Embodiment
[0021] In this embodiment, we take the sieve analysis method as an example to describe the specific implementation process of the present invention in detail, as figure 2 As shown, the specific steps are as follows:
[0022] 1. Select a representative sample. Here we take a sample from a certain place as an example. The main components are quartz, feldspar, felsic debris, a small amount of opaque minerals, and a small amount of mica. The roundness of the particles is mostly sub-prismatic.
[0023] 2. The standard sieve is 2000-63um, the particle size interval is 0.25Φ, and the sieve analyzer is the sonic automatic sieve analyzer manufactured by the Nanjing Institute of Geography and Lake Sedimentation, Chinese Academy of Sciences. A representative sample of about 200g is selected using the sieve analyzer In the range of 710 ~ 63um, sieve according to the particle size interval of 0.25Φ. The vibrating sieve generally takes about 10 minutes. The quality of each particle size is...
