End-of-Life Vehicles (ELVs), scrap motorcycles, bicycles, and other large-dimension metal scrap are vital sources of both ferrous and non-ferrous metals for recycling. These materials are bulky, structurally complex, and contain a mix of steel, iron, copper, aluminum, plastics, and rubber. Direct melting is inefficient and causes significant resource loss and environmental pollution. Haoxing Machinery provides complete ELV and bulky scrap metal shredding and sorting lines, integrating gantry shears, alligator shears, dual-shaft shredders, four-shaft shredders, scrap steel hammer mills, magnetic separators, eddy current separators, chain plate conveyors, belt conveyors, and pulse dust collectors. These systems efficiently perform primary shearing, coarse shredding, fine grinding, ferrous separation, and non-ferrous recovery, delivering high-density, high-purity scrap steel and non-ferrous metal granules that meet the strictest feedstock specifications for steel mills and secondary smelters.
The line features a modular design, flexibly configured based on material type, size, and throughput requirements. A typical flow is as follows:
ELVs / Motorcycles / Bicycles → Gantry Shear / Alligator Shear (Pre-Shearing) → Chain Plate Conveyor (Feeding) → Dual-Shaft / Four-Shaft Shredder (Coarse Shredding) → Scrap Steel Crusher (Hammer Milling & Densifying) → Belt Conveyor (Discharge) → Magnetic Separator (Ferrous Recovery) → Eddy Current Separator (Non-Ferrous Purification) → Dust Collection System (Environmental Control) → Clean Scrap Steel Granules + Non-Ferrous Metal Granules
Function: Cuts whole vehicles or oversized scrap (chassis beams, frames, ship plates, rails) into sizes suitable for downstream shredder feeding.
Features: Gantry shears feature large hoppers (up to 2-4 tons per batch) with automatic compression, feeding, and shearing cycles. Shearing forces range from 500 to 1250 tons with speeds of 10-12 strokes per minute. Alligator shears offer compact, flexible cutting for smaller profiles. Both are hydraulically driven, delivering high force with low noise, completely replacing flame cutting.
Function: Smoothly transports sheared or loose bulky scrap to the shredder inlet.
Features: Heavy-duty slat construction resists impact and abrasion from large metal pieces. Variable frequency drive adjusts feed speed automatically based on downstream load, preventing bridging and jamming. Customizable dimensions to fit site layout.
Function: Tears sheared or bulky scrap into strips or chunks, preparing material for fine grinding.
Features: Dual-shaft shredders use counter-rotating, low-speed, high-torque cutter shafts with high-alloy wear-resistant blades (four indexable cutting edges). Four-shaft shredders add two additional cutting shafts for higher reduction ratios and more uniform output. The shredding action effectively liberates plastics, rubber, and other non-metallic attachments, protecting downstream hammer mill hammers.
Function: Pulverizes pre-shredded material into dense, spherical granules (5-20 mm) via high-speed hammer impact and kneading.
Features: Rotor equipped with high-chromium alloy hammers. Material is repeatedly impacted and ground against manganese steel liners. Bottom screen grate controls output size (interchangeable). Paint and rust are stripped off during crushing. Housing fabricated from 20-50 mm manganese steel plate with hydraulic lid opener for easy maintenance.
Function: Separates ferrous metals (steel, iron) from non-magnetic materials (copper, aluminum, plastics, rubber).
Features: Permanent magnetic drum or self-cleaning overband design with field strength exceeding 8000 Gauss. Ferrous material is attracted and ejected into a clean pile, while non-magnetic material continues along the conveyor. Iron removal efficiency exceeds 99%.
Function: Recovers valuable non-ferrous metals (copper, aluminum, zinc) from magnetic tailings.
Features: High-frequency alternating magnetic fields induce repulsive eddy currents, ejecting non-ferrous particles away from non-metallic waste. Adjustable rotor speed accommodates different particle sizes. Separation purity ranges from 96% to 99%.
Function: Connects individual processing units, transporting material between stages.
Features: Tear-resistant nylon belts with self-aligning idlers and cleaning scrapers. Configurable for horizontal, inclined, or curved layouts.
Function: Captures airborne dust and light fluff generated during shredding and conveying.
Features: Sealed negative-pressure ducting connects all dust sources. Pulse-jet cleaning maintains high filtration efficiency. Treated exhaust is safely vented, ensuring a clean workshop environment.
Haoxing ELV and bulky scrap processing lines handle not only common carbon steel and cast iron but can also be configured for various metal streams:
Scrap Steel/Iron: Car bodies, motorcycle/bicycle frames, sheet metal, drums, offcuts, bales – standard configuration with hammer mill and magnetic separator.
Mixed Scrap Metal: Material containing copper, aluminum, zinc – add an eddy current separator for multi-metal recovery.
Light Gauge/Baled Scrap: Include a dual-shaft or four-shaft shredder for pre-conditioning, improving crusher efficiency and reducing hammer wear.
High-Hardness Alloy Steel/Ship Plate: Use gantry shear for pre-cutting, specify high-chromium hammers and thicker wear liners for enhanced durability.
