The result size of crushing down to 50 mm, while grinding size range from hundreds to tens microns or < 10 microns. Reduction ratio. Crushing is performed in several stages, reduction ratios are ranging from three to six in each stage. The reduction ratio in grinding can up to 100, therefore it consumes a considerable amount of energy.

Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 ratio. The finer the crushing, the smaller the reduction ratio. These production improvements come from a number of engineering changes, but a large part is due to better crushing chamber design.

If a single-stage reduction is required, then depending on the feed-to-product-size ratio of reduction, either a Single or Double Roll Crusher can be selected. Regardless of the crusher type selected, Roll Crushers allow for the material to fracture along naturally occurring cleavage lines, which helps with minimizing fines generation.

Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
