The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.

In the aggregate sector, single toggle jaw crushers (Figure 2) are often preferred. Within the scope of the study, an innovation on the single toggle jaw crusher was developed. The main drawbacks of jaw crushers are their low crushing capacity and extended CSS duration. Unlike current jaw crushers, the amount of eccentricity and pitman angle were
