Against the background of global circular economy promotion and carbon reduction goals, the waste electrical and electronic equipment (WEEE) recycling industry has become a key sector driving sustainable development. End-of-life refrigerators, as a major category of household appliances, contain a variety of valuable resources including ferrous and non-ferrous metals, plastics and polyurethane foam, as well as controlled hazardous substances such as refrigerants and compressor oil. Proper dismantling and recycling of these units is critical to preventing environmental pollution and maximizing resource recovery.
Traditional refrigerator dismantling processes, which rely heavily on manual operations, face multiple inherent limitations. Manual handling of refrigerators poses significant safety risks, including exposure to hazardous refrigerants, compressor explosion hazards and physical injury risks. The manual sorting of mixed materials is inefficient, labor-intensive and prone to low purity rates of recovered materials. In addition, unregulated manual dismantling often leads to improper release of refrigerants and inadequate treatment of foam insulation, resulting in environmental pollution and non-compliance with global emission standards.
As global environmental regulations become increasingly stringent and the demand for high-purity recycled materials continues to rise, there is a growing need for automated, compliant and integrated refrigerator dismantling solutions.

The Dual-Shaft Shredder is the core equipment of the pre-shredding stage. It reduces the volume of waste refrigerators by shredding intact units or components into smaller pieces. The low-speed, high-torque operation of the shredder ensures effective decomposition of refrigerator shells, insulation and other components, producing a uniform material stream suitable for subsequent processing. The shredder is designed to handle the mixed materials found in waste refrigerators, including metal, plastic and foam, with minimal risk of jamming or damage.
Belt Conveyors are used to transport shredded materials from the pre-shredding stage to the next processing stage. They provide continuous, controlled feeding to ensure a steady flow of material through the line, preventing bottlenecks and optimizing processing efficiency.
The pre-shredded material is further processed in the crushing and screening unit to achieve uniform particle size, which is essential for efficient subsequent sorting operations.
The Heavy-Duty Horizontal Crusher is used to further reduce the size of pre-shredded refrigerator materials. It is designed to handle mixed materials, including metal, plastic and foam, producing a homogenized material stream with consistent particle size. The crusher’s robust construction ensures reliable operation under continuous, high-load conditions, making it suitable for the demanding requirements of WEEE recycling.
The Vibrating Screen is used to classify crushed materials by particle size. It separates oversize materials for re-crushing and ensures that the material entering the sorting stage is within the optimal size range for accurate separation. The screen is designed to handle the mixed, multi-component material stream from the crusher, with adjustable settings to accommodate different material characteristics and sorting requirements.
This unit is designed to separate the mixed crushed materials into individual components, including ferrous metals, non-ferrous metals, plastics, foam and other recyclable materials. It combines multiple sorting technologies to achieve high-purity separation of different materials.
The Drum Magnetic Separator is used to separate ferrous metals from the mixed material stream. It attracts iron and steel components, enabling their recovery and preventing interference with subsequent non-ferrous metal sorting processes. The separator is designed to handle the high-volume material stream from the crusher, ensuring efficient removal of ferrous metals.
