Factors to Consider When Selecting the Proper Roll
When taking this into account, you must also refer back to the feed size to see if the ratio of reduction requires multiple stages of crushing. A good rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction.
