plastic shredder

The following is a detailed introduction to the plastic shredder:

Structural composition

- Blade group: usually composed of a moving blade and a fixed blade. The blade material is generally made of carbide steel or special alloy, with high hardness, high strength and good wear resistance, and can effectively shred various plastics.

- Knife shaft: It is the component for installing the blade. It is generally made of high-quality steel and has sufficient strength and rigidity to withstand the torque and impact force during the shredding process. The speed of the knife shaft is designed according to different materials and shredding requirements.

- Feeding system: including feed hopper, conveyor belt or screw feeder, etc., its function is to feed the plastic material into the shredder evenly and continuously. The shape and size of the feed hopper are usually designed according to the shape of the material and the feed amount.

- Power system: It consists of a motor and a reducer. The motor provides power, and the reducer converts the high-speed rotation of the motor into the low-speed and high-torque rotation required by the knife shaft to ensure that the blade can effectively shred the plastic material.

- Carrying box: It is welded with high-strength steel plates, used to accommodate and carry plastic materials during the shredding process, withstand the impact and pressure generated by the rotation of the blade, and ensure the stability and safety of the equipment.

- Electrical control system: Generally, a PLC control system is used, which can realize the functions of start, stop, reverse and overload automatic reverse control, and can also be equipped with automatic detection and overload protection functions to ensure the safe operation of the equipment.

Working principle

The plastic shredder mainly drives the reducer through the motor to drive the rotating knife shaft to rotate. The knives on the knife shaft cooperate with the fixed knives to shear, tear and squeeze the plastic materials entering the shredder, breaking them into smaller blocks or sheets. Some plastic shredders use dual-axis independent drive to make the materials produce corresponding pressure to achieve automatic feeding function. Its knife shaft structure and four-corner rotary knives will not cause the phenomenon of entanglement or jamming of the equipment during the production process of low speed and high torque, thereby improving production efficiency.

Performance characteristics

- Strong processing capacity: It can quickly and effectively crush various plastic materials into the required size. Its strong processing capacity can greatly improve the processing efficiency of plastic waste and save time and labor costs.

- Wide applicability: It can handle various types of plastics, such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), etc., whether it is hard plastic or soft plastic, whether it is large or small plastic, it can handle it.

- High safety: It is equipped with safety protection devices such as overload protection and emergency stop button to ensure the safety and reliability of the equipment during operation. At the same time, the shell of the equipment is made of steel, which is sturdy and durable, and can effectively prevent material splashing and personal injury.

- Environmental protection and energy saving: In the process of processing plastic waste, no secondary pollution will be generated. The crushed plastic materials can be directly recycled or further processed, which reduces resource waste and environmental pollution. In addition, the energy consumption during the operation of the equipment is low, saving energy costs.

- Easy to operate: The control system adopts intelligent design, which is easy and convenient to operate. Users only need to put the plastic material into the feed port, and the equipment can automatically complete the crushing process. At the same time, the equipment also has a fault self-diagnosis function, which can detect and eliminate faults in time, and improve the reliability and stability of the equipment.

Application field

- Plastic recycling industry: It is a key equipment in the process of processing waste plastics into plastic particles. It can tear various plastic products such as waste plastic bottles, plastic barrels, plastic films, plastic sheets, etc. into smaller pieces, providing crushed materials for subsequent granulation processing, and improving the recycling rate of plastics.

- Plastic product manufacturers: It is used to process plastic scraps and waste materials generated in the production process. After crushing, it can be directly reused in production, reducing production costs and improving resource utilization.

- Garbage disposal industry: In urban garbage disposal, plastic garbage can be shredded to facilitate subsequent classification, recycling and transportation, and reduce the pollution of plastic garbage to the environment.
