No discussion of primary crusher selection would be complete without a comparison of the two leading types: the standard gyratory crusher and the Blake jaw crusher. Although their fields of application overlap to a considerable degree (at least in the realm of primary crushing) there is no real conflict between these two machines; one supplements the … Read more
A striking feature of the non-choking concave, is the character of the product. So far we have been dealing with crushers whose eccentric speeds are low enough to permit the material to fall, with each receding stroke of the active crushing member, the full distance allowed by the close CSS and open side OSS physical proportions of … Read more
On left is a showing of the “standard gyratory with straight concaves” is a section through any vertical, radial plane in the crushing chamber of one of the intermediate sizes of the crusher. In order to understand the crushing action in such a chamber it is helpful to consider the process as though each step took … Read more
Concaves on the right illustrate the cross section of a typical gyratory crusher, while the left illustrates the same crushing chamber, except that, in place of the straight-face concave, the non-choking type has been substituted. For the sake of direct comparison we have shown the same discharge setting in both diagrams, although a closer setting would be permissible … Read more
