The waste household appliance crushing and recycling line is mainly used for processed waste refrigerators, washing machines, air conditioners and other discarded home appliances. Through automatic crushing, multi-stage screening and composite separation processes, mixed materials are deeply disassembled and sorted. Equipped with magnetic separation, eddy current separation and air separation systems, it can efficiently recover iron, copper, aluminum, plastics, foam and other materials to realize classified recycling and resource reuse. With stable operation, perfect dust removal and high automation, the line greatly improves resource utilization and promotes the development of green circular economy.
The line is designed to handle the two main categories of end-of-life household appliance feedstock:
Small Scrap Household Appliances | Large Scrap Household Appliances |
Microwave ovens, rice cookers, toasters, electric fans, small kitchen appliances and other compact household electronics. | Refrigerators, washing machines, air conditioning units and other large-format household appliances containing significant metal and foam content. |
A large renewable resource recycling enterprise specializes in dismantling and processing mixed waste household appliances — primarily refrigerators, air conditioners and washing machines. The company required a complete waste home appliance crushing and recycling line to replace fragmented manual processes with automated centralized crushing and precise multi-material sorting.
Specific requirements included:
• Efficient separation of iron, copper, aluminum, plastic and foam into clean, separate output streams.
• Compliance with local environmental protection standards, including dust emission control.
• Full-automatic operation to reduce labor costs and enable high-volume continuous production.
• High recovered material purity and recycling value to maximize economic returns.
• Large-scale, scalable operation supporting sustainable resource recovery.
Challenge 1: Complex Bonded Material Composition |
Waste appliances contain metals, plastics, foam and sponge physically bonded together. Traditional single-process sorting equipment achieved incomplete separation with excessive impurities, resulting in low recovered material value and poor economic return. |
Challenge 2: Crusher Blockage and Uneven Particle Size |
Appliance shells combine soft plastics with hard metal components. Standard crushers blocked frequently and produced inconsistent fragment sizes, seriously degrading the effectiveness of downstream sorting and increasing downtime. |
Challenge 3: Manual Sorting Bottleneck |
The existing operation relied heavily on manual sorting — slow, expensive and incompatible with mass continuous production targets. Labor costs were high and output quality was inconsistent. |
Challenge 4: Environmental Non-Compliance (Dust Emissions) |
The crushing process generated large volumes of airborne dust and light floating debris. Without a complete dust removal and collection system, the facility repeatedly failed local environmental inspection. |
Challenge 5: Inability to Separate Non-Ferrous Metals |
Existing equipment could not accurately separate copper and aluminum from other non-ferrous and non-metallic materials, causing significant resource waste and reducing overall recycling revenue. |
Combined with the material characteristics and working conditions of waste home appliances, we provided an integrated customized crushing and recycling solution.
Equipped with a special household appliance crusher, it adopts composite shearing crushing technology to evenly crush complex appliance components and effectively avoid material blockage.
Integrated with vibrating screening, magnetic separation, eddy current separation and air separation system, it realizes multi-stage separation of iron, non-ferrous metals, plastics, foam and light impurities, greatly improving material purity and recycling rate.
Adopting intelligent PLC control system, the whole line operates fully automatically, reducing manual intervention and improving production efficiency and stability.
Equipped with pulse dust removal and light material collection device, it realizes closed dust treatment and environmentally friendly production in line with emission standards.
Key components are made of high-wear-resistant materials with low failure rate and simple maintenance. It helps customers reduce costs, increase efficiency, maximize resource value and promote the sustainable development of circular economy.
