New High-Throughput Granulators from Conair Feature Modular, Easy-Access Cutting Chambers

CKW granulator
   

The new CKW Series of robust, heavy-duty granulators from the Conair Group, Inc., can process up to 8800 lb/hr (4000 kg/hr). The cutting chamber can accommodate different replaceable back plates to create three different feed configurations, from open tangential to restricted. The bed knives, down-stroke cut and feed opening can each be fine-tuned to the scrap being processed, so the same basic granulator design can perform equally well on blowmolding, extrusion or injection-molding applications.

The CKW Series granulators feature 24-inch (600-mm) diameter rotors that are available in three different widths: 36 inches (900 mm) wide, 48 inches (1200 mm) and 60 inches (1500 mm) wide. A three-blade open rotor is standard equipment. Double-scissor cut herringbone knives adjust to ensure a consistent gap between the rotor knives and screen, producing a high-quality, uniform regrind with minimal dust, fines or heat build-up. Three-blade beam, five- and seven-blade rotors, and two additional bed knives, are available optionally.

The new CKW Series has a novel configuration that lowers the overall in-feed height of these large machines and provides easy access to all internal components for cleaning and maintenance. Instead of the conventional clamshell, in which the top of the unit tilts back and the screen and cradle drop down to provide access to the cutting chamber, the new CKW does it all with a large swing-away front-panel door. The screen cradle and granulate catch bin are actually mounted on the door (in front of the rotor, rather than underneath) so they swing out of the way as the door is opened. Then, with the power-assisted hopper tilted back, maintenance personnel can easily reach all areas of the cutting chamber. This unique design significantly reduces time needed for cleanout and material changeover, and simplifies access to the blades for maintenance.

Other key features include:

  • Heavy-duty transmission, with optional second flywheel and friction clutch for safety.
  • Power-assisted opening and closing of the in-feed hopper using gas springs or motor driven jack.
  • Safety interlock, which includes a speed sensor that prevents opening of the cutting chamber until the rotor has come to a complete stop.
  • Automatic rotor lock prevents rotor from drifting when the hopper is open increasing operator safety.
  • Ergonomic design allows critical wear-related components to be handled by a single operator.
