If you want to turn coarse rubber granules into fine, uniform and salable granules, a rubber granulator is the machine that does the fine reduction. It takes 10 to 15 mm granules from the rasper and brings them down to 1 to 4 mm, the size required for sports fields, tiles and molded products. The wear-resistant DC53 steel blades and the adjustable gap keep a consistent product, batch after batch.
A well-built rubber granulator means easy blade changes, interchangeable screens with different diameters and a stable throughput. With it, the final stage of your line becomes flexible: you change the screen and get exactly the fraction the customer asks for.

Key Advantages of a Tire Granulator
• Fine 1 to 4 mm granules, a rubber granulator turns 10 to 15 mm granules into fine, uniform particles, ready to sell for the final product.
• Wear-resistant DC53 blades, the DC53 steel blade keeps its edge for a long time, even when continuously processing abrasive rubber.
• Adjustable gap, the distance between blades is set to optimize yield and granule size.
• Easy blade changes, simple access to the tools shortens downtime for maintenance and blade replacement.
• Interchangeable screens, screens with different hole diameters allow flexible production of several fractions.
• Consistent product, the adjustable gap and the precise screens ensure a uniform particle size, batch after batch.
• Robust construction, the rotor and housing are sized for heavy, continuous duty with abrasive material.
• Key finishing stage, a rubber granulator is the machine that raises the value of the material, from coarse granules to a salable fine fraction.

Applications and Industries for 1-4 mm Rubber Granules
A rubber granulator is the finishing stage in the tire recycling line, the one that produces the highest-value fraction. The fine 1 to 4 mm granules are the base material for sports fields, running tracks, playgrounds and elastic paving, where they provide elasticity, cushioning and improved safety on impact. For a producer, a reliable granulator means a quality final product and returning customers.
Industrial shredding equipment must meet the safety requirements of the European Union; a rubber granulator delivered in Europe complies with the requirements of Directive 2006/42/EC on machinery. For integration into a complete line, see also the complete solutions by industry.
The granules produced by a rubber granulator go into rubber tiles and mats for fitness rooms, into cushioning layers and into molded products that partially replace raw rubber. If the fraction is ground further into fine powder, it ends up in modified asphalt for roads and in regenerated rubber. For an operator, the ability to deliver several particle sizes from the same machine, just by changing the screen, opens up a wide range of products.
As demand for safe sports surfaces and durable construction materials grows, fine, clean and uniform granules become a real commercial advantage. A rubber granulator with DC53 blades and precise screens ensures exactly this uniformity, turning an intermediate material into a salable raw material with a better margin, whatever final fraction you choose to produce.
The fine granulation stage is also the one that sets a cheap product apart from a premium one. The more uniform and clean the granules, the higher the selling price and the more demanding and better-paid the accessible markets. A well-adjusted rubber granulator is therefore the machine that decides the final margin of the entire line, which is why blade construction and screen precision matter enormously.
Compatible Materials
A rubber granulator works with clean rubber granules, coming from rasping, with no significant trace of steel. The better the input material is freed of metal and fiber, the cleaner the final granules and the less the blades wear. The machine is designed for continuous duty with abrasive material.
| Accepted material | Notes |
|---|---|
| Granules from the rasper | 10 to 15 mm material, steel-free |
| Rubber from car tires | The main source for clean granules |
| Rubber from truck tires | After complete steel separation |
| Clean industrial rubber | Rubber profiles and waste free of metal |
How It Works
The flow through a rubber granulator is continuous and focused on fine reduction and calibration:
1. The 10 to 15 mm granules, coming from the rasper, are picked up from the belt and fed evenly into the machine.
2. The rotor with DC53 blades reduces the rubber, with a gap set for the target size.
3. The fitted screen retains the oversized granules and returns them to the cutting zone until they reach the required fraction.
4. The 1 to 4 mm granules pass through the screen and are discharged toward screening, sorting and final collection.
5. By changing the screen, you quickly modify the output size for a different final product.
6. The fine material can be sent further on for grinding into rubber powder, if needed.
Oversized material is recirculated, so the granules stay uniform. A continuously monitored rubber granulator keeps a constant particle size and quickly brings a new operator to stable results, a real advantage in plants with staff turnover. Easy access to the blades makes edge changes fast and planned maintenance possible without long production stops.
Frequently Asked Questions
What does a rubber granulator do?
A rubber granulator is the fine reduction stage: it takes 10 to 15 mm granules from the rasper and turns them into fine 1 to 4 mm granules, the size required for sports fields, tiles and molded products. The adjustable gap and the interchangeable screens allow precise control of the fraction, and the fine material can be ground further into rubber powder.
Why are DC53 blades important?
Because processing rubber is abrasive and puts a heavy load on the edge. Wear-resistant DC53 steel keeps its edge longer, which means uniform granules over long periods, fewer blade changes and lower maintenance costs. A rubber granulator with quality blades delivers a consistent product, batch after batch.
Can I adjust the granule size?
Yes. The output size is set through the gap between the blades and through the interchangeable screens, with different hole diameters. So a single rubber granulator can produce several fractions, from larger granules for bases to fine granules for surfaces, without changing the machine, only the settings.
Is the delivered equipment new?
Yes. We deliver new, unused equipment, made to order, not reconditioned units. The build uses components from established suppliers, CE marked where applicable, and every machine goes through a full inspection before shipping. You receive the technical documentation and operating manuals in your language, for a commissioning without surprises.

How long does installation and commissioning take?
Transport, commissioning and operator training are included and carried out by a local team, in your language. Before shipping, the machine goes through a full inspection, so your unit becomes operational quickly, with no hidden installation costs.
Where does the granulator fit in the line?
After the rasper and steel separation. The primary shredder produces chips, the rasper reduces them to 10 to 15 mm and pulls out the steel, and the granulator brings them down to 1 to 4 mm. A rubber granulator works best with clean, metal-free material, which is why rasping and magnetic separation upstream are essential for the quality of the final granules and for blade life.
