The drive of a vertical roller mill – essentially the mill gearbox – has to fulfill two tasks: The first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor. Secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table, through the gearbox, into the mill foundation. Today ...

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 press once due to the large grinding ratio. In a vertical mill, there generally are two or ...
Manufacturers offer a wide selection of motors for industrial applications. Stepper, servo, ac, and dc motors can meet most industrial automation requirements, but the ideal motor depends on the application.

07/11/2015 For safety reasons, screws are preferred over belts or linear motors in vertical applications, as they help prevent a load from catastrophically crashing if there’s a loss of power to the motor. However, they can, and often will, back drive, depending on the screw’s friction, lead angle, and efficiency. (In general, lead screws have a lower tendency to back drive, due to their lower ...
