A plastic crusher (plastic grinder) is a very important for in-house recycling. As per customer request, a plastic crusher with a rotor length between 300 and 1500mm produces from 400 kg/hr to 1500 kg/hr.
Plastic Crusher Application
Plastic lumps, sheets, films, pipes, tails, flashes, bottles, sprues, runners, rejects, etc.
Plastic Crusher Machine Intro
A plastic granulator ensures smooth size reduction of plastic and rubbery products, such as ABS, PC, PET, PVC in different forms. The plastic crusher is usually used as fine shredding due to its high rotational speed and sharp blades.
Featuring robust welded steel construction and small footprint, 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 crushing machine offers 2 types of rotors: one for soft plastics and the other for hard plastics.
The resulting regrind can be pneumatically conveyed and collected, forming a simple plastic recycling system with no dust and reduced labour cost.
Plastic Grinder Rotor
The rotor is the core of a 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. IBC drums and PC bottles).
The Difference between Granulator Rotor and Others
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.
Plastic Grinder Features
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.
The screen of the rubber granulator is easily interchangeable.
