Gyratory Crusher

The schematic is given in Fig.(2). The gyratory crusher consists of a truncated conical casing, inside which a crushing head rotates eccentrically. The crushing head is shaped as an inverted cone and the material being crushed is trapped between the outer fixed, and the inner gyrating, cones, and it is again forced into a narrower and narrower space during which time it is crushed. As the crusher is continuous in action, the fluctuations in the stresses are smaller than in jaw crushers and the power consumption is lower.


In jaw crusher, and gyratory crusher the principal size reduction mechanism is the compressive action of two pieces of steel against the material.
