Metallic drums and barrels — oil drums, paint buckets, milk powder cans, and chemical containers — are everywhere in industry and daily life. Made from thin steel sheet, they offer strength, stackability, and protection against air, light, and UV. But once empty, their hollow structure creates a disposal problem: large volume, high transport costs, and inefficient storage.

Size reduction is the answer. A metallic drum shredder compresses drums into compact steel scraps, cutting transport volume by up to 80% and unlocking value from scrap metal recovery.

Metallic drum shredder in drum or barrel recycling

Choosing the Right Machine

Double shaft shredder — The standard choice for most metal drums. Two interlocking rotors grip hollow containers firmly, preventing them from bouncing or rolling inside the chamber. This “biting” action delivers consistent, efficient shredding for typical drum sizes.

Four shaft shredder — For oversized drums or barrels that exceed double-shaft capacity. The additional rotors provide higher torque and larger feed opening, handling bulkier items without pre-cutting.

Granulator or crusher — For applications requiring finer output after primary shredding. A drum granulator processes shredded scraps into uniform chips, while a barrel crusher applies compressive force for volume reduction of thinner-walled containers.

Wanrooe offers shredders, granulators, and crushers configured for drum and barrel recycling. Whether you need primary size reduction, secondary refining, or a complete line, we match the machine to your material, throughput, and output requirements. Contact us for a tailored solution.

FAQ: Drum Shredding

Can a drum shredder handle drums with residual liquid?

Small amounts of residual content are manageable, but drums should be emptied and drained first. Excessive liquid can damage bearings, contaminate cutting blades, and create safety hazards. For heavily contaminated drums, pre-cleaning or a specialized liquid-tight shredder design is recommended.

What output size can I expect?

Double shaft shredders typically produce 50–150 mm scraps. For smaller chips, add a secondary granulator. Output size is controlled by screen selection and rotor speed.

Is shredded drum steel recyclable?

Yes. Clean steel scraps from shredded drums are accepted by most scrap metal recyclers. Removing paint, rubber seals, or plastic liners beforehand improves scrap grade and selling price.
