Rubber Granulator is specially designed for rubber granulation in a tire recycling line as the third-stage process. After the first and second stages, waste tires are typically reduced into 10–20mm rubber chips, and the granulator further processes them into 1–7mm rubber crumb with high efficiency and stable performance. The final output size can be easily adjusted by changing different screen sizes, allowing flexible and customized production according to customer requirements.
Equipped with high-speed rotating knives, a wear-resistant cutting chamber, and an efficient screening system, the rubber granulator ensures consistent particle size, low energy consumption, and reliable long-term operation. It is widely used in the production of crumb rubber for applications such as rubber tiles, artificial turf infill, sports surfaces, and molded rubber products.
Kowloon Machinery offers customized tire recycling solutions based on your requirements for input tire type, production capacity, and output size. With extensive global project experience, we are committed to providing reliable equipment and complete solutions for efficient tire recycling. We warmly welcome your inquiry.
The Rubber Granulator is designed for fine size reduction in tire recycling lines and is suitable for processing a wide range of pre-treated tire materials after shredding and steel separation, such as 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.
As long as the material has been properly pre-shredded and most steel wire has been removed, the rubber granulator can further grind it into uniform rubber crumb with stable particle size.
This makes it an essential machine for producing high-quality crumb rubber used in sports surfaces, rubber tiles, molded products, and other recycled rubber applications.

Rubber Granulator is the third key stage in a tire recycling line, designed to convert pre-shredded rubber chips into fine, uniform rubber granules.
After tires are processed by primary shredding and secondary size reduction, the material is typically reduced to 10–20mm rubber chips with most steel already removed. These chips are then fed into the granulator’s cutting chamber, where high-speed rotating blades work together with stationary knives to shear and grind the material into smaller particles.
As the rubber is processed, it passes through a screen system that controls the final particle size. Only particles that meet the required dimensions (typically 1–7mm) can pass through, while larger pieces are continuously recirculated for further grinding.
This closed-loop grinding process ensures consistent output size, high efficiency, and stable production quality. It also enables the production of clean, uniform rubber granules suitable for applications such as rubber flooring, sports surfaces, and recycled rubber products.

The Rubber Granulator has been widely applied in tire recycling plants across global markets, serving as the final size-reduction stage to produce high-quality rubber granules with stable particle control and consistent output performance. With its reliable operation and flexible screen design, it plays a key role in helping customers achieve efficient and profitable rubber recycling 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, we installed a complete waste tire recycling line in Zambia, operating stably.
Project 5: In 2024, in a Australia project, the rubber granulator was integrated into a medium-capacity tire recycling line processing passenger and truck tires.
Project 6: In 2025, we supplied a small-scale fully automated rubber tire recycling line to a client in Mauritania, Africa, for the production of rubber powder.
In a full tire recycling system, the process typically follows: Tire Debeader → Tire Shredder → Tire Rasper → Rubber Granulator → Rubber Powder Grinder. The Rubber Granulator plays a key role in grinding rubber chips into uniform granules, ensuring precise particle size control for high-quality recycled rubber production.
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.

Rubber Granulator performs precision grinding of rubber chips into uniform granules, ensuring consistent particle size for downstream screening, fiber separation, and rubber crumb production.
Most Rubber Granulators produce granules between 1–7 mm, adjustable by changing the screen mesh to meet different rubber crumb specifications.
It processes pre-shredded tire chips, rubber blocks, and rubber pieces with minimal residual steel after rasper or magnetic separation.
Through high-speed cutting and controlled screening, the granulator helps release remaining steel and fiber, making subsequent separation more efficient and improving final rubber purity.
It is installed in the late stage of the tire recycling system, after the rasper and before the fiber separator and vibrating screen.
Capacity depends on rotor width, knife quantity, motor power, screen size, and the cleanliness of incoming rubber chips.
Yes. By replacing screens with different apertures, operators can easily control the final granule size without changing the machine structure.
Because it ensures uniform sizing, higher purity, and stable output, which are critical for producing market-grade rubber crumb used in mats, tracks, and molded products.
