Tire Rasper Machine is a key equipment in modern tire recycling lines, designed for secondary shredding and steel wire liberation after primary crushing. It processes pre-shredded tire chips into uniform rubber pieces while effectively loosening embedded steel and fiber, making downstream separation and granulation more efficient.
With a heavy-duty rotor system, wear-resistant rasping teeth, and optimized screening design, the tire rasper ensures stable operation, high throughput, and consistent output size. It significantly improves rubber purity, reduces load on granulators, and enhances the overall efficiency of the entire tire recycling process.
Ideal for processing car tires, truck tires, and pre-cut OTR tire blocks, this machine is widely used in turnkey tire recycling plants worldwide, providing reliable performance and long service life for industrial-scale production.
Tire rasper is mainly used for crushing passenger car tires (PCR), truck and bus tires (TBR), off-the-road tires (OTR), bicycle tires, electric vehicle tires, motorcycle tires, agricultural and forestry machinery tires, engineering machinery tires, industrial vehicle tires, and other waste tires or other rubber products.
A Tire Rasper Machine is designed for the secondary shredding stage in a tire recycling line, where pre-cut or pre-shredded tire pieces are further reduced into rubber chips while liberating steel and fiber.
With its heavy-duty rasping rotor and screen system, the tire rasper efficiently breaks down tire chips into uniform rubber pieces, while allowing steel wire to be separated more easily in the next stage. This makes it a crucial machine for producing clean rubber material and improving the efficiency of downstream granulators and separators in the tire recycling process.

A Tire Rasper Machine plays a key role in the middle stage of a tire recycling line, positioned after the primary shredder and before the granulator.
After whole tires are pre-cut and shredded into chips, these rubber pieces still contain embedded steel wire and fiber. The tire rasper uses a high-torque rotor fitted with heavy rasping teeth and a replaceable screen to further break down the tire chips into smaller, uniform rubber pieces.
As the material passes through the rasping chamber, three important actions happen at the same time: The rubber is reduced to consistent chip size; The steel wire is loosened and exposed from the rubber; The material is prepared for efficient magnetic and fiber separation in the next stage.
Only rubber pieces small enough to pass through the screen are discharged, ensuring uniform output size. This controlled reduction process greatly improves the performance of downstream granulators and separation systems. By installing a tire rasper in the recycling line, operators can achieve better steel liberation, higher rubber purity, and smoother overall system operation.
Please watch the tire recycling machine working video below:
Processes pre-shredded tire chips into uniform rubber pieces, creating the ideal feedstock for granulators.
Rasping action exposes and loosens embedded steel wire, improving magnetic separation efficiency downstream.
Better steel and fiber release leads to cleaner rubber chips and higher-quality end products.
Replaceable screens ensure consistent discharge size and stable production quality.
Prepares material to the optimal size, lowering wear, energy use, and maintenance costs for fine grinding machines.
Built for high torque and continuous operation, suitable for tough tire materials like TBR (pre-cut).
Smooth material flow between shredder, rasper, and granulator increases throughput of the entire tire recycling line.
Durable structure, replaceable wear parts, and stable performance reduce downtime and service frequency.
As the core secondary shredding equipment between the primary shredder and the granulator, the tire rasper is responsible for reducing pre-shredded tire chips into uniform rubber pieces while effectively liberating embedded steel wire and fiber. Its rotor design, rasp teeth structure, screen size, and motor power directly determine the output size, steel separation efficiency, and overall system throughput.
The following technical parameters will help you evaluate the processing capacity, power configuration, and structural design of the tire rasper, so you can select the most suitable model for your tire recycling project.

Across modern tire recycling plants, the Tire Rasper Machine is a critical mid-stage machine that determines rubber chip quality and steel liberation efficiency. By delivering uniform output and preparing material for effective magnetic and fiber separation, the tire rasper significantly improves the performance of downstream granulators and the overall throughput of the recycling line. Kowloon Machinery has supplied tire raspers to multiple countries as part of complete tire recycling solutions, helping customers achieve higher rubber purity, lower wear costs, and stable continuous production.
Project 1: In 2026, installed a complete tire shredding line in Hungary for processing passenger and truck tires into rubber granules.
Project 2: In 2025, Czech customers purchased a complete tire recycling system used to handle large volumes of truck tires and car tires.
Project 3: In 2024, we provided a customized solution for our Turkish customers, transforming waste tires into reusable rubber materials for use in the construction applications.
Project 4: In 2026, for a tire recycling project in Zambia, the tire rasper was integrated as a standard secondary shredding unit.

In a full tire recycling system, the process typically follows: Tire Debeader → Tire Shredder → Tire Rasper → Rubber Granulator → Rubber Powder Grinder. The Tire Rasper plays a key role in reducing tire chips into uniform material while improving steel wire liberation for efficient separation and granulation.
As a professional manufacturer, Kowloon Machinery provide customized tire recycling solution depending on your requirements. Through the whole process of intelligent automation, waste tires resource system realizes the high-value recycling of tires: the tire bead wires are precisely stripped with a tire debeader. Tires are crushed into 50-100mm by a double-shaft shredder, and then crushed into 10-20mm by a tire rasper. The residual wire is completely separated by magnetic separations. Furthermore, the crushed rubber is processed into 1-7mm by a rubber granulator or 5-80 mesh by a rubber powder grinder. There is ladder type air separator to remove fiber impurities, and a pulse dust removal system to achieve clean production. The entire system is monitored by a plc intelligent control center and has fault warning and linkage control functions.
