In the field of industrial solid waste and domestic waste treatment, the shredding of materials such as paint buckets, metal cans, and plastic containers is a key link in resource utilization and harmless disposal. The Yuxi Paint Bucket Shredder, as a new type of environmental protection equipment integrating the advantages of shredding and crushing, has become a core equipment in the solid waste treatment industry chain due to its efficient processing capacity for multi-material and multi-form materials.
The Yuxi Paint Bucket Shredder is an energy-saving and environment-friendly solid waste shredding equipment for both metals and non-metals, designed for the volume reduction and shredding of materials such as paint buckets, metal cans, and plastic buckets. It integrates the "shear tearing" principle of shredders and the "impact crushing" principle of crushers. Through the synergistic effect of dual rotating knife shafts, materials are shredded into uniformly sized particles, providing high-quality pretreatment for subsequent resource recycling or hazardous waste disposal.
2. Core Structure and Technical Specifications of the Equipment
1. Main Structural Composition
The equipment consists of key components such as a motor, reducer, rotating knife shaft, moving knife, fixed knife, frame, base, and machine shell:
• Rotating Knife Shaft: Adopts a dual-shaft design, and the moving knives on the knife shafts are arranged in a spiral line, ensuring that materials are uniformly sheared and torn in the crushing chamber, improving shredding efficiency.
• Knife System: Both moving and fixed knives are made of special alloy steel (high-speed steel or tool steel). After heat treatment, their hardness reaches above HRC60, featuring super wear resistance and cutting force, and can handle long-term shredding of different materials such as iron sheets, plastics, and rubber.
• Split Box Design: The knife shaft, blades, bearings, and sealing system adopt a modular split structure, which can be quickly disassembled and maintained, greatly reducing equipment downtime.

| Shredding Granularity | 5~80mm (adjustable) | The discharge granularity can be controlled by adjusting the gap between moving and fixed knives and replacing the screen, suitable for subsequent sorting, incineration and other processes |
| Motor Power | 11~82.5kW (depending on the model) | Power output is strongly related to processing capacity and material hardness (such as paint bucket wall thickness and material) |
| Knife Service | 800~1500 hours (depending on the material) | The special alloy steel material ensures durability when shredding metals, plastics and other materials |
| Protection Class | IP55 | Effectively resists dust and water vapor invasion in industrial environments, ensuring the safe and stable operation of the electrical system |
3. Equipment Performance Characteristics
1. Efficient Shredding with Multi-material Compatibility
Using the principle of composite shredding, it can handle simultaneously:
• Metal Category: Paint buckets, metal cans, scrapped electrical appliances (washing machine, refrigerator shells);
• Plastic Category: Plastic buckets, plastic bottles;
• Rubber and Others: Tires, car bumpers, roadblocks, circuit boards, domestic waste, waste from paper mills, etc.
It can achieve efficient shredding of materials of different materials and forms, with a volume reduction rate of more than 75%.
2. Reliability and Maintainability of Structural Design
• Hexagonal Force Design: The inner hole of the knife and the surface of the main shaft adopt a hexagonal structure, so that the knife is stressed evenly and avoids excessive local wear.
• Intelligent Overload Protection: The equipment is equipped with a torque monitoring and automatic reverse system. When unshreddable objects (such as hard metal blocks) enter the shredding chamber, it will automatically stop or reverse to prevent mechanical damage.
• Modular Operation and Maintenance: The split box design makes the disassembly and replacement of core components such as the knife shaft and bearings more convenient. Ordinary operation and maintenance personnel can operate after training.
3. Dual Guarantee of Environmental Protection and Safety
• The shredding chamber adopts a fully enclosed design, and is equipped with a negative pressure dust removal interface, which can be connected to a dust removal system to effectively control dust emission during the shredding process.
• For VOCs (volatile organic compounds) remaining in paint buckets, the equipment can be integrated with an activated carbon adsorption module to ensure that the exhaust gas meets the emission standards and meets the relevant requirements for air pollutant emission in European and American regions.
4. Application Scenarios and Industry Value
1. Solid Waste Treatment and Hazardous Waste Disposal Field
• For waste paint buckets with dangerous paint residues, after shredding, they can be sent to a hazardous waste incinerator for harmless disposal, meeting the pretreatment requirements of relevant European and American regions for hazardous waste storage pollution control.
• After general industrial solid waste (such as plastic buckets and metal cans) is shredded, metal and non-metal can be separated and recycled through processes such as magnetic separation and eddy current separation, improving resource utilization.
2. Metal Recycling Industry
After paint buckets, metal cans and other materials are shredded, their specific surface area increases, which facilitates melting and purification in subsequent smelting links, reduces smelting energy consumption, and improves metal recovery rate.
3. Inside Manufacturing and Industrial Enterprises
Waste paint buckets, plastic containers, etc. generated by industries such as chemical industry, machinery, and automobiles can be shredded onsite to achieve hazardous waste volume reduction and avoid compliance risks and transportation costs of hazardous waste outward transportation.
5. Equipment Selection and Operation and Maintenance Suggestions
1. Selection Basis
• Material Type: If metal paint buckets and thick-walled metal cans are the main materials, models with high torque and high knife hardness are preferred; if plastic and rubber materials account for a large proportion, configurations with high speed and large processing capacity can be emphasized.
• Processing Scale: For a daily processing capacity of less than 10 tons, a small single machine can be selected; for more than 10 tons, it is recommended to configure a complete production line of shredding + subsequent sorting.
• Environmental Requirements: In areas that need to be equipped with dust removal and waste gas treatment, select equipment models with integrated environmental protection interfaces.
2. Key Points of Operation and Maintenance
• Tool Maintenance: Regularly check the wear of the tool. When the wear amount exceeds 3mm, it is recommended to repair by surfacing or replace it to ensure the shredding efficiency.
• Lubrication Management: Add lithium-based grease to transmission components such as bearings and gears every 8 hours to prevent equipment failure due to insufficient lubrication.
• Safe Operation: Strictly implement the principle of "no-load start, uniform feeding", and it is strictly forbidden to send hard foreign objects (such as large stones, steel bars) into the shredding chamber.
