Overview

Hammer crushers use high-speed rotating hammers to break rock, concrete, and other materials by impact and shear. Common in aggregate production, recycling and construction, they offer high reduction ratios and can be installed as stationary, portable or track-mounted units to match site mobility needs. Buyers should focus on rotor speed, hammer material, feed size limits, wear parts availability and the unit’s service history to ensure reliable performance.

FAQ

What should I inspect when buying a used hammer crusher?

Check rotor straightness, hammer condition, wear liners, bearing play, gearbox and oil condition, feed chute wear and records of replacements. Look for signs of uneven wear or repaired cracks.

How do I arrange safe shipping for a hammer crusher?

Disassemble rotor and removable hammers for transport when possible, secure heavy parts, use certified heavy-haul carriers, obtain permits for oversized loads and plan lifting with certified rigging.

What regular maintenance keeps a hammer crusher reliable?

Inspect and replace hammers and liners based on wear, monitor rotor balance and bearings, change gearbox and engine oils per hours, clear feed and discharge, and keep vibration and temperature logs.
