Reduction ratios in crushing

A reduction ratio is the size a crusher will break down feed material into. In other words, the reduction ratio of a crusher tells you how big a piece of material you can feed into the crusher for it to break it up into the desired sizes. The reduction ratio for crushing gives us important information about how large or coarse the feed ca…See more on machinerypartner
