Crumb rubber mesh-band output from an ambient grinding line
Yield share, particle size range, primary application, and indicative price for the four mesh bands — coarse, mid-coarse, fine, and ultra-fine — that an ambient grinding line produces from waste tyres.
| Mesh band | Particle size | Yield share (default operation) | Primary application | Indicative price (₹/kg) |
|---|---|---|---|---|
| Coarse 4-10 mesh | 2.0-4.7 mm | 25-35% | Playground surfacing, rubber mulch, lightweight backfill | ₹15-22 |
| Mid-coarse 10-30 mesh | 0.6-2.0 mm | 30-40% | Artificial-turf infill, rubberised concrete, moulded products | ₹18-26 |
| Fine 30-80 mesh | 0.18-0.6 mm | 15-25% | CRMB binder, high-grade moulded products, gym flooring | ₹22-30 |
| Ultra-fine 80-100+ mesh | Below 0.18 mm | 5-10% | Sealants, adhesives, compound filler | ₹28-35 |

How to read this table
- Yield shares are from a default ambient line operation — screen and classifier settings can shift the distribution toward finer bands at the cost of throughput and energy
- Particle size ranges are nominal; actual output depends on screen aperture settings and feedstock tyre type
- Indicative prices are per kilogram for material meeting ASTM D5603 quality limits — refer to the Crumb Rubber Specification Sheet for the exact limits per band
About this table
An ambient grinding line processes waste tyres at room temperature, using a sequence of shredders, granulators, and classifying screens to reduce the rubber to progressively finer particles. The output is not a single uniform product — it is a blend of four mesh bands, each with a different particle size, a different primary application, and a different price. Understanding this mix is essential for any crumb rubber business because the revenue per tonne of tyre processed depends on the proportion of each band in the output and the prices each band fetches in the market.
The coarse band (4 to 10 mesh, 2.0 to 4.7 mm particles) is the simplest to produce and typically accounts for 25 to 35 percent of output. It goes into playground surfacing, rubber mulch, and lightweight fill applications where particle size is not critical. The mid-coarse band (10 to 30 mesh, 0.6 to 2.0 mm) is the largest single fraction at 30 to 40 percent of output and serves artificial-turf infill, rubberised concrete, and general moulded products — it is the primary volume driver for most Indian crumb rubber plants. The fine band (30 to 80 mesh, 0.18 to 0.6 mm) represents 15 to 25 percent of output and is required for CRMB binder production and higher-grade moulded products; this fraction commands a noticeable price premium over coarse material.
The ultra-fine band (80 to 100 mesh and above, below 0.18 mm) accounts for only 5 to 10 percent of ambient line output, limiting volume, but attracts the highest price because sealants and compound fillers require this particle size. The yield distribution can be shifted by adjusting the number of grinding passes, screen aperture, and classifier settings, but this comes at the cost of higher energy consumption and lower throughput per tonne. If your buyer mix requires more fine or ultra-fine output than a default ambient line delivers, a supplementary cryogenic grinding stage is the practical route to increasing that fraction. Use this table alongside the Crumb Rubber Specification Sheet to build batch certificate of analysis targets for each mesh band.
Key insights
- The mid-coarse 10 to 30 mesh band is the largest single fraction (30 to 40 percent of output) and the primary volume driver for most Indian crumb rubber plants
- Ultra-fine material (80 to 100 mesh and above) makes up only 5 to 10 percent of ambient line output, limiting revenue contribution despite the higher per-kilogram price
- Fine 30 to 80 mesh commands a meaningful price premium over coarse material and is the band required for CRMB binder production
- Increasing the fine or ultra-fine fraction beyond default levels requires additional grinding passes or a cryogenic stage — both reduce throughput per hour
- Total revenue per tonne of tyre processed is the weighted average of the four band prices multiplied by their respective yield shares
Methodology & sources
Yield share ranges and particle size bands reflect typical ambient granulator performance for mixed passenger and light commercial vehicle tyres. Actual output distribution varies with tyre composition, moisture content, wear on grinding elements, and screen aperture settings. Indicative prices are based on Indian market data as of 2024–25 and represent delivered landed prices for material meeting ASTM D5603 quality limits.
