· Here is what a well choke fed jaw crusher looks like! Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the jaw’s cavity full to maximize rock-on-rock compression and crushing. Notice the shape of the liner profiles? A crusher is choke fed when the chamber is full […]

13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.

· Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform. Cone crushers do an excellent job of providing finished material that's relatively homogenous.

· Most operations use a combination of hoppers, feeders and surge bins to achieve optimum feeding processes within the cone crushing circuit. Never run the cone empty or with sudden erratic surges. This causes the head to spin from one direction to the other at a range from 200 to 300 rpm – an inertia and momentum that leads to potential

The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. 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 6.8 ).
