Stone crushing plant motors are heavy-duty electric motors designed to withstand the demanding operating conditions of crusher systems. DRG Motor's crusher motors provide uninterrupted performance in stone crushing and screening plants with high starting torque and resistance to impact and vibration.

Features Required in Crusher Motors

Stone crushing applications have sudden load changes and a continuous need for high torque. For this reason, the body is cast iron, protection is IP55 and the insulation class is F. Being designed to withstand 24/7 heavy-duty (S1) conditions, they increase plant efficiency and motor life.

Which Motors Sit in a Crushing Plant

A crushing plant rarely needs one motor. The jaw or impact crusher takes the largest step, the screen runs on a vibration motor, and the conveyors and water pumps sit lower in the range. All of them come from the same 0.55–355 kW line, in IE3, IE4 and IE5 efficiency classes and in B3, B5 or B35 mounting.

What the Cast Iron Body Has to Take

Windings are 100% pure copper, the body is cast iron, protection is IP55 and the insulation class is F, to IEC 60034 and European Union Ecodesign. Crusher duty adds dust and impact to that list, so the vibration result is the one that decides here. Insulation, vibration, efficiency and load values are recorded before shipment.

When a Crusher Motor Stops Mid-Season

A stopped crusher costs a working day, so the common crusher steps are kept in the İzmir stock and shipped to any province without waiting for production. If the failed unit is a special power or speed, a photograph of the nameplate is the quickest route: frame size, shaft diameter and mounting read off the plate save re-measuring the foundation.

What We Need to Quote a Crusher Motor

Crusher capacity in tonnes per hour, the material being crushed, the power in kW and the speed in rpm are enough to start. Our technical team returns a model with its stock status and delivery date.

Frequently Asked Questions

What power motor is needed for stone crushing?

The motor power is determined by the crusher's capacity and the hardness of the material. High kW values and high torque are usually required; for the right selection, simply share your plant information with our technical team.

Can one supplier cover the whole plant?

Crusher, screen, conveyor and pump drives all come out of the same 0.55–355 kW range, with the speed and mounting chosen per position. Ordering them together keeps the spare parts list and the delivery on one line instead of four.
