how many cft of aggregate for 1cum for m20

Crushing and Sand Making Production Line for M20 Concrete Aggregates

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.

Core Equipment Configuration

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)
