LOESCHE Vertical Roller Mill - Influence of roller mass to mill loads -. Mass of parts in motion is responsible for: - dynamic load to foundation. - required foundation mass. - level of mill vibration. - load on mill structure. Loesche's Concept for larger grinding capacities: limitation of roller mass by using more rollers instead of.
Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque ,the gear unit also has capability to take up the.
