Features at a Glance
The waste plastic crusher SL-60 and SL-80 are designed for high throughput rates, they are also called waste plastic cutting machines. they can crush almost all types of plastic. Plastic lumps, crates, films, bag scrap, pipes, automotive scrap, and blow-molded materials such as PE/PP bottles, PET bottles, buckets, drums and containers.
The first step of plastic recycling and sustainable processing is shredding with Shuily crushers. Crushing is the basis for all products made from recycled plastics.
Introduction of waste plastic crusher
The waste plastic cutting machine is used for crushing the PP PE material to small chips, it has the characteristics of high efficiency, low noise, and no slag material.
Shuliy industrial plastic crushers are extremely flexible and offer different rotor types, blade materials and screen sizes, therefore, they can crush a wide range of waste plastics. For example. thermoplastics such as PE, PP, PVC, PS, PU and PET, as well as injection molded product waste and blown films.
Even large-volume hollow bodies, long pipes and profiles, massive plastic lumps and bulks, as well as PET bottles, textile fibers, foils, insulating materials, crates and containers master industrial Shuliy crushers effortlessly thanks to 20 years of experience in the plastics industry.
Together with Shuliy crushing equipment recycling solutions, we develop single and multi-stage recycling processing, including crushing, pelletizing, and turn to plastic production directly in order to optimize the plastic lifecycle in the long term.
Wet washing for film materials
For the light weight of the plastic film, Shuliy recommends the recyclers use wet crushing method. Adding a water pipe for the plastic cutting machine. Using the impact of water flow, we can reduce the possibility of film stuck in the blades or rotor.
At the same time, the wet crushing process can enhance the water-cleaning effect of plastic scraps and reduce the friction heat due to the cooling effect of water, prolonging the service life of the blade, low maintenance cost, and long service life, therefore, so this kind of waste plastic crusher has received unanimous praise from customers.
Adjustable knives make perfect cutting gap
The interaction between the crushing blade and the fixed blade has an important impact on material throughput, as well as the crushing results. Typically, due to the different plastic materials, smaller clearances are required for shredding film materials and larger clearances are required for shredding hard materials.
To achieve an accurate cutting gap even when the blades are naturally worn, the Shuliy crusher has an adjustable bottom knife. The optimal cut shape maintains energy efficiency in shredding, minimizes wear costs, and significantly prolongs knife life.
Ready for fast material transport thanks to conveyor technology
Crushers with conveyor belt openings for efficient material transfer are ideal for recycling lines. For example, conveyor belts with a diameter of up to 500 mm are used in film pelletizing lines commonly. Additionally, discharge efficiency can be increased with fans, screw conveyors and U-conveyors.
Crushing rigids or films? You have choices with one crusher
Choosing the right screen is closely related to the shredding effect and output. Therefore, Shuliy Machinery, to give our customers maximum flexibility, i.e., convenience in processing different materials, our machines have individually replaceable screens.
Users can choose screens with different diameters mesh. Typically, a 40-50 mm screen is required to pulverize film materials, while hard materials such as car bumpers, meters, electric waste, crates or pipes need to be replaced with a 20-25 mm screen.
Plastic crusher machine application
The crusher for plastic waste is used to crush various plastics. The PP PE plastic shredding machine can crush a variety of soft and hard plastics, such as plastic tubes, plastic rods, plastic films, plastic toys, waste rubber products, and so on. Our plastic shredder uses alloy steel blades, which have high hardness and a long use time.
The crushed rigids can be called plastic regrinds, they can be reprocessed and pelletized in the next recycling process.

Working principle of waste plastic crusher
The waste plastic crusher drives the movable cutter head to rotate at high speed through the motor. In the process of high-speed rotation of the moving knife and the fixed knife, a relative movement trend is formed. The plastic crusher machine uses the gap formed between the movable knife and the fixed knife to create a cut for the plastic crushing and shearing, so as to smash the large pieces of scrap plastic. The crushed plastic is filtered and output by the screen to filter the plastic particle size. In addition, if your raw materials are soft plastics like plastic films and bags, it’s better to add a fan on the plastic crusher to avoid clogging.

The waste plastic crusher model is different from the blade width. The machine power and capacity are also different. Apart from SL-60 and SL-80, we also offer many other models of machines. For other needs, welcome to send us your requirements.
Precautions for the operation of crusher for plastic waste
1. The plastic crusher machine and power unit should be installed firmly.
2. After the waste plastic crusher is installed, check the fastening of each fastener.
3. Before starting the PP PE flakes shredding equipment, turn the rotor by hand to check whether the claws, hammers, and rotors are running normally and whether the power machine and the plastic crusher are well-lubricated.
4. After the plastic crushing machine is started, it should be kept idling for 2-3 minutes first, and make sure that there is no abnormal phenomenon before feeding work.
5. Pay attention to the operation of the plastic crusher machine at any time during the work. First, the feeding should be uniform to prevent from being blocked; secondly, do not overload the work for a long time. If any abnormal phenomenon is found, it should be stopped immediately for an inspection.
