But for vertical roller mills, the growth rate of that of material will gradually decrease. From this point of view, roller press is superior to vertical mill. In roller press, the contact area between the two rollers and the material is small the material is ground by only passing through the roller
Roller tables used in modern steel mills tend to use individually driven rollers rather than a single group drive such as a chain or belt. Roller tables require special motors with a high dynamic constant, plus a robust overall design to withstand the extreme heat and dirt of a steel mill. Such motors are used throughout the rolling mill on general conveying duties, but on the reversing mill ...

The roller mill drive consists of the motor and a planetary gear unit that was specially designed for roller mills. This gear unit is equipped with a hydrodynamic axial thrust bear-ing with partial or full hydro-static lubrication, which accepts the grinding forces and trans-mits them directly into the foun-dation of the unit.
Description. Designed for growing companies evolving from manual mill operations to computer numerical control CNC, Summit SmartCut EVS Series CNC Vertical Mills are a perfect fit. This CNC milling machine features the Fagor 8055i MC Control System perhaps the most versatile CNC due to its dual operating system.
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill sees instantaneously unless some damping system such as a surge hopper is used.
