O que é uma máquina trituradora de plástico?

I. Introduction

1. Definition and function

The plastic crusher machine, or merely put plastic broken, is a necessary machine in the plastic recycling field; it cuts plastic waste into smaller pieces or granules through physical cutting, tearing, and extrusion. This not only realizes the reduction in the volume of plastics but also forms advantageous conditions for subsequent recycling and reusing.

In the contemporary setting of more acute plastic pollution across the globe, the role of the plastic crusher machine is very important. It can mill all kinds of waste plastics in life, such as packaging materials, disposable plastic products, and plastic leftovers from all types of industrial production. The plastics are reprocessable, easy for the transference and storage of plastic particles, thus recycling plastic resources and hence forward the sustainable development of the plastic industry.

2. How Plastic crusher works

The plastic crusher machine works as a physical cut and crushing type. Components that make up this machine are high-speed rotating blades, hoppers, screens, housings, and drive systems. Waste plastic is fed into the hopper of the machine, from where it falls into the crushing chamber. Here the plastic material is cut by the high-speed rotating blades, and the impact and shear force of the blades on the plastic material causes it to further cut into smaller particles. The crushing is of the plastic material, and the resultant particles are made to pass through a screen; the aperture size of the screen will determine the size of the final particles. Smaller ones will smoothly pass through the screen while larger ones will be blocked going around for more circulation and crushing within the chamber until the final desired size is obtained.

II. Main components and their functions

1. Blades

The rotor and knives constitute the plastic crusher machine, which is made commonly from tough materials like high-speed steel and carbide- extremely tough and sharp, which rotate at high speed and cut into the plastic material, utilizing sharp edges and strong shearing forces to cut the plastic into its small pieces. The shape and setup of the blades can be changed based on the kind of plastic to be processed and the size requirements of the final fragments.

2. Hopper

The hopper holds the plastic waste to be processed and has different capacities based on the scale and application scenario of the crusher. It can hold hundreds of kilograms of plastic waste in a large industrial crusher at one time or just some kilograms in a small laboratory crusher. Some hoppers come with a guide so the plastic waste can slide properly and smoothly into the crushing chamber.

3. Screen

The screen is a key component for controlling the size of plastic particles after crushing. It is woven from metal wire and has a mesh size of a specific size. The crushed plastic particles need to be screened by the screen, and only particles with a particle size smaller than the mesh size can pass through, thereby ensuring the uniformity of the output.

4. Shell

Being woven from metal wire with a mesh at a specific size, the shell is another key component through which crushed plastic granules pass. The granules are made to pass through this shell and only those granules whose size is smaller than the mesh size pass through it. This provides for the uniformity of the output. The shell, which serves to protect the internal parts of the plastic crusher machine as well as to safeguard the entire operation process, too. It is often welded using high-strength steel plates, offering good stability and also good impact resistance against the various vibrations and impacts developed during the process of crushing.

5. Drive system

A motor by and large teams up with a reducer and a belt drive in the drive system for the plastic crusher machine. The motor changes electric energy into mechanic energy as the prime mover to supply the requisite power for the operation of the crusher. The reducer cuts down the rotation speed and enhances the twisting force so that the blade is able to rotate steadily within an appropriate speed range.

III. Industry application

1. Plastic recycling industry

The recycling process of the plastic recycling industry begins with the plastic crushers. The plastic bottles, packaging materials, plastic films, and other wastes are first crushed by plastic crushers installed at the recycling plant so as to reduce volume and make it easier for subsequent cleaning, separation, and reprocessing.

2. Plastic manufacturing companies

Healthcare facilities use plastic crushers to process scraps and unqualified products generated during the production process. After these waste materials are crushed, they can be added back to the production line and mixed with virgin plastics to produce new plastic products.

3. Healthcare field

In the healthcare field, plastic crusher can be used to deal with shredder waste, such as infusion bottles, disposable bottles, disposable plastic syringes, etc. After undergoing crushing as a pretreatment, then disinfection, and then other treatments, these agricultural waste plastics can be made into agricultural plastic granules. It does not come into humans direct.

4. Agricultural field

plastic crusher machines are also used in agriculture. If plastic products like agricultural films and irrigation pipes are just thrown away after use, it will lead to environmental pollution and wastage of resources. On the contrary, after undergoing crushing by a plastic crusher, these items can further be processed into plastic particles used by agricultural plastic products or soil conditioners, achieving the fact that waste agricultural plastics are resource-utilized.

IV. Conclusion

In short, as an efficient plastic waste processing equipment, the plastic crusher, with its abundant types and wide range of applications, provides a great boost to plastic resource recycling and actively responds to the global plastic pollution problem. Regardless of the size of a recycling plant or a large industrial plant, a high-quality plastic crusher can make a huge difference: improving working conditions, reducing production costs and minimizing the impact on the environment. It will be an economic and ecological advancement, an all-encompassing one.
