The grading is the distribution condition of all levels of particle size particles of the aggregate, and can be determined through a screening test. Classification: 1. continuous grading: the continuous grading is that after a certain mineral aggregate is screened in a standard screen, the particles of the mineral aggregate are continuously distributed from large to small, and each stage occupies a proper proportion. The mineral mixture which is formed by matching the particle sizes from large to small and is called continuous grading mixture. 2. Gap grading: in the whole interval of mineral aggregate particle distribution, one or several continuous particle fractions are removed from the middle to form a discontinuous grading, so-called gap grading; 3. continuous and continuousOpen grading: the overall mineral aggregate particle distribution is narrow, with the largest to smallest particle sizes occurring only over a few fractions in a continuous fashion, forming a so-called continuous open grading.
