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.
