Double-shaft double-motor shredder

A metal shredder is a specialized device designed for coarse crushing of various large-volume and high-hardness scrap steel, scrap aluminum, etc. By crushing scrap metals, their bulk density is increased to facilitate transportation and recycling.

This equipment is widely used for shredding various waste metal materials such as oil drums, diesel drums, thin iron sheets, car shells, metal briquettes, and metal sheet scraps. The process of crushing solid waste mainly relies on the principle of “shearing and cutting”. The motor drives the reducer to transmit torque to the moving knife of the crusher through the knife roller shaft. The knife hook of the moving knife hooks the material and tearing it down. The blades of the opposite roller cut the solid waste like scissors. The crushed material and the pre-screened material are discharged from the bottom of the crusher.

I. Core Technical Characteristics
High-strength tool system
It adopts imported special alloy cutting tools and hexagonal shaft design. The tool surfacing repair technology can extend the service life by 3 to 5 times. It is particularly suitable for processing high-hardness metals such as car bodies and aluminum alloy profiles.
The double-axis interlaced knife roller layout crushes materials through the triple action of shearing, tearing and squeezing. The crushed metal fragments have uniform specifications, which is convenient for magnetic separation and sorting.
Power and structural optimization
Driven by dual motors and dual hard-toothed surface reducers, it achieves low speed (often below 30rpm) and high torque (up to tens of thousands of Newton-meters), capable of shredding medium and high-strength metals such as steel plates with a thickness of no more than 5mm and car engine hoods.
The frame is welded with high-strength steel plates, and the bearings are designed with four-layer seals, effectively resisting the impact of metal debris and liquid corrosion.
Ii. Intelligent Control System
PLC intelligent protection system
Equipped with Siemens PLC for real-time monitoring of current load, it automatically reverses to protect the motor in case of overload. It is also equipped with multiple safety mechanisms such as overload alarm and emergency braking.
Supports one-click start/stop/reverse operation, suitable for complex working conditions such as metal material entanglement, and reduces the need for manual intervention [[2]5.
Iii. Application Scenario Coverage
Multi-type metal processing capability
It can handle metal waste such as used car bodies, motorcycle frames, aluminum alloy doors and Windows, color steel tiles, and thin iron sheets (≤6mm). When equipped with magnetic separation equipment, it can produce qualified furnace materials for steel mills.
Compatible with the crushing of mixed materials (such as metal composite parts containing plastic/rubber), the blade combination can be adjusted to adapt to the characteristics of different materials.
