To produce 1 cubic meter (CUM) of M20 grade concrete, approximately 0.55 CFT (cubic feet) of coarse aggregates (20mm nominal size) and 0.28 CFT of fine aggregates (sand) are required. Modern crushing plants optimize this process through advanced equipment configurations.
A typical aggregate production line includes:
1. Primary Jaw Crusher (e.g., PE600×900, capacity 50-160t/h)
2. Secondary Cone Crusher (e.g., HPT300, max feed size 240mm)
3. Tertiary Impact Crusher/VSI Sand Maker (e.g., VSI1140, sand output 120-180t/h)
4. Vibrating Screens (3-4 deck, e.g., 3YK3070)
| Equipment | Model | Power(kW) | Capacity(t/h) |
|---|---|---|---|
| Jaw Crusher | PE750×1060 | 110 | 110-320 |
| Cone Crusher | HST250 | 250 | 150-380 |
| VSI Crusher | S8 | 315×2 | 200-280 |
| Screening | 4YK2460 | 30×2 |

Q: How to adjust aggregate gradation for M20 concrete?
A: Control crusher CSS settings and screen mesh sizes:
– Coarse aggregate: 20mm square mesh
– Fine aggregate: 4.75mm mesh
Q: What’s the typical production cost per ton?
A: $3.5-6/ton depending on raw material hardness and plant configuration.
