Tyres Rasper Machine

Rasper Machine for Tire Recycling

The tire rasper machine is a key piece of tire recycling equipment used between the primary shredder and rubber granulator.，The Rasper is a powerful intermediate shredding machine designed to transform rough tire shreds (TDS) into clean, wire-free rubber mulch. Positioned between the primary shredder and the granulator, it serves as the second-stage processing unit in a complete tire recycling line. With a throughput capacity of up to 6 tons per hour, the rasper combines precision engineering, high torque, and robust construction for continuous industrial operation.

Rasper Processing Capabilities

The rasper efficiently reduces TDS rough shreds into ¾ inch – 1 inch (≈ 20–25 mm) rubber mulch, preparing the material for fine granulation.
Its main rotor operates at a controlled speed, generating high torque that tears rubber apart without excessive heat build-up. The cutting chamber is lined with replaceable wear plates, extending equipment lifespan and minimizing downtime during maintenance.

Equipped with an intelligent recirculation system, the rasper ensures that oversized pieces are automatically redirected back into the cutting zone until the desired size is achieved. For larger systems or combined setups, rasper units can process up to 12 tons per hour depending on feedstock composition and screen size.
