Dynamic Characteristics of Crusher Supporting Structures

during the process of its crushing coal. The record shows random oscillatory motion typical of a situation in which the eccentricity of a rotating shaft keeps chang­ ing. This is expected in a crusher as the centre of gravity of the coal mass changes arbitrarily within crusher chamber.


In this way, an adjustment of the eccentricity e of the crusher 1 is made possible without relatively large adjustment devices. FIG. 2 shows a design variant of the crusher 1, and two eccentric bushings 12 are provided, which are seated on the bearing journals 20 of the eccentric shaft 16. Here, by way of the bearing elements 17, the eccentric

The crushing process takes place between a ixed and a moving jaw. The moving jaw dies CONE AND GYRATORY are mounted on a pitman that has a recipro- CRUSHERS cating motion. The jaw dies must be replaced regularly due to wear. Both cone and gyratory crushers have an oscil-


exact breaking load can be calculated. When the bolts are over­ stressed and break, the toggle remains in the crusher and simply hinges about the central shaft. This action puts the crusher in neutral and crushing ceases. New bolts are inserted and the crusher is back in operation with minimal downtime. Problems Associated with Jaw Crushers
