Cone crushers have gained such wide acceptance that they may be regarded as standard in the intermediate-range size-reducing machines. A schematic diagram of a cone crusher is shown in Fig. 4.6 A.The drive is similar to that of a gyratory crusher. The inner cone or 'crushing head' is supported by the tapered concentric spindle, which is rotated by the …

The maximum feed size is approximately 8 0% of the feed opening. The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. The closed side setting can be calculated by deducting the stroke from the OSS.

Gyratory crushers can accept 8–10% moisture in operation, but the fine content should be preferably less than 10%. The crushing action in gyratory crushers is regarded as rings or 'helics' (spirals) of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher.

Gyratory crushers often are built into a cavity in the ground to aid in the loading process, as large haul trucks can access the hopper directly. JAW CRUSHER. Jaw crushers are also compression crushers that allow stone into an opening at the top of the crusher, between two jaws. One jaw is stationary while the other is moveable.

The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher.

Cone crushers take care of secondary and tertiary crushing applications. Fine and medium-sized aggregates (used in asphalt and concrete, for example) are created by an eccentrically rotating shaft that grinds the rocks between a robust metal cone and a fixed wall.
