Introduction:
Plastic crusher is used to crush waste plastics and factory plastic scraps. Plastic crushers are widely used in the recycling of waste plastics and the recycling and reuse of factory scraps. The motor power of the plastic crusher is between 3.5 and 150 kilowatts, and the speed of the knife roller is generally between 150 and 500 rpm. There are tangential feeding and top feeding in the structure; the knife roller has a solid knife roller and a hollow knife roller.

Principle of plastic crusher:
The plastic crusher drives the moving knife cutter head to rotate at a high speed through the motor. During the high-speed rotation of the moving knife, it forms a relative movement trend with the fixed knife. The gap formed between the moving knife and the fixed knife creates a plastic crushing and shearing incision. The block of plastic is crushed, and the crushed plastic is filtered through a screen to filter the size of the plastic particles.

Application:
plastic crusher can be used for the re-pulverization and recycling of all waste plastics such as boxes, thin pipe fittings, blow-molded parts, bottles, shells, and domestic plastic products, or as an auxiliary machine of the injection molding machine to re-pulverize the nozzle materials or defective parts of the injection molding machine.

Claw knife crusher
It is suitable for the crushing and reuse of various plastics, especially for various hard plastics (such as material ends, shoe lasts, etc.).
The crusher is easy to operate, simple and quick to change the knife; the optimized design of the knife holder, the claw-shaped knife can disperse the force, so that the shear force of each knife is increased, and it is suitable for crushing thick materials, hard materials, and other materials. Improve the cutting force of the tool and reduce the wear of the tool; it is equipped with an electronic control safety design, the hopper adopts a double-layer structure, and is filled with soundproof materials, which makes the equipment have good safety and environmental protection, and save electricity and durability.
1. All-steel welded machine base, strong and durable.
2. Easy to disassemble design, convenient for cleaning and maintenance.
3. Imported Minggang knives are sharp, easy to replace and durable.
4. Crush all kinds of soft and hard plastics easily.
5. Equipped with motor over-planting and electric interlocking protection system to ensure safe use.
6. Screens with different cutters and different hole diameters can be selected.

Blade Crusher
The structure of the sheet knife is between the claw knife and the flat knife. It is suitable for crushing plastic products and nozzle materials such as ordinary sheets, pipes, profiles, plates and packaging materials. The general-purpose plastic grinder adopts sealed bearings to keep the bearing rotation well for a long time; the design of the knife shape is reasonable, and the product is evenly granulated; the knife holder is heat-treated, and the appearance design is beautiful and generous.

Maintenance
1. The plastic crusher should be placed in a ventilated position to ensure the working heat of the motor is dissipated and extend its life.
2. Lubricating oil should be added to the bearings regularly to ensure the lubricity between the bearings.
3. Regularly check the cutter screws. After using the new plastic crusher for 1 hour, use tools to tighten the screws of the movable knife and the fixed knife to strengthen the fixation between the blade and the knife holder.
4. In order to ensure the sharpness of the cutting of the cutter, the cutter should be checked frequently to ensure its sharpness and reduce unnecessary damage to other parts caused by the blunt blade.
5. When changing the knife, the gap between the movable knife and the fixed knife: 0.8MM for crushers above 20HP is better, and 0.5MM for crushers below 20HP is better. The thinner the recycled material, the larger the gap can be appropriately adjusted.
6. Before starting for the second time, remove the remaining scraps in the machine room to reduce starting resistance. The inertia cover and pulley cover should be opened regularly, and the ash outlet under the flange should be cleared. The powder discharged from the plastic crusher chamber enters the shaft bearing.
7. The machine should be well grounded.
8. Regularly check whether the belt of the plastic crusher is loose, and adjust it in time.
