Heavy-Duty, Double Feed Roller
Harris scrap and auto shredder systems implement a sturdy reinforced steel plate yoke with our exclusive 3-tube design for enhanced rigidity to torsion. Our “Quick Release” design allows the removal of the complete roller without completely disassembling components. The continuous large diameter torque tube pivot distributes loading along a larger area. Tube sits on large steel split pillow blocks with bronze bushings.
Large mechanical locks allow safe work conditions during maintenance. The hydraulically actuated locks allow positioning from a remote safe location. Harris’ patented Teflon seals allow the best sealing capability in this heavy duty environment. The Teflon seals permit the re-honing of the cylinder tube to non-commercial sizes for extended service life.
Rotors and Drive Mechanism
Harris offers welded and non-welded disc and 4-arm spider designs. Each disc, spider arm and spacer is shrink fitted and keyed to the shaft while the complete assembly is secured by tie-rods. Harris uses high strength steel alloy plate on all rotors. The end discs have replaceable caps for better wear resistance. Replaceable heavy-duty helmet cast steel caps protect the spider arms.
Rotor Bearing Housing
Rotor bearing housings are machined from high strength forged alloy steel. The internal lubrication connections allow placing fittings only on the outboard side for easy maintenance. The closed loop oil recirculating unit provides filtered and cooled oil to the bearings
Harris Production Management system (HMPv.1) provides real time access to production rates, energy usage and critical operational feedback from the comfort of the operators chair fit with intuitive joystick controls.
The Harris HMPv.1 management system can be retrofitted to existing systems to provide your plant with vital operations data.
