Understanding the Core Components of a Metal Shredder

A metal shredder is more than just a machine; it's a system. Here are its core components:

1. Main Unit:

Cutter Shaft: Single, dual, or quadruple shaft? Dual shafts are most common, processing metal by shearing and tearing.

Blades:Material (usually alloy steel), shape, number, and repairability. Blades are consumable parts, so their quality and durability are crucial.

Housing: Heavy-duty steel structure ensuring stable operation under high loads.

Power System:Typically an electric motor (electric) or diesel engine (for mobile or non-electric areas).

2. Feeding System:

Conveyor:Belt conveyor or chain conveyor for automatic, uniform feeding.

Feeding Method: Manual feeding, conveyor feeding, or steel grabber feeding.

3. Discharge System:

Conveyor: Transports the shredded material away.

Magnetic Separator (Optional but Important):Used to separate metallic and non-metallic impurities.

Dust Collection System (Environmental Requirements): Collects dust generated during the shredding process, meeting environmental standards.

4. Control System:

PLC Control: High degree of automation, capable of monitoring load, setting automatic reverse (anti-jamming), and fault alarms.

Electrical Cabinet: Core control unit.
