Uniform particle size distribution: The crushing chamber of a gyratory cone crusher is designed in such a way that the particles are subjected to a uniform force throughout the crushing process. This ensures a more uniform particle size distribution in the final product. Lower operating costs: Gyratory cone crushers have a lower operating …

Abstract. Cone crushers are used in the aggregates and mining industries to crush rock material. A model to predict the worn geometry of cone crushers was previously developed. In that model there was some disagreements between predicted and measured geometry and several effects were suggested to explain the discrepancy in the …

The cone crusher also has a gyratory motion, but has a much flatter mantle or cone than does the gyratory crusher. The top bowl is spring-mounted. It is used as a primary or secondary crusher. Secondary crushers include the single-roll crusher and the double-roll crusher which have teeth on the roll surface and are used mainly for coal.

The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 8.2). Power is transmitted from the source to the countershaft to a V-belt or direct drive.

GYRATORY CRUSHER. A gyratory crusher uses a mantle that gyrates, or rotates, within a concave bowl. As the mantle makes contact with the bowl during gyration, it creates compressive force, which fractures the rock. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.

Crusher performance is significantly impacted by liner material wear, wear profile, feed size distribution, feed type, and feed rate (Bearman and Briggs, 1998). This work is based on cone crushers, but the similarities between these types of crushers and gyratory crushers suggest that the results may be transferable to gyratory crushers.
