"Computer Aided Design of Jaw crusher"
Blake type jaw crusher, primary crushers in the mineral industry; attains maximum amplitude at the bottom of the crushing jaws as the swinging jaw is hinged at the top of the frame. These crushers are operated by and controlled by a pitman and a toggle. The feed opening is called gape and opening at the discharge end termed as the set.

Crusher Discharge Product Size & Shape
The clean-breaking crusher is the economical crusher, both from the standpoint of power consumption, and general wear and tear.1 And, because the non-choking concaves make for cleaner breaking, they benefit the crusher in both of these respects. At comparable discharge settings the power saving may run as high as 20%.
