Comprehensive Guide to Plastic Shredders


Plastic crusher is a kind of equipment used to crush and crush plastic products. It usually includes a mechanical structure composed of blades, rotors, screens, etc. It plays an important role in plastic recycling, reuse and waste disposal.

Definition of plastic crusher

Plastic crusher is a mechanical equipment used for crushing and grinding plastic products. It can handle various types of plastic products, such as waste plastic containers, plastic packaging, plastic pipes, etc.

Purpose and application fields

Plastic recycling: Plastic crusher is one of the indispensable equipment in the plastic recycling process. By crushing waste plastic products into small particles, subsequent reprocessing and recycling can be facilitated.
Plastic recycling: Crushed plastic particles can be used in the production of recycled plastic products, such as recycled plastic packaging, recycled plastic furniture, etc., which helps reduce the demand for original ecological plastics, reduce resource consumption and environmental pollution.
Waste treatment: Plastic crushers are also widely used in municipal waste treatment plants to process large amounts of waste plastic products, reducing the volume of waste and facilitating subsequent processing and disposal.

Working principle of plastic crusher

The working principle of the plastic crusher is relatively simple and mainly includes the following steps:

Feeding: Feed the plastic products to be processed into the feeding port of the crusher.
Crushing: After the plastic products pass through the feed port, they are crushed and crushed by the blades and rotors to form small particles.
Separation: The crushed plastic particles are sieved through a screen to separate particles of different sizes.
Collection: Collect and store separated plastic particles for subsequent processing or reuse.
During the entire working process, the plastic crusher crushes the plastic products through the rotation of the blades and rotors, and then separates them through the screen to finally obtain the required plastic particles.

Types of Plastic Shredders

Plastic crushers can be divided into many types according to their working principles and structural characteristics, including blade plastic crushers, knife ring plastic crushers, extrusion plastic crushers and other types and special purpose plastic crushers.

Blade Plastic Shredder

Blade plastic crusher is a common plastic crushing equipment. Its working principle is to cut plastic products into small particles through high-speed rotating blades. It usually includes a rotating blade and a fixed blade, and the plastic product is sandwiched between the two blades for cutting. This type of crusher is suitable for processing various types of plastic products and has the advantages of high crushing efficiency and uniform particle size.

Knife ring plastic crusher

Knife ring plastic crushers use annular blades for crushing, usually including a rotating knife ring and a fixed knife ring, and the plastic products are sandwiched between the two knife rings for crushing. This type of crusher is suitable for processing harder plastic products, such as plastic pipes, plastic sheets, etc. It has the characteristics of high crushing efficiency and low noise.

Extrusion plastic crusher

The extrusion plastic crusher is mainly used to process soft plastic products such as plastic films and plastic filaments. Its working principle is to squeeze the plastic products into granules through an extruder and then cut them with a blade. This type of crusher is suitable for the field of plastic recycling, and can reprocess waste plastic films and other products into particles for the production of recycled plastic products.

Other types and special purpose plastic crushers

In addition to the common types of plastic crushers mentioned above, there are also other types of plastic crushers with special purposes. For example, high-speed cycloidal shaft crushers, dual-shaft crushers, etc., are suitable for processing different types of plastic products or scenes with special uses based on different working principles and structural characteristics.

Plastic crusher working process

The workflow of a plastic crusher usually includes three main steps: raw material preparation, operation and operation, and maintenance and cleaning.

Raw material preparation

Collect plastic raw materials: First, you need to collect plastic raw materials to be processed. These raw materials can be waste plastic products, plastic particles or plastic films.
Classification and processing: Classify and process the collected plastic raw materials, such as removing impurities, cleaning, etc., to ensure that the quality of the raw materials meets the requirements.
Cutting and crushing: Cutting and crushing larger plastic raw materials to facilitate subsequent feeding and crushing operations.

Operation and Operation

Start the equipment: Add the processed plastic raw materials to the feed port of the plastic crusher, start the equipment, and ensure that all operations are normal.
Adjust parameters: According to the type and requirements of the plastic processed, adjust the parameters of the plastic crusher, such as rotation speed, feeding speed, etc., to ensure the crushing effect and production efficiency.
Monitor operation: During the operation of the equipment, regularly check the operating status of the equipment to ensure the normal operation of each component, and detect and handle abnormal situations in a timely manner.
Collecting products: Collect crushed plastic particles or powder and store them in designated containers or storage warehouses for subsequent processing or sales.

Maintenance and Cleaning

Regular maintenance: Regularly maintain the plastic crusher, including cleaning the equipment surface, lubricating the bearings, checking the electrical system, etc., to ensure the stable operation of the equipment.
Clean up residues: After the equipment stops running, clean up the plastic particles or powder remaining inside the equipment to prevent clogging and affecting the next production.
Safety inspection: Conduct regular equipment safety inspections to ensure the effectiveness of various safety devices and protective measures and ensure the safety of operators.
Through strict work processes and standardized operations, the normal operation and production efficiency of the plastic crusher can be guaranteed, while the service life of the equipment can be extended and the occurrence of failures and accidents can be reduced.

Plastic crusher buying guide

Plastic crusher is an important equipment investment. The correct purchase can improve production efficiency and ensure long-term stable operation of the equipment. The following are recommendations from the plastic crusher buying guide:

Use needs analysis

Before purchasing a plastic crusher, you first need to analyze your own usage needs, including the type of plastic processed, output requirements, crushing particle size requirements, etc., to determine the type and specifications of the equipment required.

Key factors to consider

  • Capacity and production capacity: Determine the required crusher capacity and production capacity based on production needs to ensure that the expected production volume can be met.
  • Power and energy efficiency: Considering the power and energy consumption of the equipment, choosing equipment that can be efficient and energy-saving will help reduce production costs.
  • Equipment quality and durability: Choosing equipment with good quality and durability can reduce failure rates and maintenance costs and improve production efficiency.
  • Safety and environmental protection requirements: Ensure that the equipment has complete safety protection devices and environmental protection measures, meets relevant safety standards and environmental protection requirements, and ensures production process safety and environmental protection.
  • Cost and budget: Choose cost-effective equipment based on your budget, and comprehensively consider factors such as the equipment’s price, performance, and maintenance costs.

Brand and supplier selection suggestions

Choosing well-known brands and reputable suppliers can provide more reliable equipment quality and after-sales service. It is recommended to choose Antecs’ plastic crusher. Antecs is a well-known brand in the field of plastic processing equipment. It has rich experience and advanced production technology. It provides various types and specifications of plastic crushers with excellent performance and stable quality, and has been widely recognized and praised.

The suggestions in the above purchasing guide can help users better choose a plastic crusher that suits their needs and ensure the effective use and long-term benefits of investment.
