author:dahua1 time:2019-07-05

Followings are the standards of sand granularity of sand making machine:

1. Ultra-fine sand: fineness modulus 1.5-0.7, average particle size is below 25mm.

2. Fine sand: fineness modulus 2.2-1.6, average particle size is 0.35-0.25mm

3. Median sand: fineness modulus 3.0-2.3, average particle size is 5-0.35mm

4. Coarse sand: fineness modulus 3.7-3.1, average particle size exceeds 5mm.
