Electrical AC motor speed if a fixed value determined by the grid frequency and the number of poles in the stator winding. On principle, you use a Variable Frequency Drive only when you need to adjust the motor speed. This is done by adjusting the VFD output frequency. You can change the frequency so the speed from approx 10 to 200.

The company also obtained advantages such as speed setting according to momentaneous production and reduction of energy consumption from these other processes because when working with lower speed, the power consumed by the machine is also reduced for constant or quadratic torque loads which is the case of the conveyor belts, pumps and fans.
Roll crushers are often fed by apron feeders that direct feed material between a fixed and a moveable roll. The two crusher rolls, equipped with crushing segments, rotate inward and crush oversized material, while fine material passes the crusher without additional crushing. The adjustable gap between the crusher rolls defines the size of ...
Capacity Roll Crusher Calculations. Capacity roll crusher calculationsow to calculate the roll ty using a formula the theoretical capacity ng rolls is arrived at simply by calculating the volume of the cross section is the area of the discharge opening and whose length peripheral speed of the roll faces per unit of to calculate capacity of double roll.
Roll crushers have a theoretical MAXIMUM reduction ratio of 41. If a 2-inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 12 inch. Roll crushers can adjust the wedge device between rollers to control the feed and discharge size of the machine.
Double roll crushers help producers achieve the strict coal specifications they need to meet. Used as a primary or secondary unit, double roll crushers can be used in nearly any application with even the hardest, most abrasive material. This efficient crusher can lower power requirements for producing material and, with its unique features, can ...
Crusher segments last longer when the crushing is done efficiently, i.e. with the correct crushing ratio, roll speed and roll diameters are used. Direct saving in less frequent replacement costs and down time saving. Maximising Desirable Product Size Distribution
