### Calculate the Reduction Ratio and the Number of Milling

The limiting reduction ratio is the maximum feed size to the maximum product size (see formula below). R/R=F100/p100 This is the easiest method to estimate reduction ratio, especially when you dont have details about the machine. The F100 could be the
