Engineering plastics are prevenlent in many aspects as they superior in thermal and mechancial property. Often, engineering plastics are produced in rod, plate and casing. The special shape and property pose a difficulty in recycling. The granulation of such reinforced plastics requires a heavy-duty shredder and a granulator to size reduce.
Engineering plastic shredder and engineering plastic granulator can work together like below to achieve the best effect.
The Wiscon recycling machines can be used in any application that needs predictable shredder and granulator quality. Typical applications include, but are not limited to, the following engineering plastics:
To downsize engineering plastic scraps, a powerful single-shaft plastic shredder is the your first choice for getting uniform particles. A low-speed rotor welded with D2 blades cut down plastic scraps as shown in the video. The horizontal pusher maintains a short distance between rotor and the lumps.
Secondly, it is a granulator‘s job to downsize the particles to 10-12mm. The drive power is enhanced to ensure a sufficient shearing force to break down plastic lumps. The largest of plastic granulator capacity is up to 2T/hr. This is well suited for large pelletizing companies and other recycling plant.
Another major feature is the heavy steel construction. The former uses thicker steel plate to fabricate. The engineering plastic granulator rotor is made from a hardened steel forged without any welding, as proof of extreme solidity, strength and resistance. The V rotor consists of multiple rotary blades and 2 counter blades.
The plastic lumps are transported from the end of the magentic separator to the input hopper of a granulator. This machine cuts the plastic waste into small pieces (flakes) which size will be determined by the screen. Usually the screen opening is 12mm.
During granulation process of dirty materials, water is optionally introduced inside the cutting chamber, so a big part of the material dirt is removed. There is a filter and a water recirculating system installed to optimize the water consumption of the system.
