3200 Series Granulators

Typical applications for this 3200 Series of granulators are heavy extruder purgings, blow-mold flashing, sheet, pipe, large blow-molded parts (automotive, appliance, furniture, profiles), X-ray films, packaging films and large-capacity post-consumer products. The 3200 Series offers an extensive range of features and options in three model sizes: 32"x42", 32"x63" and 32"x84".

Unique features that abound within the new 3200 Series include the following:

• The conveyor infeed is 32"x63" for wide variety of product and high-capacity applications.
• A 12-Knife open rotor for improved throughput and part acceptance
• Optional rotors include a 30-Knife staggered "Hog" for the heaviest purging applications and a multi-knife Twin High Shear^TM rotor ideal for bulk film applications.
• The cutting circle measures 36" for extra-large parts and 20 percent greater screen wrap than most conventional designs for higher throughput capacity.
• A hydraulic tilt mechanism for the infeed hopper provides complete access to the cutting chamber and rotor for simplified maintenance.
• A drop-down screen cradle, also with hydraulic tilt, provides quick screen access.
• Discharge transition chutes roll out on tracks beneath the cradle for unmatched simplicity of access and cleaning. Twin-pipe discharge creates high-velocity material evacuation and efficient airflow, critical for high-capacity applications.
• Outboard-mounted integral bearing housings and heavy duty double row spherical roller bearings support maximum load-carrying capacity for the heaviest applications.
• Bearings are also close-fit, taper-mounted and adjustable for setting close radial clearances, which is critical for high-capacity film applications.
• A high-inertia rotor and rotor drive system create unmatched torque and driving force at the knife tip for unstoppable cutting action.
• An automated grease delivery system takes worry out of scheduled lubrications of bearings.
• The standard unit includes a 200 HP TEFC energy-efficient motor and options up to 400 HP.
• Safety interlock switches protect the operator and provide a safe environment for operation.

Variables such as material type, form and temperature, feed method, rotor configuration, knife sharpness and design, screen size, as well as evacuation system configuration all contribute to the overall capability of the equipment.
