Secondary Shredders

The right size, every time. Finer, cleaner material ready for recovery.

Secondary shredders, such as raspers, take material from the primary shredder and liberate it into a finer, more consistent product. Built-in screening controls the output size: material stays in the cutting chamber until it’s small enough to pass through, so you get the size you need rather than just a smaller one.

Liberating material frees valuable fractions for recovery and gives you a cleaner product that’s ready for further processing or direct resale. A controlled output size also helps downstream equipment run more efficiently, and cleaner recovered material sells for a better price. Eilbeck’s secondary shredders work alongside our primary range, so you can source your whole line from the one supplier.

Raspers

Once the primary shredders have done the heavy lifting, Raspers cut and chop material down further into smaller, consistent pieces and liberate material for recovery, making it ready for screening, further processing, or resale. Built for the toughest feedstock including shredded passenger and truck tyres, TDF and RDF, wire-free rubber chips, e-scrap, mixed plastics, cables, and commercial waste.
