Roller Crusher

The Haarslev Roller Crusher reduces cooked animal by-products to a consistent particle size before fat separation in dry rendering. Its dual-roller design is especially effective at breaking brittle bone and capturing large metal objects before they can damage downstream fat screw presses. With wear-resistant steel components, rotation monitoring for drive protection and a compact layout, the unit ensures reliable operation, longer equipment life and lower maintenance costs in dry rendering lines.
