The mobile scrap metal shredder is a diesel-hydraulic twin shaft shredding system designed for the on-site primary size reduction of bulky, loose and irregular metal waste. It combines a mobile chassis, feeding system, shredding chamber, discharge conveyor and centralized control in one movable unit.
Typical materials include prepared light scrap steel, scrap iron sheets, empty metal drums, appliance shells, aluminum profiles, fabrication offcuts, selected vehicle body panels and other metal waste suitable for low-speed twin shaft shredding.
Two counter-rotating cutter shafts operate at low speed and high torque, gripping, shearing and tearing the material into shorter, coarse and irregular pieces. The processed scrap becomes easier to convey, inspect, separate, transport or feed into downstream equipment.
When smaller and more consistent output is required, the shredded material can be transferred to a scrap metal crusher for secondary hammer crushing and screen-controlled size reduction. Primary shredding and hammer crushing are separate processing stages.
A magnetic separator may be installed above the discharge conveyor to recover exposed iron and steel from suitable mixed processed material. Clean, single-metal ferrous scrap may not require this separation stage.
After ferrous metal removal, screening and suitable material preparation, an eddy current separator may be used in a separate downstream process when conductive non-ferrous metals need to be recovered from non-conductive residues.
The mobile scrap metal shredder can be configured with a wheeled or crawler-type chassis according to the working site, relocation frequency, ground conditions and transportation requirements. It can reduce fixed installation work and allow scrap to be processed closer to the collection point.
Heavy solid shafts, thick steel beams, large castings, sealed containers, pressure vessels, batteries, fuel tanks, explosive items and unidentified hazardous materials require separate handling or another processing method.
A mobile scrap metal shredder combines the shredding unit with a movable chassis or transportable platform, but mobility does not change the basic material limits of the cutter system. The feed must still be evaluated by dimensions, thickness, density, composition and hazardous components. Moving the machine closer to the scrap can reduce internal transport, but it does not make every metal suitable for direct shredding.
A trailer-mounted or wheeled unit is generally moved between prepared work areas and may require towing, leveling and external loading equipment. A tracked unit can reposition within a suitable site but adds chassis weight, hydraulic systems and maintenance requirements. The travel method, road limits, transport dimensions, ground bearing capacity and lifting conditions should be confirmed before the mobile arrangement is selected.
Diesel-hydraulic drive can support sites without a stable grid connection, while electric drive may offer simpler integration where adequate power is available. Fuel supply, local voltage, starting load, hydraulic cooling, ambient temperature, operating hours, noise restrictions and maintenance resources affect the final drive choice. Drive type does not determine cutter suitability or guaranteed capacity by itself.
The complete mobile system may require an excavator, grapple, feed hopper, discharge conveyor, magnetic separator or collection containers. Feeding height, discharge direction, conveyor folding, transport locks and maintenance access should be included in the layout. Dust collection must be evaluated from the material and cannot be assumed to fit every mobile chassis.
Actual throughput depends on material density, dimensions, cutter configuration, loading consistency, reverse frequency and discharge handling. Please provide material photos, maximum size, individual weight, hourly target, required output, number of relocation sites, transport distance, available power, loading machine and downstream process before quotation.
The Haoxing Mobile Shredder operates on the dual-shaft shear shredding principle. The entire system is powered by an onboard diesel engine, which drives a hydraulic system to actuate all core working components, enabling efficient size reduction and primary magnetic separation. The detailed process is as follows:
Power generation and transmission: The onboard high-performance diesel engine drives a hydraulic pump to generate high-pressure hydraulic fluid. This fluid is distributed through a control valve manifold to power the shredding chamber, discharge conveyor, magnetic drum and optional crawler undercarriage, delivering stable power to all core functions.
Material feeding: Waste material is loaded into the feed hopper by a hydraulic feeding device, such as a grapple or tipping hopper, or by manual feeding. The wide feed opening can handle large, bulky and irregular materials.
Dual-shaft shear shredding: Inside the shredding chamber, two parallel cutter shafts rotate in opposite directions at low speed and high torque, driven by hydraulic motors. Heavy-duty alloy blades arranged in an interlocking pattern apply shearing, tearing and compressive forces to the material. The material is continuously reduced into smaller strips or chunks until it passes through the blade clearance and is discharged from the bottom.
Material conveying and magnetic separation: Shredded material falls onto the discharge conveyor belt and is transported toward the rear. As it moves, the material passes beneath the onboard magnetic separator. Ferrous materials such as iron, steel and nails are attracted by the magnetic field and discharged into a dedicated ferrous collection area, while non-magnetic materials continue to the end of the conveyor.
Mobility and relocation: When relocation is required, the operator can use the hydraulic travel system to move the crawler or tire chassis to a new work site. Hydraulic support legs can stabilize the machine during operation, supporting safer and more stable shredding work.
Integrated all-in-one design, no site preparation required: The integrated unit reduces the infrastructure and installation work required for separate components. No concrete foundation is needed, and material transportation between fixed processing sites can be reduced, helping save setup time, labor and overall project cost.
Compact layout and flexible configuration: The mobile shredder integrates the shredding chamber, discharge conveyor, magnetic separator, onboard diesel engine or electric motor, gearbox and control panel onto one chassis. The compact layout improves site flexibility and allows the unit to work independently or connect with other equipment when needed.
High mobility and strong site adaptability: With good ground clearance and a compact body design, the mobile shredder is suitable for relocation between different working sites. The chassis can handle common recycling yard conditions and helps improve layout flexibility during on-site processing.
Multiple mobility options for quick setup: Tire-mounted and crawler-mounted options are available according to site conditions and mobility requirements. Onboard hydraulic support legs can help stabilize the machine after arrival, supporting quick setup and operation.
Built-in diesel power and hydraulic drive: Powered by an onboard diesel engine, the unit can work in sites where external electricity is limited. The hydraulic drive system provides stable power for shredding, conveying and auxiliary movement, supporting flexible on-site material processing.
