India’s growing infrastructure demands high-quality aggregates, and centerless grinding machines play a critical role in refining abrasive materials like quartz, granite, and basalt for construction. These machines excel in producing consistent particle sizes, essential for concrete and asphalt mixes.
Modern centerless grinders used in aggregate processing offer:
– Grinding Wheel Diameter: 300–600 mm
– Regulating Wheel Speed: 10–200 RPM (adjustable)
– Material Removal Rate: Up to 0.5 mm/pass
– Tolerance: ±0.02 mm
| Model | Power (kW) | Max. Feed Size (mm) | Output Capacity (T/H) |
|---|---|---|---|
| CG-300 | 15 | 30 | 5–8 |
| CG-500 | 22 | 50 | 10–15 |

Centerless grinders are often paired with jaw crushers and vibrating screens in a closed-loop system. For example, crushed basalt is fed into the grinder to produce 0.1–3 mm sand for high-strength concrete.
Q: How to reduce wear on grinding wheels?
A: Use water-cooling systems and select alumina-based wheels for hard aggregates.
Q: Can it process recycled concrete?
A: Yes, but pre-screening (<10 mm) is recommended to avoid wheel damage.

A client upgraded their line with a CG-500 centerless grinder, achieving 14 T/H output of M-sand (IS 383 Grade). Downtime reduced by 30% due to automated wheel dressing.
