What is a twin shaft scrap metal shredder?

This industrial equipment, designed specifically for scrap metal shredding, utilizes a dual-shaft counter-rotating mechanism. High-strength blades shear and tear scrap metal into uniform, small pieces, facilitating subsequent metal recycling and resolving the problem of bulky and difficult-to-handle scrap metal.

Twin shaft shredder integrated into a full production line setup inside the manufacturing facility.

What materials can be processed?

Scrap sheet metal: such as discarded steel, iron, and aluminum alloy plates;
Metal profiles: including scrap angle steel, channel steel, steel pipes, and rebar;
Metal products: such as scrap metal components, old metal parts, cans, and metal tins;
Other scrap metal: such as scrap metal mesh, metal scraps, and metal shavings.

Samples of shredded output materials, including mixed metal scrap, wires, and electronic waste.

Working Principle

Raw Material Input: Scrap metal is placed in the machine’s feed port.
Dual-Shaft Drive: A reducer drives the two shafts to rotate relative to each other, with the cutters on each shaft operating synchronously.
Shearing and Crushing: The cutters engage each other, shearing, tearing, and squeezing the scrap metal to break it down.
Discharge Collection: The crushed metal fragments are discharged from the discharge port, completing the crushing process.

Advantages and Features

Shredding blades: Made of high-hardness alloy, they are wear-resistant and impact-resistant, with sharp cutting edges, high crushing efficiency, and long service life. Shredding blade specifications can be adjusted according to the raw material.
Case: Constructed of welded, thickened steel plates, the sturdy structure is highly resistant to deformation, capable of withstanding impact during crushing and effectively protecting internal components.
Speed reducer: Utilizes a well-known brand, high-quality speed reducer, offering high transmission efficiency, stable operation, and low noise. The speed can be adjusted to suit different crushing requirements, adapting to the crushing needs of different raw materials.
Shaft: Crafted from high-strength alloy steel and tempered for high hardness and toughness, it resists bending and breaking, ensuring smooth operation and long-term stable operation.
