Influence of Sieve Surface Attitude on Sieving Performance of Granular Materials with Non-Uniform Feeding Conditions

Round 1

Reviewer 1 Report

The article was well written. The screen surface particle distribution is an important factor affecting the screening performance.  The result of the study canimprove the screening performance of non-uniform feeding, and provide reference for the material screening of non-uniform feeding.

Reviewer 3 Report

The research method of this paper has certain novelty, and the specific comments are as follows:

1. In the research, the research on screening efficiency mainly focuses on the equipment structure and working parameters, but less on screening objects. Spherical and non-spherical particles show completely different self-locking when contacting each other. It is too simple to equate rice grains with spherical particles, which is not conducive to research and analysis.

2. Some symbols in formula (1) and (2) are not explained and the unit is not.

3. Is yi in formula (3) the same letter as y1, y2, y3, etc. in the text? If so, how can the number of particles be multiplied by the coordinates?

4. In the study, the non-spherical particles were converted into spherical particles, referring to the relevant literature. However, whether to simplify to spherical particles should be determined according to the structural characteristics of the research object.

5. What is the source of parameters in Table 1?
