Mathematically, the reduction ratio is calculated by dividing the size of the feed material by the size of the product. For example, if the feed material has a size of 100 millimeters (mm) and the product size after crushing is 20 mm, the reduction ratio would be 5:1 (100/20 = 5). This means that the crusher has reduced the size of the material ...
