifier for ball mills in the beginning of 2001. The concept and construction are very unique applying new technology. The basic concepts are; 1. Material feed at Separator bottom 2. No bucket elevator system for new grinding plant 3. Fluidizing bed
