1 A background to drives of vertical roller mills 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
The speed at which the application will then operate depends on the designated speed (RPM) of the motor. Therefore, the main criteria for motor selection is torque. The following selector charts are based on the torques each of the motors will produce for various applications under different parameters.
Motor torque, load torque and selection of motors 2/43 2.1 Motor speed–torque curve Refer to Figure 2.1 where T st = starting torque or breakaway torque. T m = minimum, pull-in or pull-up torque. T po = pull-out, breakdown or maximum torque, obtainable over the entire speed range.
Four-roller mills Four-roller mills have two sets of rollers. When using a four-roller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits.
Vertical roller mill is a kind of grinding machine for cement raw material, cement clinker, slag and coal slag. It has the features of simple structure, low cost of manufacture and use.Vertical roller mill has many different forms, but it works basically the same.
