Plastic crusher: the core device of modern recycling industry
introduction
Plastic crusher, as a crucial equipment in the recycling industry, has been widely used in the recycling and reuse of plastic products. With the increasingly serious problem of plastic pollution, the demand for plastic crushers is also increasing year by year. This article will provide a detailed introduction to the principle, types, functions, and role of plastic crushers in environmental protection.
Working principle of plastic crusher
Plastic crusher, as the name suggests, is a mechanical equipment used for crushing plastic products. Its main working principle is to crush large or discarded plastic products into small particles or powders through mechanical force, making them easier to process and reuse in the future. A general plastic crusher consists of an electric motor, a frame, blades, a screen, and a discharge port.
The electric motor provides power and drives the blades to rotate through the transmission device. When plastic products enter the crusher, the rotating blades cut and tear them, and reduce their volume through continuous cutting actions. Then, the crushed plastic particles pass through a sieve, and larger plastic particles are returned to continue crushing until they reach the desired size and are discharged from the machine.
Types of plastic crushers
According to different working principles and purposes, plastic crushers can be divided into various types, including the following:
1. Cutting type crusher
The cutting type crusher is the most traditional type, which uses high-speed rotating blades to cut plastic. Suitable for harder or thicker plastic products, such as plastic bottles, plastic blocks, etc.
2. Crushing type crusher
The crushing type crusher adds crushing function on the basis of shearing and is suitable for crushing soft plastic products, such as plastic films, plastic bags, etc.
3. Grinding type crusher
Grinding type crushers crush plastic products into very small particles or powders through grinding, suitable for occasions that require high-precision crushing, such as the production of powder coatings.
4. Hybrid crusher
The hybrid crusher combines multiple crushing forms and is suitable for processing complex or mixed waste plastics, capable of simultaneously processing both hard and soft plastics.
The function of plastic crusher
1. Reduce the volume of waste plastic
One of the main functions of a plastic crusher is to reduce the volume of waste plastic, reducing its volume to about 1/20 to 1/30 of its original size. This is not only convenient for storage and transportation, but also beneficial for subsequent processing.
2. Improve the quality of recycled plastics
Through the crushing process, impurities such as dust, debris, oil stains, etc. in waste plastics can be effectively removed, thereby improving the purity and quality of recycled plastics.
3. Increase the recyclability of plastics
The crushed plastic particles can be directly used to manufacture recycled plastic products, or further processed into recycled plastic raw materials, which improves the recycling rate of plastics and effectively reduces plastic waste.
4. Reduce costs
After crushing waste plastics, the production cost of recycled plastics can be significantly reduced because the crushing process has already completed some initial processing, and the energy consumption and process cost required for subsequent steps will be reduced.
The role of plastic crusher in environmental protection
1. Reduce plastic waste
Every year, a large amount of plastic waste is generated globally, causing environmental impact
