Bulky Waste Shredder, or bulky waste shredder, is an efficient crushing equipment specially used to process solid waste with large volume, complex structure and difficult transportation. With the acceleration of urbanization and the improvement of residents' living standards, the amount of large waste generated has increased year by year, such as waste furniture, mattresses, cabinets, sofas, electrical appliance housings, large plastic parts, wooden components, etc. These wastes are not suitable for direct entry into traditional waste treatment systems due to their large size and difficulty in transportation, so they need to be pre-processed with the help of special equipment. The emergence of Bulky Waste Shredder has effectively solved this problem.

The equipment breaks large waste into smaller pieces through the low-speed and high-torque shearing method of high-strength wear-resistant tools, greatly reducing the volume of waste and facilitating subsequent classification, transportation, incineration or resource recycling. Its structure generally adopts a dual-axis or single-axis design, equipped with an automatic reversing function to prevent material jamming, and the control system is mostly PLC intelligent control, which can realize automatic operation and fault alarm.

Bulky Waste Shredder is widely used in many fields such as urban domestic waste treatment centers, renewable resource recycling enterprises, waste incineration power plants, and building materials recycling enterprises. The equipment can be equipped with different knives, screens, and conveying systems according to the type and scale of the processed materials, and has strong adaptability and flexibility. Some high-end models are also equipped with dust removal systems and noise control systems to meet environmental protection standards.

The use of this equipment can not only improve the processing efficiency of large-scale garbage, reduce the volume before landfill and incineration, and improve transportation efficiency, but also promote the separation and reuse of recyclable materials, and effectively promote the realization of the goal of solid waste resource utilization and harmless treatment.

Bulky Waste Shredder is an indispensable and important equipment in the modern solid waste treatment system. Its continuous technological advancement and application expansion will provide strong support for building a resource-saving and environmentally friendly society.

Bulky Waste Shredder is a kind of equipment specially used for crushing large solid waste with large volume and complex structure. Its working principle is based on the "low-speed high-torque shear crushing" mechanism. It has the characteristics of high crushing efficiency, low energy consumption and strong adaptability. It is widely used in the field of urban solid waste treatment and resource recovery.

Its core structure usually includes feeding system, crushing system, drive system, control system and discharging system. The crushing system is generally composed of a double-axis or single-axis cutter roller, on which are equipped with multiple sets of high-strength alloy blades with good wear resistance and impact resistance. During the working process, large pieces of garbage are loaded into the feed port through conveying equipment or grab buckets, and then sent into the crushing chamber. The motor drives the cutter shaft to rotate slowly, and with the help of the mutual bite and shearing force between the cutters, the large volume of waste is torn, squeezed and sheared into smaller sizes.

During the crushing process, low-speed operation can effectively reduce the generation of noise and dust, while avoiding excessive wear and safety risks caused by high-speed rotation. Some equipment is equipped with a hydraulic drive system, which can achieve a stable output of greater torque to cope with complex structures of hard or elastic materials such as sofas, mattresses, and wooden cabinets. The system is also usually integrated with an intelligent control program (such as a PLC control system) that can automatically identify material blockages and control the automatic reversal of the knife shaft to eliminate the jamming phenomenon, thereby improving the stability and continuity of the equipment operation.

In order to meet the requirements of different materials and discharge sizes, Bulky Waste Shredder can be configured with different types of screen structures to screen materials that meet the specifications. The crushed fragments can be transported to downstream processes, such as magnetic separators to separate metals, or enter waste incinerators, landfills, compression balers and other further processing processes.

Bulky Waste Shredder effectively achieves the volume reduction and pretreatment of large pieces of garbage through the shearing and crushing principle of low speed and high torque. Its reliable mechanical structure and intelligent operating system make it an indispensable key equipment in modern solid waste resource treatment systems. With the improvement of environmental protection requirements and the growth of urban solid waste management needs, its application will become more and more extensive, and the technology will continue to upgrade.
