Crushing (grinding) ratio is the crushing (grinding)machines ore maximum block size (D) and the stage crushing (grinding) machines offering the largest nugget size (d) ratio, that is broken (mill) crushing ratio i = D / d. Its size, indicating that the ore after break (ground) after broken multiple narrow particle size, particle size is a measure of the degree of change before and after the ore crushing and balanced distribution of crushing parameters (grinding) machines work. Nugget maximum particle size is generally 95% of the material through the mesh size of the square is represented.
Total breaking work (grinding) ratio is equal to paragraphs break broken (grinding) broken ratio of the product. For example, a three-stage crushing, crushing ratio of each segment, respectively i1, i2, i3, said the overall total reduction ratio i = i1 × i2 × i3.
