Blake crusher designed with a vertical stationary jaw

The original Blake crusher was designed with a vertical stationary jaw. Probably the first departure from this arrangement \Vas an 84- x 66-in. crusher, built in 1914. This machine incorporated a reversal of the conventional design, in that the swing jaw was made vertical. Later, when the Superior line was developed, a

compromise between these two extremes was used in several of the sizes; that is, both jaws were sloped.

Each of these three arrangements has certain features which are advantageous, and others which are unfavorable. Present indications are that the original arrangement, with vertical stationary jaw, will continue to hold a leading position.

Crushing angles in standard Blake-type machines generally run in the neighborhood of 27 deg. at the minimum open-side discharge setting. The ratio-of-reduction at minimum recommended settings and with straight jaw plates average about 8:1, in the range of sizes from 15- x 10 in., to 60- x 48-in., inclusive.
