The Bulky Waste Shredder is a powerful and efficient solution designed for processing large, oversized, and difficult-to-handle waste materials. It is widely used in municipal solid waste treatment, recycling centers, and industrial waste management facilities to reduce the volume of bulky items such as furniture, mattresses, wood pallets, and mixed waste.
With a robust low-speed high-torque design, the machine delivers strong cutting and tearing performance, ensuring stable operation even under heavy loads. Its durable blades and reinforced structure allow continuous shredding with minimal maintenance, while significantly reducing waste volume for easier transportation and further recycling.
√ Home appliances: refrigerator scrap, air conditioner used, washing machine scrap, TV shell, computer shell, etc.
√ Furniture: sofa, chair, desk, cabinets, door, mattress, bed, etc.
√ Other large and medium-sized waste.

The Bulky Waste Shredder works by using a powerful low-speed, high-torque cutting system to break down large and irregular waste materials into smaller, manageable pieces. Once bulky items such as furniture, mattresses, wood pallets, or mixed municipal waste are fed into the hopper, the dual rotating shafts equipped with strong hooks, blades, or cutters grab and tear the materials with intense force. As the materials are gradually shredded, the reduced-size output is discharged through the bottom outlet or conveyed to the next processing stage, such as sorting or further crushing.

The blade materials of a Double Shaft Shredder play a crucial role in determining its cutting efficiency, wear resistance, and service life. Typically, the shredder blades are made from high-strength alloy steel or tool steel, such as 9CrSi, M6V, Cr12MoV, H13, SKD-11, D2, or Cr12Mo1V1, etc. which offer excellent hardness and impact resistance.
Through advanced heat treatment processes like quenching and tempering, the blades achieve a perfect balance between toughness and durability, allowing them to withstand continuous heavy-duty shredding of metal scrap, plastics, tires, and other tough materials. In some high-end applications, surface hardening or coating technologies are also applied to further enhance wear resistance and extend blade lifespan.
With superior blade materials and precise manufacturing, the Double Shaft Shredder ensures stable cutting performance, reduced downtime, and long-term reliable operation in demanding recycling environments.

Building a recycling line with a Bulky Waste Shredder starts with designing a complete system based on the type, volume, and composition of incoming waste. As the core pre-treatment equipment, the bulky waste shredder is responsible for breaking down oversized materials such as furniture, mattresses, pallets, and mixed municipal waste into smaller, manageable pieces, creating ideal conditions for downstream processing.
A typical recycling line includes feeding systems, the Bulky Waste Shredder, conveying equipment, magnetic separation units, and sorting platforms. Depending on project requirements, additional equipment such as secondary crushers, air separation systems, or balers can be integrated to improve material purity and recovery efficiency.
With a properly configured recycling line, operators can significantly reduce waste volume, improve processing speed, and enhance resource recovery rates, making the entire waste management process more efficient, stable, and cost-effective.
