Stone crushing plants are among the harshest duties for electric motors: sudden load changes, constant dust, vibration and long running hours all occur together. DRG Motor's İzmir-made electric motors are built to withstand these conditions on crusher and screening lines, with a cast iron frame and high starting torque.

How the Crusher Load Affects the Motor

In jaw and impact crushers, the moment rock enters the chamber a sharp torque load is placed on the motor. This shock-loaded regime means the motor needs high breakaway torque and a rotor design that can deliver it. A motor with low starting torque struggles in this application and overheats frequently.

Protection Against Dust and Vibration

On the crushing site, IP55 protection keeps fine mineral dust away from the windings. Class F insulation provides a high temperature margin, while the cast iron frame holds its dimensional stability under constant vibration. This combination markedly reduces unplanned stoppages and winding failures.

What the Efficiency Class Adds

Because crushing lines run for long hours each day, IE3 and IE4 efficiency-class motors perform the same work with lower losses and cut the energy bill. Screening units, conveyors and dust-collection fans can be served from the same efficient motor family, giving consistent maintenance and spare-part management across the whole plant.

Selecting the Right Motor for the Crushing Line

DRG Motor supplies B3 foot-mounted motors from 0.55 to 355 kW suited to the heavy starting torque of stone-crushing duties. To define the right motor for the speed and power needs of your crusher, screen and conveyor drives, contact DRG Motor.
