Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.

Since the speed of an induction motor depends on the supply frequency, the VFD can be used to vary its speed. A VFD is a power converter that uses electronic circuits to convert a fixed frequency and fixed voltage into a variable frequency and variable voltage. It even enables a motor to run above its rated speed by increasing the frequency.
