Waste Refrigerator Recycling Line

Waste Refrigerator Recycling Line

The Waste Refrigerator Recycling Line by Suny Group is a fully automated solution designed for efficient dismantling and recycling of end-of-life refrigerators. It integrates shredding, separation, and sorting technologies to recover steel, copper, aluminum, and plastics. With stable performance and high recovery rates, the line ensures safe operation, environmental compliance, and maximum resource utilization.

The Waste Refrigerator Recycling Line by Suny Group is a highly efficient and environmentally friendly solution designed for the recycling of end-of-life refrigerators and cooling appliances. The line features a high level of automation, stable operation, and low labor requirements, making it suitable for large-scale recycling facilities. It complies with environmental standards and maximizes the recovery of valuable materials.

In the working process, waste refrigerators are first fed into the system and undergo safe pretreatment, including degassing and component removal to ensure compliant handling. The units are then shredded into uniform pieces by a heavy-duty shredder. Advanced magnetic separation, eddy current separation, and air separation systems are used to sort different materials accurately. Foam insulation is efficiently separated and collected, while dust and emissions are controlled through a dedicated filtration system.

The final output is a major advantage of this recycling line. Clean steel, copper, and aluminum are discharged separately with high purity, suitable for direct reuse or smelting. Recovered plastics and foam materials are collected efficiently, increasing overall recycling value and profitability.

Workflow

1. When the waste refrigerator (or freezer) is on the unpowered drum, disassemble it manually and remove the plastic and glass from the box;

2. According to different types of refrigerants, refrigerant recovery devices are used to classify and recover refrigerants. Remove the compressor and condenser, etc.
3. The whole machine enters a double-shaft shredder for shredding and preliminary crushing.
4. The materials enter the hammer crusher, and are crushed for the second time through crushing and kneading by the crusher.

5. At the same time of secondary crushing, part of polyurethane foam will be separated into foam separator by air separation. Heavy materials such as plastic and metal enter the belt conveyor.

6. Materials crushed by plastic and metal are separated by magnetic separation on the belt, and then enter eddy current separation.
7. Non-ferrous metals, such as copper and aluminum, are separated by eddy current, and plastic and foam materials are transported to the airflow separation system through belts to separate pure plastic and foam. Polyurethane foam is compressed into blocks by a foam crusher.
