This is sufficiently warm to allow the bearing to slide over the shaft while not hot enough to damage any components. In any case, do not heat open bearings above 250 F. For bearings that have closures and are greased for life, 210 F is recommended as a maximum temperature so the 150 F difference over shaft temperature may have to be …

The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501). The crushing head is carried on a short solid main shaft (515) suspended …

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.
