· A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer’s data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.

· A cone crusher punishes itself in every minute of operation. It squeezes a dense mass between heavy castings until the mass disintegrates. It abrades and minces aggregate until the material yields to the applied forces. It rumbles and vibrates and bangs as its core shaft spins eccentrically to capture and reduce chunks of aggregate.

· This follows directly from the enhancement of the flow rate through the crusher as a result of larger gap sizes between cone and mantle. This results in increased throughput but provides less opportunity to break particles and so leads to the coarser product observed.

· Primary gyratory crushers are designated by two numbers. These are the size of the feed opening (in inches) and the diameter of the mantle at its base (in inches). A 60″~x~89″ crusher would have an opening dimension of 60 inches (152 cm) and a diameter across the base of the mantle of 89 inches (226 cm).

· A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29”x49”, the crusher gape would be 32” and the width would be 54”.
