Rubber Granulator

If your stock of used tyres grows every month and disposal costs become a net loss, an industrial rubber granulator turns that waste into a raw material with real commercial value. Available in four power variants (from 22 kW to 90 kW), this rubber granulator processes the raw material into uniform Φ5,5 mm granules, ready for resale or direct use in construction, road infrastructure and sports surfaces.

This rubber granulator integrates as the main stage in a complete recycling line , taking the material after primary shredding and ferrous metal separation. The X-configuration blade cutting system optimises the shearing force and reduces cutting resistance, which translates into lower energy consumption per tonne processed and an extended service life of the wear components.

Choosing a high-performance rubber granulator is essential for the profitability of the entire recycling operation. An undersized piece of equipment creates bottlenecks in the line, while an oversized rubber granulator consumes energy needlessly. That is why the range of four models (LD600 up to LD1200) covers the entire spectrum of needs — from independent operators with small volumes to recycling stations with continuous flow across three shifts.

Key Advantages of the Rubber Granulator for Tyre Recycling

• Scalable processing capacity — the rubber granulator is available from 300 kg/h for start-up operations, up to 1 200 kg/h for continuous industrial production across three shifts

• X-shaped cutting system with reduced resistance — the configuration of mobile and fixed blades distributes the shearing forces evenly, reducing energy consumption by 15–20% compared with conventional systems

• Textile fibre separation over 99% — in the rubber granulator, the fibres are removed during the granulation process, without additional dedicated equipment, and the granules meet the purity standards for premium applications

• Robust construction for heavy loads — the rubber granulator has a welded frame made of high-strength steel, a reinforced shaft and a cutting structure adapted to different shapes and thicknesses of rubber

• Uniform Φ5,5 mm granules — the constant size eliminates the need for additional sorting and ensures direct compatibility with modified asphalt and elastic flooring applications

• Simplified maintenance — the blades of the rubber granulator are individually removable for sharpening or replacement, without complete disassembly of the cutting chamber

• Versatility in feed — the rubber granulator accepts pieces from pre-shredded tyres, used conveyor belts, gaskets, hoses and other industrial rubber waste

Technical Specifications Rubber Granulator

Note: The exact dimensions and capacities may vary depending on the individual configuration of the rubber granulator equipment and the characteristics of the feed material.

Industrial Applications — Recycled Rubber Granules from Used Tyres

The main application of the rubber granulator is the recycling of used tyres (ELT — end-of-life tyres), a mandatory process under European legislation. The resulting granules have a diverse and continuously growing sales market, which turns the investment in this rubber granulator into a solution with a rapid return.

Companies already operating in waste management can add this rubber granulator as an additional source of revenue. The Φ5,5 mm granules are used directly in the production of modified asphalt (a technology that extends road service life by 30–50%), elastic flooring for playgrounds and sports halls, substrate for artificial turf and sound-insulation panels, in accordance with the requirements of Directive 2008/98/EC on waste .

A similar investment in industrial equipment has generated concrete results for UZINEX customers — for example, Airone doubled its production capacity after integrating equipment from UZINEX. In addition to tyres, the rubber granulator is also suitable for recycling waste from other industrial sources: conveyor belts, gaskets, hydraulic hoses and other technical rubber parts. Materials Processable with the Rubber Granulator

The rubber granulator equipment is designed to process a wide range of rubber-based waste, after the primary shredding and ferrous-metal removal stage. Flexibility in the types of accepted materials is a major advantage of this rubber granulator, allowing operators to diversify their supply sources and maintain a high level of utilisation throughout the year. Below are the main categories of compatible materials:

• Pre-shredded used tyres — car, truck, agricultural machine and construction machine tyres, after removal of the beads and reduction to pieces of 20–50 mm

• Industrial conveyor belts — belts made of natural or synthetic rubber, worn or damaged, cut into pieces compatible with the feed chamber

• Technical gaskets and membranes — parts made of EPDM, NBR or SBR rubber from the automotive, construction or hydraulic installation industries

• Hydraulic and pneumatic hoses — after removal of the metal inserts, they can be granulated to the standard size of Φ5,5 mm

• Other industrial rubber waste — protection mats, anti-vibration elements, bushings, pads and worn rubber dampers

Workflow — From Used Tyre to Marketable Granule

• Sorting and preparation: The tyres are sorted by size. The large-format ones pass through a twin-shaft primary shredder that reduces them to pieces of 50–100 mm. The metal rings are removed with a dedicated press.

• Secondary shredding and ferrous removal: The rubber pieces pass through a secondary shredder that reduces them to 20–30 mm. A magnetic separator extracts the steel wire, obtaining metal-free rubber at a rate of over 98%, ready to feed the rubber granulator.

• Granulation: The cleaned material enters the rubber granulator, where the X-shaped blade system reduces it to uniform Φ5,5 mm granules. At the same time, the textile fibres are mechanically separated with an efficiency of over 99%. The rubber granulator operates continuously, without stops for cleaning between batches.

• Sorting and classification: The granules produced by the rubber granulator pass through a vibratory screening system that separates them into dimensional fractions. Oversized particles are automatically recirculated for a second pass.

• Storage and delivery: The recycled rubber granules are stored in silos or packed in big-bag sacks, ready for direct sale to asphalt plants, flooring manufacturers or other end users.

Frequently Asked Questions about the Rubber Granulator

What processing capacity does the rubber granulator have?

This rubber granulator is available in four variants: LD600 (300 kg/h), LD800 (600 kg/h), LD1000 (800–1 000 kg/h) and LD1200 (1 000–1 200 kg/h). The effective capacity depends on the type and moisture of the feed material. The UZINEX team recommends the optimal model according to the estimated waste volume. What size are the granules produced by the rubber granulator?

The standard size of the granules produced by a rubber granulator is Φ5,5 mm, compatible with most commercial applications — modified asphalt, sports flooring, artificial turf substrate. For finer granulation, additional refining stages can be added downstream. Is the rubber granulator eligible for EU funding?

Yes. The rubber granulator and recycling equipment are eligible under several non-reimbursable funding programmes — NRRP, Just Transition, the Regional Programme and other lines dedicated to the circular economy. UZINEX provides all the necessary technical documentation (CE, ISO, DNSH) for the funding application. How long does the installation and commissioning of the rubber granulator take?

The mechanical installation and electrical connection of the rubber granulator take on average 2–3 working days, depending on the complexity of the line.
