In-depth Analysis of Dual-shaft Shredder  machine Technology and Application

As a core equipment for waste recycling and material pretreatment, Yuxi dual-shaft shredders demonstrate unique value in material crushing scenarios across multiple industries, relying on their technical characteristics of low speed and high torque. The following is a professional analysis from the dimensions of structural principle, technical advantages, application scenarios, and model parameters.

1. Structure and Working Principle

Dual-shaft shredders adopt a structural design with independent dual-shaft drive. When the two shafts rotate in opposite directions, they extrude, shear, and tear materials. Its core components include:

•Shredding Mechanism: Blades made of special alloy steel (high-speed steel or tool steel) are staggered on the two main shafts. The blades are arranged in a spiral line, and the inner hole and the spindle surface adopt a hexagonal design to ensure uniform force.

•Transmission and Protection: The motor drives the cutter shaft through a reducer. The bearing is equipped with a six-layer sealing structure, which is effective in waterproofing and dustproofing. A PLC control system is adopted, with functions of start, stop, reverse, and overload automatic reverse, realizing automatic control.

During operation, materials enter the shredding chamber through the feeding conveyor, are crushed under the meshing action of the dual-shaft blades, and the finished products are discharged through the discharging conveyor. Materials that do not meet the standards are circulated and crushed in the chamber to ensure uniform crushing particle size.

2. Technical Advantages

    1.Crushing Capacity:

    It can handle high-toughness and high-viscosity materials such as electronic waste, plastic, metal, wood, and waste rubber. It can also operate efficiently when crushing materials with large thickness.

    2.Component Characteristics：       

    Blades are made of special alloy steel through special processes, featuring strong wear resistance, high strength, and repairability.

    The split-box design facilitates quick disassembly and maintenance of the cutter shaft (including blades, bearings, and sealing system).

    3.Intelligence and Reliability: PLC automatic control realizes unmanned operation. The equipment has passed the EU CE certification, and the motor is of a well-known brand, ensuring stable operation and adaptability to various working conditions.

3. Application Scenarios

Dual-shaft shredders are widely used in industrial waste recycling, medical recycling, electronic manufacturing, plate manufacturing, wood processing, domestic waste recycling, plastic recycling, tire recycling, papermaking, and other fields. The crushed materials can be directly recycled or further refined, contributing to the development of the circular economy.

4. Models and Parameters

The equipment provides a full range of models from YXS-600 to YXS-2600, with power ranging from 15×2 kW to 160×2 kW, and processing capacity ranging from 2-3 tons/hour to 25-60 tons/hour. The hopper size, equipment weight, and overall dimensions increase with the models to meet the production needs of different scales. Customized design is also supported according to material characteristics and production requirements.

With efficient crushing performance, wide material adaptability, and reliable operation, dual-shaft shredders have become a key equipment in modern waste resource utilization and material pretreatment, providing strong support for green production and circular economy construction in various industries.

Frequently Asked Questions

Q1: What can dual-shaft shredders handle in medical recycling?

A1: They can handle medical waste plastics, syringes, etc. The cutters are wear-resistant, sealed to prevent pollution, and the PLC system prevents material jamming.

Q2: What is the use of the six-layer sealed bearing in wood processing?

A2: It can prevent dust and water, avoid wood chips from damaging the bearing, and ensure the stable operation of the equipment during wood shredding.

Q3: What convenience does the split-box design of the dual-shaft shredder bring to equipment maintenance?

A3: The split-box design allows for convenient disassembly of the entire cutter shaft system (including the shaft, blades, bearings, and seals), greatly simplifying the maintenance process, shortening equipment inspection and repair time, and reducing maintenance difficulty and cost.

Q4: How do dual-shaft shredders efficiently shred tires?

A4: They rely on spiral-line cutters and hexagonal design for uniform force, dual-shaft independent drive for extrusion and feeding, and low speed with high torque to achieve efficient cutting.
