The Tire Rasper Machine is a high-efficiency secondary tire shredder used in modern tire recycling equipment systems. Installed between the primary tire shredder machine and rubber granulator, it processes pre-shredded tire chips (TDS) into uniform 10–30 mm rubber mulch.
As a critical intermediate machine, the tire rasper performs secondary size reduction and steel wire liberation, preparing materials for efficient magnetic separation and fine granulation. With robust structure, high torque design, and stable operation, it is widely used in waste tire recycling plants and rubber mulch production lines.
The tire rasper machine efficiently reduces tire shreds (TDS) into 20–30 mm rubber chips, which are ideal for rubber mulch and crumb rubber production. Its heavy-duty rotor generates high torque to tear rubber without excessive heat, ensuring consistent output size and long equipment lifespan.
During the rasping process, embedded steel wire is loosened and exposed, allowing downstream steel wire separator and magnetic separator systems to achieve higher separation efficiency.
Equipped with an intelligent recirculation system, oversized materials are automatically returned for further shredding until they meet the required size. Depending on system configuration, the tire rasper can handle up to 6–12 tons per hour, making it suitable for industrial-scale tire recycling operations.
Efficient Secondary Shredding and Steel Liberation Solution
Tire rasper machine is a high-performance machine often referred to as a secondary tire shredder in modern tire recycling equipment systems. It is designed to process pre-shredded tire material into 10–30 mm rubber mulch, while performing efficient steel wire liberation to prepare materials for downstream processing.
In a complete tire recycling line, the tire rasper is installed between the tire shredder machine and the rubber granulator. It plays a critical role in improving rubber purity and enabling efficient magnetic separation and fine processing.
Key Advantages:
Step-by-step process:
After the tire rasper stage, processed rubber chips are conveyed to the tire granulator for further size reduction into 1–5 mm crumb rubber. The tire rasper machine, as a secondary tire shredder, plays a critical role in stabilizing material size, improving rubber purity, and increasing the efficiency of downstream rubber granulator machines.
Scrap Tire Recycling – Produces high-quality rubber mulch for playground surfacing, sports flooring, and landscaping applications.
Crumb Rubber Production – Provides ideal feedstock for fine grinding into rubber granules and powder.
Industrial Recycling Systems – Suitable for processing rubber materials requiring secondary size reduction and precise output control.
The tire rasper machine is widely used in rubber mulch production, crumb rubber plants, and rubber powder processing systems. The processed 10–30 mm rubber chips are ideal for further grinding into rubber granules and powder, used in playground surfaces, athletic tracks, rubber tiles, and industrial rubber products.

The tire rasper is commonly referred to as a secondary tire shredder in tire recycling systems.
A tire shredder is used for primary size reduction of whole tires into large chips (50–300 mm), while a tire rasper functions as a secondary tire shredder to further reduce material into 10–30 mm rubber mulch. The rasper also improves steel wire liberation, making downstream separation more efficient.
The tire rasper machine offers a processing capacity from 300 kg/h to 6 tons per hour, depending on model and configuration. It produces uniform rubber chips (10–30 mm), suitable for further processing into crumb rubber and powder.
What is a tire rasper machine used for?
A tire rasper machine is used as a secondary tire shredder to reduce pre-shredded tire chips into uniform rubber mulch while improving steel wire liberation before granulation.
What is the difference between a tire rasper and a granulator?
A tire rasper produces 10–30 mm rubber chips, while a granulator reduces material into 1–5 mm crumb rubber for final processing.
How does the tire rasper improve steel separation?
It exposes embedded steel wire during shredding, allowing magnetic separators to remove steel more efficiently.
What is the price of a tire rasper machine?
The price depends on capacity and configuration. Contact us for a customized quote.
What size does a tire rasper produce?
Typically 10–30 mm rubber mulch, depending on screen size.
Is a tire rasper necessary in a tire recycling line?
Yes, the tire rasper ensures proper size reduction and improves steel wire liberation before granulation, making it essential for efficient recycling systems.
