These curves represent gyratorys in 54"x74"; 60"x89" size class. A gyratory crusher mantle surface speed is rated up to 30 m/s for the larger size ranges and at the mantle's 2261 mm (89") larger diameter and 275 rpm. Therefore, it can be argued that CAHM could also be able to achieve this higher surface speeds.
