Rock Crushing Rule of Thumb

If the hourly tonnage to be crushed divided by the square of the required gape in inches is less than 0.115, use a jaw crusher; otherwise use a gyratory. (If the required capacity in metric TPH is less than 162 times the square of the gape in metres, use a jaw crusher.) Source: Arthur Taggart. Crushing in Mineral Processing
