Crusher architecture
Jaw crushers use a reciprocating jaw; gyratory crushers use a gyrating mantle. Compare openings, feed, discharge and maintenance against the same operating duty
Mill and drive
Girth-gear/pinion drives transmit torque through gear mesh and differ from gearless drives. Selection combines duty, layout, electrical supply, maintenance and engineering constraints
Avoid combining unrelated ratings
Maximum ratings from different models cannot be combined into a fictional configuration. Throughput, power and product size need a consistent technical basis
