1/1/2016· 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. Manufacturers data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.
A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening.
