Plastic Crusher: In-Depth Analysis of Technical Details and Key Points in Plastic Recycling

In the field of plastic recycling and resource regeneration, the plastic crusher is a core equipment for realizing the efficient disposal and recycling of plastic waste. This article will deeply analyze the technical details, structural composition, working principle and advantages of plastic crushers, providing professional reference for practitioners in the plastic recycling industry.

1. Overview of Plastic Crushers

A plastic crusher is a specialized crushing device developed for the plastic recycling industry. It can crush various plastic products such as mineral water bottles, PET bottles, oil bottles, gasoline bottles, plastic barrels, plastic pallets, and plastic baskets, laying a foundation for plastic recycling and the production of recycled plastic pellets. It is a key equipment to promote the circular economy of plastics.

2. Core Structure and Professional Components

(1) Crushing Mechanism

• Alloy Cutting Tools: Made of ASTM standard high-strength alloy, they are distributed in a spiral or staggered manner, with excellent wear resistance and shearing force. When the tools are worn, they can be reused through coating and welding repair technologies, greatly reducing maintenance costs.

• Hexagonal Structural Design: The inner hole of the tool and the surface of the main shaft adopt a hexagonal design, so that the force on the tool is uniform, avoiding local wear or equipment failure, and ensuring long-term stable operation.

(2) Drive System

Equipped with a high-torque motor with a power range of 10-100HP (horsepower), it realizes a low-speed and high-torque operation mode, which can effectively avoid plastic entanglement or equipment jamming and improve crushing efficiency.

(3) Control System

Adopting a PLC intelligent control system that meets UL and CE electrical standards, it can automatically realize the start, stop, reverse and overload protection of the equipment, support unattended or remote control, and improve the safety and convenience of operation.

(4) Built-in Filter Screen Device

The equipment is equipped with a built-in filter screen device. During normal operation, it can separate materials and liquids, and effectively recover residual liquids in the bottle (such as the separation and recovery of residual gasoline after the gasoline bottle is broken). It meets EPA environmental compliance requirements and has both environmental protection and resource recovery value.

(5) Whole Machine Composition

The waste plastic crusher is composed of a crushing structure, a bracket, a recovery box and a trolley. The size of the industrial plastic crusher is determined by the type of material to be processed and the production capacity requirement. The processing capacity per unit time can reach 0.5-8 tons/h, and small equipment can meet the lightweight crushing needs of some scenarios.

3. Working Principle

When the waste plastic crusher is working, it realizes automatic feeding by extruding the raw materials. Its unique structural design prevents the cutter shaft and rotating cutter from entanglement or jamming when running at low speed and high torque, thereby improving production efficiency. It is suitable for crushing various plastic products.

4. Technical Advantages

1. Low Tool Maintenance Cost: The tool can be reused through coating and welding repair technologies after wear, reducing the cost of tool replacement.

2. Good Force Uniformity: The hexagonal design ensures that the tool is evenly stressed, prolonging the service life of the equipment.

3. Strong Adaptability: The thickness of the tool and the number of claws can be adjusted according to different plastic materials to meet diverse crushing needs.

4. High Degree of Intelligence: The PLC control system realizes automatic operation and reduces the cost of manual intervention.

5. Outstanding Flexibility: The equipment is small in size, easy to move, simple and safe to operate, and suitable for various operating scenarios.

5. Common Q&A

1. What plastic products can the plastic crusher handle?

It can handle various soft and hard plastic products such as mineral water bottles, PET bottles, oil bottles, gasoline bottles, plastic barrels, plastic pallets, plastic baskets, and waste plastic frames.

2. What is the function of the built-in filter screen device?

The filter screen device can separate materials and residual liquids during the crushing process. For example, the effective recovery of residual gasoline after the gasoline bottle is broken meets the North American resource recovery regulations and has both environmental protection and resource reuse value.

3. How to choose the model of plastic crusher according to requirements?

It needs to be selected based on factors such as the type of material to be processed, expected production capacity, and site conditions. If the processing volume is small and the site is limited, a small plastic crusher can be selected; if it is for large-scale industrial recycling, an industrial-grade equipment with large production capacity is required, and its performance parameters need to meet the relevant industry standards of ASTM.

The plastic crusher, with its advanced technical design, excellent performance and wide applicability, has become an indispensable core equipment in the plastic recycling industry. By choosing and using plastic crushers reasonably, it can not only improve the efficiency of plastic recycling, reduce environmental pollution, but also promote the development of circular economy and create more economic and social value for the industry.
