Metal shredder machine is a powerful industrial equipment used for the efficient and environmentally friendly processing of scrap metal materials. These machines play a crucial role in the metal recycling and waste management industry, as they are designed to reduce bulky and often sharp-edged metal waste into smaller, manageable pieces. This process makes it easier to transport and recycle scrap metal, contributing to resource conservation and reducing the environmental impact of metal waste disposal.

Advantages of the Scrap Metal Shredder Machine

Structural stability: the main body of the scrap metal shredder is made of high-quality steel plate processed and welded as a whole. After stress relief treatment, it ensures that the machine can remain stable even under long-time load.

• High-quality blades: the movable blades of the metal shredder machine are made of specialized special alloy tool steel. The knives undergo multiple processes including forging, precision machining, multiple heat treatments, and cryogenic freezing heat treatments to ensure superior cutting performance and long life of the blades. The hook mounting of the fixed knives optimizes the knife replacement function and improves the maintenance efficiency of the knives.
• Convenient Maintenance: The bearing housing of the twin-shaft metal shredder machine adopts the assembling and disassembling installation method. This type of installation allows users to quickly remove the moving knife, fixed knife, bearings, and other components. In addition, the unique sealing structure effectively isolates metal chips and grease, reducing pollution and damage to the equipment.
• Blades can be customized: Blades are available in 15mm, 20mm, 40mm, 50mm, 75mm, 100mm, and other thickness options for customers to choose from. Also, the thickness of the blades can be customized according to the needs of different materials. In addition, the number of knife jaws can be adjusted and replaced as needed to accommodate different types of waste and materials to be processed.

Working Principle of the Scrap Metal Shredder Machine

First, the staff feeds the scrap metal material to be processed into the feed system of the scrap metal shredder. At the core of the shredder, there is a pair of rotating blades. These blades are made of special alloy tool steel with sharp cutting edges.

Then the rotating blades of the cutting mechanism start cutting, tearing, and crushing the scrap metal. The rotation and movement of the blades are powered by high-torque motors to ensure an efficient cutting process. Scrap metal material is continuously cut, slashed, and shredded in the cutting mechanism, gradually becoming smaller pieces.

Finally, during the cutting and shredding process, the metal fragments are separated and a screening system separates the large scrap metal fragments from impurities.

Key Parts of the Scrap Metal Shredder

This double shaft metal shredder machine is mainly composed of a blade spindle, fixed knife, carrying box, box support, feeding system, power system, and electrical control system. The overall structure and design of the Scrap Metal Shredder are designed for durability, efficiency, and safety. This machine is designed to process a wide variety of scrap metal materials, whether it is small parts or large appliances and vehicles.

Application of Scrap Metal Shredder Machine

1. Scrap metal: metal scraps such as car shells, aluminum alloy, scrap cast aluminum parts, engine shells, lead, and steel plates with thicknesses below 15mm.
2. Waste home appliances and furniture: TV sets, washing machines, refrigerator shells, mattresses, sofas, tables, chairs and benches, and other waste home appliances and furniture.
3. Pipes and tubes: large pipes, fittings, PE pipes, and so on.
4. Waste tires: all kinds of car and truck tires and other waste tires.
5. Various hollow containers: plastic beverage cans, plastic drums, iron drums, packing boxes, packing barrels, etc.
6. Waste pallets: wooden pallets, plastic pallets, forklift pallets.
7. Garbage: kitchen garbage, domestic garbage, animal carcasses, RDF derivatives (combustible garbage fuel), medical garbage, biological orange rods, garden garbage, and other kinds of garbage.
8. Glue head material and paper mill strand: materials such as glue head material and paper mill discarded strand.

What Are the Types of Scrap Metal Shredder Machines?

Scrap metal shredders are categorized into two main types: single-shaft metal shredders and double-shaft metal shredders. These two types of machines have different capabilities and applications for processing different types and sizes of metal scrap.

Single-Shaft Scrap Metal Shredder

Working Principle: Single-shaft metal shredders have one main rotating shaft, usually fitted with sharp blades. Metal scrap is fed into the machine and then degraded into smaller pieces through a process of cutting and shredding by the rotating blades.

Application: Single shaft metal shredders are usually used to process light metal scraps such as scrap cables, cans, aluminum scrap, circuit boards, and some metal impurities. These machines are suitable for small scrap processing jobs and light scrap breakdowns.

Dual-Shaft Scrap Metal Shredder

Working principle: The Dual-Shaft Scrap Metal Shredder Machine has two rotating shafts, each equipped with sharp blades. Metal scrap is fed into the machine, where the two rotating shafts work in tandem to degrade it into smaller pieces through a more powerful cutting, tearing, and crushing process.

Application: Twin shaft metal shredders are suitable for processing heavier metal scrap including car shells, aluminum alloys, scrap metal parts, scrap machinery and equipment, scrap electrical appliances, and other industrial and commercial metal scrap. They are typically used for large-scale scrap processing jobs and heavy-duty scrap breakdowns.
