Refrigerator Shredder Machine Fridge Crusher Refrigerator Recycling Plant For Furniture Refrigerator

A refrigerator shredder is an industrial device designed specifically for discarded refrigerators, freezers, and other large appliances. It uses the shearing, tearing, and squeezing action of dual-axis rotating blades to break the entire refrigerator into uniform, small pieces (typically flake-like particles, 200-300mm in size). As the first step in the waste appliance recycling production line, its core goal is to reduce the volume of large items, destroy their structure, and disperse their materials, facilitating subsequent sorting and recycling.

Working Principle

Power and Drive System

Powered by a dual planetary reducer, it features a low speed (typically less than 50 rpm) and high torque design, ensuring strong tearing force against hard materials such as metal frames and compressors.

The main shaft is forged from high-strength alloy steel and subjected to multiple heat treatments, providing strong impact resistance and adaptability to the complex internal structure of refrigerators.

Shredding Mechanism

Dual-Axis Shearing: The rotating and stationary blades on the two rotating axes intersect to create a shearing force that cuts through materials such as refrigerator casings and insulation. Tearing Action: The blade tip contacts the cylindrical surface of the spacer, tearing hard components (such as metal pipes and plastic brackets).
Crushing: The torque of the blade shaft crushes soft materials (such as foam and rubber), achieving a preliminary separation of mixed materials.

Intelligent Removal Device

Equipped with an automatic cleaning system, it removes foam, plastic, and other materials adhering to the chamber walls, preventing blockage and maintaining continuous operation.

Applicable Materials
Metals: Scrap iron, car hulls, bicycle frames, motorcycle frames, metal briquettes, paint cans, pre-painted steel tiles, cans.
Wood: Furniture scraps, miscellaneous wood, branches, boards, wooden pallets, solid wood, tree stumps.
Plastics: Pipes, films, woven bags, plastic barrels, mobile phone cases, discarded fuel tanks.
Household Waste: Sofas, mattresses, clothing, waste fabric, tires.
Industrial Solid Waste: Leather, fabric, circuit boards, wire rope, refrigerator, air conditioner, and washing machine casings.
Special Materials: Concrete blocks (requires construction waste treatment equipment), electronic waste (requires pollution prevention design).

Furniture shredder blade features:
Material and Craftsmanship:
Highly wear-resistant alloy steel: such as SKD-11, 42CrMo, and Cr12MoV, with a hardness of HRC58-62 and strong impact resistance.
Surface Treatment: Salt bath furnace quenching or vacuum furnace quenching improves wear resistance and service life.
Overlay Technology: Multi-layer overlay welding (single layer height ≤ 8mm) enhances blade hardness and reduces wear.
Structure and Specifications:
Cutter Roller Type: Dual-shaft or quad-shaft designs, with 3-12 claws to accommodate different material characteristics.
Connection: Hexagonal connection ensures uniform force distribution, and modular blades allow for independent replacement of individual blades for efficient maintenance.
Size Range: Diameter 200-500mm, thickness 20-55mm, with internal holes typically hexagonal or round (with keyway). Special Design:
Spiral cutter disc: Double rollers interlock with a gap of ≤0.5mm, precisely controlling the discharge particle size (1-5mm).
