Simple and Reliable

Rotochopper customers who have operated other grinders quickly come to appreciate the simplicity and reliability of our patented screen change system. The ability to quickly change screens reduces downtime and enhances versatility, allowing operators to easily swap screens to meet different end product specifications.

Damage Mitigation

Most screen installation systems use bolts or other fasteners to hold screens in place, but our unique system quickly secures screens in position with cam arms. Integrated shear protection limits damage from severe rotor impacts.
