Used ROCA Impact Crushers

Overview

Impact crushers use high-speed impact rather than pressure to break rock, concrete, and other materials. They produce cubical product with good particle shape and are common in recycling, aggregate production, and secondary/tertiary crushing. Models range from stationary to portable and include rotor, blow bars, and impact plates. Buyers should match feed size, capacity, and wear-part availability to their material and operating hours.

FAQ

What should I inspect when buying a used impact crusher?

Check rotor condition, blow bars and impact plates for wear, frame for cracks, bearings, drive and hydraulic systems, feed opening size, and maintenance records.

How do I choose the right capacity and size?

Match the crusher to your feed size, required throughput (tph), reduction ratio and final product spec. Review manufacturer performance curves and consider material hardness.

What are shipping considerations for an impact crusher?

Confirm weight and dimensions, plan for disassembly if oversized, secure lifting points, obtain transport permits, drain fluids if required, and use experienced heavy-equipment carriers.

What routine maintenance is needed?

Regularly monitor blow bars, liners and rotor balance, lubricate bearings, inspect drive and hydraulics, clear feed areas and replace wear parts before failure.

How do I ensure spare parts availability?

Check OEM and aftermarket stock for blow bars, liners, bearings and rotor components. Verify lead times and interchangeability before purchase.
