scrap metal shredders

Scrap Metal Shredders is an industrial equipment specially used to process various types of waste metals. It uses high-intensity mechanical force to shred scrapped cars, home appliances, metal products, etc. into uniform pieces for subsequent sorting and smelting and recycling. As a key equipment in the modern resource recycling industry, it has greatly improved the efficiency of metal recycling and promoted the development of the circular economy.

The equipment mainly serves:

Metal recycling station: processing various types of scrap steel, scrap copper, scrap aluminum and other metal waste;

Automobile dismantling plant: quickly decompose scrap car bodies to increase metal recovery rate;

Home appliance recycling companies: dismantle metal parts in waste refrigerators, washing machines and other electrical appliances;

Steel smelting plant: pre-treat scrap steel raw materials to reduce energy consumption costs.

Equipment structure and classification

Typical metal shredders are composed of a feeding system, a shredding knife box, a power system, a sorting device (magnetic separator, eddy current separator), an intelligent control system, etc. According to the structure, it can be divided into:

Double-axis shearing type: using staggered knife rollers to shear and shred materials, with strong applicability;

Four-axis crushing type: multi-stage crushing design, suitable for processing large-volume metal scraps;

Hammering type: crushing by high-speed hammer head, suitable for brittle metal materials.

Working principle

When working, the material enters the shredding chamber through the conveyor belt, and the high-strength alloy cutter is driven by the motor to rotate and shear. The metal is decomposed into regular fragments of 3-15cm under the action of strong shear force, and then the iron metal is separated by magnetic separation equipment, the eddy current separator recovers non-ferrous metals, and the remaining impurities are automatically sorted and discharged by the vibrating screen.

Environmental benefits

The equipment has significant environmental advantages:

Resource saving: every ton of scrap steel processed can reduce 1.6 tons of iron ore mining, saving 60% of smelting energy;

Emission reduction and carbon reduction: compared with primary metal production, it can reduce carbon dioxide emissions by 35%;

Space optimization: the volume of metal fragments is reduced by 80%, greatly reducing storage and transportation costs.

With the advancement of the “dual carbon” strategy, intelligent metal shredders are developing towards low energy consumption and high automation, providing key technical support for building a green circular economic system.
