Heavy-Duty Metal Shredder

Product Introduction

Scrap metal is money sitting idle on your yard. Bulky car bodies, tangled copper wire, pressed aluminum bales, and loose steel turnings cost a fortune to transport and process. Impact crushers create sparks and dust hazards, while undersized shredders choke on tough ductile metals. You need a machine that chews through metal, not fights it.

Introducing our Heavy-Duty Twin-Shaft Metal Shredder, purpose-engineered to rip apart aluminum profiles, steel drums, copper radiators, cast iron, and even complete engines. Low-speed, high-torque shearing action tears metal apart without sparks, without excessive heat, and without the violent kickback of high-speed mills. One machine to reduce volume, liberate materials, and prepare clean, dense scrap for smelting or sale.

Product Features

Twin-Shaft High-Torque Shearing Two counter-rotating shafts drive thick, hardened alloy steel blades, generating enormous shearing force at low speed. This design rips through ductile metals like aluminum, copper, and mild steel without sparks, ignition risk, or material bridging. The result: safe, controlled, and continuous metal reduction.

Intelligent Anti-Jam & Auto-Reverse When tough tramp metals or overloads are detected, the PLC instantly triggers an automatic reverse and re-grind cycle. The shafts counter-rotate to clear the obstruction, then resume forward motion. No manual intervention, no bent shafts, no hours of downtime prying out stuck lumps.

Ultra-Durable, Re-Sharpenable Blades Blades are machined from high-carbon, high-chromium tool steel (H13/D2 variants), through-hardened for extreme wear resistance and toughness. Thick cutting edges accept multiple re-sharpening and re-spacing cycles. Quick-change access covers and segmental blade design minimize maintenance time and cost.

Controlled Output Sizing Whether you need palm-sized output for re-smelting, or fine chips for further separation, the interchangeable sizing screens and adjustable blade gap give you complete command over particle dimensions. Hydraulic screen lifters make changes fast and safe.

Safety-First Design & PLC Intelligence Full enclosure guards, safety interlocks on access doors, and emergency stops come as standard. The PLC system monitors shaft speeds, motor current, and hydraulic pressure in real time, shutting down or reversing automatically when anomalies occur. Sparks and dust are inherently suppressed by the low-speed cutting action.

Applicable Material

Metal Materials We Shred

Aluminum Scrap: UBC cans, aluminum profiles, sheets, castings, extrusion butts, and baled aluminum. Shreds clean for remelting or further sorting.
Copper & Radiators: Copper wire, cables, air conditioner radiators (drained), and electric motors. Low-speed shearing liberates copper from insulation and steel casings.
Light Steel & Tinplate: Steel drums, stamping scrap, steel turnings, paint cans, tinplate packaging, and household appliances.
Cast Iron & Heavy Parts: Engine blocks, gearbox housings, brake drums, and cast iron pipes. Crushed into manageable chunks for foundry feed.
Automotive Scrap: End-of-life vehicle parts, body shells (fluids removed), bumpers, and automotive subframes. Reduces volume dramatically for transport.
WEEE & Mixed Scrap: Electronic waste casings, white goods, mixed metal-plastic composites. Prepares feedstock for downstream separation and recovery.

FAQ

Will shredding metals create sparks or fire hazards? Our twin-shaft shredders operate at very low RPM (10–25 rpm), which inherently avoids spark generation. The cutting action shears rather than impacts. For extra safety, we can integrate an inerting or fire suppression system when processing flammable materials like magnesium turnings.

Can the machine handle contaminants like rubber and plastic on metal scrap? Yes. The shredder processes mixed metal-plastic composites without issue. Downstream separation systems (magnetic, eddy current, or density) can then cleanly separate the fractions.

How long do the blades last when shredding heavy steel? Blade life varies widely with material abrasiveness and thickness. For mixed automotive scrap, expect 600–1,200 hours before re-sharpening. With proper maintenance, one set of blades can be re-sharpened 5–8 times.

Can I adjust the output size for different metals? Absolutely. The hydraulic screen cradle allows screen changes in under 15 minutes. We supply a range of screens (20mm–80mm) to match your specific downstream process — whether you need coarse shred for sorting or fine chips for direct melting.

Do you offer installation and training support for overseas buyers? Yes. We provide full engineering drawings, 3D installation models, and step-by-step commissioning videos. On-site assembly, startup, and operator training by our engineers can also be arranged.
