A plastic granulator is a very important part of recycling. As per customer request, a heavy-duty granulator for plastic produces between 1200-2000mm rotor length with a capacity between 1000 kg/hr to 3500 kg/hr.
Plastic lumps, sheets, films, pipes, bottles, sprues, runners, rejects, etc.
Ensures smooth size reduction of plastic and rubbery products, such as PP, PE, PET, PVC in all sizes. The plastic granulator is usually used as secondary shredding due to its high rotational speed and sharp blades.
Featuring robust welded steel construction and stable operation, but during crushing, metal and similar hard foreign objects are not allowed to be disposed of into crushing chamber. 4 rotors are tailored for versatile applications and producing uniform regrind, whose size is determined by screen opening.
The plastic bottle crusher offers 2 major types of rotors: one for soft plastics and the other for hard plastics.
The resulting regrind can be pneumatically conveyed and collected, forming an in-house simple plastic recycling system with no dust and reduced labour cost.
The rotor is the core part of the granulator. Here at Wiscon, tailored to your applications, there are 4 types of rotors available:
The left is standard, covering downsizing tasks on light plastics (thickness < 5mm) and shredded plastics(40mm by 40mm).
The right is C-rotor, covering downsizing tasks on hard, thick plastic lumps and purges(thickness > 15mm).
The other 2 are for plastic film and hollow objects (e.g. drum and plastic bottles).
Wiscon granulator equips counter blades at 2 positions, front and rear. In bigger models, we have extra blades at the rear.
Multiple counter blades significantly increase crushing ability, because the materials are locked and shear multiple times.
All the rotors are self-made as we do not tolerate OEM. They are interchangeable for easy replacement and upgrade. After welding and machining, the shaft and rotor are heat-treated to strengthen the overall hard and wear-resistant surface.
Rotor blades and counter blades adopt D2 steel(60 HRC).
The main electrical components are trusted brands such as Siemens and Schneider.
Hopper & screen cradle are hydraulically actuated for easy blade & screen replacement.
Rotary and counter blades can be re-sharpened, greatly reducing operating costs.
Blades are pre-adjusted outside of the machine.
The screen of the rubber granulator is easily interchangeable.
Please refer to primary size reduction here: One Shaft Shredder
Side-feed Hopper – Prevents materials flying out from the crushing chamber by adding a side chute. Greatly ease long pipe feeding.
Swing Arm – A hydraulic device to force-feed bulky waste against the rotor.
Flywheel - An additional inertia wheel to increase crushing ability.
Water-cool - Embed a water pipe to cool down the crushing chamber.
Noise isolation – An extra casing helps reduce machine noise.
Belt Conveyor – Continuous material infeed and operates dependable on shredder/crusher workload.
Metal Detector – Stops for any foreign objects preventing them from reaching succeeding machines.
Wet Granulators - Contaminated plastics are granulated with a large amount of water, resulting in washing and shredding combined into one operation.
