Cone Crushers: Types, Benefits, and Applications
An existing operating plant was making rod-mill feed nominally —5/8 in. with a total plant feed rate from the primary crusher product averaging 1,000 tph of —6 in. top size. Samples of this feed over several weeks of operation showed an average of 40% —5/8 in., which means that 600 tph of material must be crushed in two stages of crushing.

Reduction ratios in crushing | Machinery Partner
The limiting reduction ratio is the maximum feed size (known as F100) that can be put into the crusher and the maximum product size (p100) the crusher can produce. This ratio is a good starting point when choosing a crusher, as it will give you an idea if the crusher will be able to handle the size of rocks you want to work with.
