Background

The earth-rock dam has been widely used due to its simple structure and local material. The earth and rockfill dam material has grading requirements on filling materials of all functional areas so as to ensure that the dam body has stable structure and better seepage-proofing effect. During the filling process of the filling material, the particle composition analysis of the filling material is needed. The particle size distribution is also called particle size distribution. The number of each level of granularity in the bulk material composed of different granularities. Often expressed as a percentage of the total amount. Continuous gradation composed of uninterrupted particle sizes of various levels; a discontinuous gradation consisting of only a certain number of levels of granularity. Reasonable particle size distribution is an important way to achieve low porosity in the furnish.

The screening of the particles is generally carried out by dividing the solid material into the desired particle size by sieves having different mesh sizes. Often, the combination with crushing makes the particle size of the crushed material nearly equal to ensure that certain requirements are met or excessive crushing is avoided. The screening machine is a common screening device, and utilizes the relative motion of bulk materials and a screen surface to make partial particles penetrate through a screen hole, so as to divide materials such as sand, gravel, broken stone and the like into vibrating screening mechanical equipment with different grades according to the particle size. The particle grade of the screening depends on the screen surface, which is divided into grate, plate screen and mesh screen.

The conventional particle grading analysis is that after a person collects materials in a selected sampling area, the person manually screens the materials by hand-operated sieves with different apertures to separate filling materials with different particle sizes in various intervals, the weight of the filling materials in each particle size interval is obtained by weighing, and then the proportion of the particle grading is obtained by calculation. The traditional test for obtaining the grading data of the geotechnical particles is mainly completed manually, the labor intensity of the manual work is high, the on-site sampling time is long, the work efficiency is low, and the connection of subsequent filling operation can be influenced.
