Gyratory Crusher
Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.The spindle is suspended from a "spider" and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within the fixed crushing …
Roll Crusher
The maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. The friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls.
