Standard Features of our Granulators Include:
Cutting Chamber
• Heavy duty one-piece weldment, fabricated from A-36 ground steel plate. It is rigid, smooth and easy to clean.
• Tangential feed design assures positive feeding of the material and maximizes throughput and helps prevent jamming.
• Also available, non-tangential feed, stainless steel, abrasion resistant, and water cooled cutting chambers.
• Cutting chamber is solidly welded on frame
• Swing-down heavy duty removable screen cradle (Hydraulically operated available on larger units).
Rotor
• Heavy-duty, SAE-1045 steel.
• Double scissor cutting action on rotor and bed blades assures positive cutting with minimum fines, and lower torque requirements.
• Micro adjustable bed blades are easily accessible from the front of the granulator.
• All ROTOGRAN blades are made from fully-hardened and precision ground D2 tool steel and cryogenically treated as an extension of the heat treat process.
• Rotor is offset in chamber for minimum fly-back and positive cutting of large or bulky items.
• Open rotor design allows more air flow through the cutting chamber for cooler operation and increased throughput.
• Alternative rotor designs are available on request.
• Our heavy duty, self-aligning flanged cartridge bearings easily absorb all grinding shock.
Flywheel
• Solid-steel construction minimizes motor and rotor abuse, reduces horsepower requirements, and electrical power costs.
Base
• Base frame is constructed from heavy duty structural sections, solidly welded to cutting chamber for vibration free operation.
• Heavy-duty steel casters on most smaller (2 rigid and 2 swivel), larger models on machinery mount.
• Acoustically-insulated panels, for maximum sound absorption.
Hopper
• Heavy-gauge steel. double wall construction.
• Conveyor or manual loading design is standard.
• Hopper is mounted on single point pivots to allow full access to cutting chamber (Hydraulically operated available on larger units).
• Double bulb neoprene extrusion on hopper's base helps assure complete sealing between hopper and cutting chamber (most machines).
Evacuation Bin
• Venturi style evacuation bin is constructed from heavy gauge steel with provisions for a blower/cyclone system connection.
• All granulated material is confined to the bin.
Electrical
• Nema rated across the line motor starter (Soft start and central control panels available).
• Strategically located electromechanical safety devices will automatically shut off power if an attempt is made to gain access to the cutting chamber or screen.
