Scrap Oil Drum and Paint Bucket Shredding and Sorting Line: Complete Solutions from Hazardous Waste to Clean Metal Granules
Waste oil drums, paint buckets, and chemical containers are classified as hazardous waste. They contain residual oil, paint, and chemicals, and their robust, bulky structure makes manual dismantling inefficient and dangerous. Landfilling or open stacking causes severe environmental pollution and resource waste. Haoxing Machinery provides complete scrap oil drum and paint bucket shredding and sorting lines, integrating dual-shaft shredders, scrap steel hammer mills, magnetic separators, eddy current separators, chain plate conveyors, belt conveyors, and pulse dust collectors. The line employs a "coarse shredding + fine crushing + multi-stage sorting" process within a fully enclosed, negative-pressure environment to safely pulverize contaminated drums into clean metal granules (3–20 mm). Paint, rust, oil residues, and non-metallic impurities are effectively separated, enabling both the harmless treatment of hazardous waste and the high-value recovery of ferrous and non-ferrous metals.
1. Core Process Flow for Oil Drums and Paint Buckets
The line incorporates specialized safety designs to address the flammability and liquid residue of drum feedstock. A typical flow is as follows:
Waste Oil Drums / Paint Buckets → Chain Plate Conveyor (Feeding) → Dual-Shaft Shredder (Coarse Shredding) → Belt Conveyor (Transfer) → Scrap Steel Crusher (Hammer Milling and Densifying) → Belt Conveyor (Discharge) → Magnetic Separator (Ferrous Purification) → Eddy Current Separator (Non-Ferrous Recovery) → Dust Collection System (Explosion-Proof Purification) → Clean Metal Granules
2. Equipment Functions in Detail
1. Feeding: Chain Plate Conveyor
Function: Smoothly transports whole or flattened drums to the dual-shaft shredder inlet.
Features: Heavy-duty slat construction resists impact and abrasion. Variable frequency drive adjusts feed speed automatically to prevent bridging. Customizable for horizontal or inclined layouts.
2. Coarse Shredding: Dual-Shaft Shredder
Function: Tears whole drums into strips or flat pieces, preparing material for fine grinding.
Features: Two counter-rotating shafts deliver high torque at low speed. Blades made from high-alloy wear-resistant steel with four indexable cutting edges. The shredding action destroys drum integrity and preliminarily strips paint and coatings. Explosion-proof motors and sealed construction ensure safe processing of oily feedstock.
3. Fine Grinding: Scrap Steel Crusher (Hammer Mill)
Function: Pulverizes shredded strips into dense, spherical granules (3–20 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, rust, and coatings are stripped off and pulverized during crushing. Housing fabricated from 20–50 mm manganese steel plate with hydraulic lid opener for easy maintenance.
4. Magnetic Separation: Magnetic Separator
Function: Separates ferrous metals (steel, iron) from non-magnetic materials (copper, aluminum, paint flakes, plastics).
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%.
5. Non-Ferrous Separation: Eddy Current Separator
Function: Recovers valuable non-ferrous metals (copper, aluminum) 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%.
6. Material Handling: Belt Conveyors
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.
7. Environmental and Safety Control: Pulse Jet Baghouse Dust Collector
Function: Captures airborne dust, paint powder, and oily light fluff generated during shredding and conveying. Ensures safe, compliant emissions.
Features: Sealed negative-pressure ducting with explosion venting. Pulse-jet cleaning maintains high filtration efficiency. Treated exhaust is safely vented, meeting hazardous waste treatment environmental standards.
3. Adaptability to Different Drum Types
Haoxing oil drum and paint bucket processing lines handle various metal containers and can be configured accordingly:
Waste Oil Drums / Paint Buckets: Standard configuration with dual-shaft shredder, hammer mill, and magnetic separator. Capacity: 3–6 t/h.
200L Heavy Drums / Chemical Drums: Add a pre-flattening stage or use a higher-power dual-shaft shredder for direct processing.
Composite Drums with Copper/Aluminum: Include an eddy current separator for multi-metal recovery.
High Residual Oil Content: Integrate online drying or secondary washing to ensure fire-safe operation.
