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 roller crusher is a familiar machine for the crushing processing of ore. It has a large crushing ratio and can be used for the crushing of many different ores. It is the crushing operation of ore. Indispensable for the critical crushing equipment, the main shaft acts as a power transmission and support roller on the roller crusher.
Coupling Rotation Without Crusher Movement. If the coupling rotates but the crusher doesn't, the issue may be with the transmission coupling, a broken gear key, or spindle breakage. Disassemble the machine to locate and replace the faulty parts. Strong Knocking in the Drive Shaft
