Crushing and screening plants face some of the harshest operating conditions, such as quarries, aggregate production and mineral processing. The motor used in these plants must withstand heavy dust, continuous vibration and starting under heavy load. DRG Motor designs durable IE3 efficiency-class motors for these conditions.

The Challenges of the Crushing and Screening Environment

Crusher, jaw crusher, vibrating screen and belt conveyor drives run under constant impact and dust. The motor must therefore produce high starting torque and be protected in an abrasive environment. A wrongly chosen motor wears out quickly in these conditions.

Cast Iron Frame and IP55 Protection

In these applications a cast iron frame offers a clear advantage over aluminium against mechanical impact and vibration. IP55 protection guards the motor against dust and water ingress, while Class F insulation provides high-temperature endurance. This combination gives long service intervals in the quarry environment.

Torque, Speed and IE3 Efficiency

Crusher drives are mostly built with high-torque 4-pole (1500 rpm) or 6-pole (1000 rpm) motors. The IE3 (Premium) class lowers the energy use of the continuously running high-kW motors in these plants and reduces operating expense.

DRG Motor for Quarries and Plants

DRG Motor offers cast iron frame, high-torque IE3 motors from 0.55 to 355 kW for crushing and screening plants. By setting the right power, speed and frame type together according to your crusher and screen capacity, we build a solution that endures harsh conditions.
