Sugarcane Shredder

A sugarcane shredder uses swinging hammers on a high-speed rotor to break cane into fibers and improve juice extraction in subsequent milling. Wear is concentrated on hammer tips, hammer bodies, grids and feed and discharge impact zones. Main shafts, hammer pins, bearings and seals are key maintenance parts.
