The Raymond Mill Model 3R1510, manufactured by SBM, is a key grinding equipment widely used in sand and aggregate production lines. Designed for processing non-metallic minerals like limestone, calcite, and dolomite, it delivers fine powders (80–325 mesh) for high-quality concrete and asphalt mixtures.
– Grinding Rollers: 3 rollers, 150mm diameter × 100mm height
– Max Feed Size: ≤15mm
– Output: 0.5–3.5 t/h (varies by material hardness)
– Motor Power: 15 kW
– Fineness Adjustability: 80–325 mesh

The 3R1510 is typically paired with jaw crushers (primary crushing), vibrating screens (grading), and bucket elevators (material transport). For example, a 50tph limestone-to-sand line might include:
1. Jaw Crusher → 2. Raymond Mill 3R1510 → 3. Vibrating Screen → 4. Finished Silo.
Q: How to maintain the grinding rollers?
A: Lubricate bearings every 100 hours; replace worn rollers after ~800 hours.
Q: Can it process quartz?
A: Yes, but output drops by ~20% due to higher hardness (Mohs 7).
A Vietnamese contractor deployed two 3R1510 units to produce 200-mesh limestone powder for local road construction. The line achieved 6t/day output with ≤5% moisture content, reducing drying costs by
