New adjustable chip length drum chipper from Brunette
Brunette Machinery Company, Surrey, Canada, says its new drum chipper is an industry leader in producing quality pulp chips from short material that is difficult to control — including trim blocks, lily pads, log ends, overs and cores.
Brunette lists its key features as:
• Adjustable chip length to provide operators with the flexibility to choose desired chip length;
• Single piece tapered knives that process material across their full width, providing even wear and longer life;
• Quick knife changes can be done by one person. A hood opening and manual rotor lock prevent movement while changing knives, providing a safe working environment;
• The chipper accommodates large pieces through its wide throat;
• Electrical interlocks stop the chipper if the anvil releases;
• Pillow block bearings provide solid support to the rotor assembly;
• The rotor can be adjusted ensure an optimum knife-to-anvil clearance to suit the application;
• Heavy steel fabrication results in a high inertia rotor that can process high volumes and uses less energy;
• The rotor is mounted to a 5-in. ø HTSR shaft by two B-LOCs;
• HPU and cylinders are provided to open the large access hood for performing maintenance and knife changes;
• The chipping knives are tapered and sandblasted for added safety.
Features also include quick release, springloaded knife clamps, replaceable knife seats and counter knives. The fabricated screen is manufactured to limit the number of overs.
The hardened anvil is reversible for extended use and is designed to swing-away in the event of metal contamination. It is held in place by two shear pins mounted in B-LOCs.
Optional equipment includes an infeed chute that mates directly to the drum chipper to ensure a proper transition for material entering the drum from either a vibrating or belt conveyor.
