According to the different thickness of the material, there are several kinds of grit sizes analysis methods:
Sieve analysis, which uses a set of sieves with different apertures for grit size classification. Its advantages are simple equipment and easy operation, but the disadvantage is that it is greatly affected by the shape of the grits;
Water conservancy Settlement analysis, which uses the different sedimentation speeds of different sizes of grits in the water and is divided into several levels. It is different from the sieve analysis method. The equivalent spherical diameter of speed;
Microscope analysis is mainly used to analyze fine-grained materials. It can directly measure the size and current situation of the grits.
