The factorial design is accomplished using MCS data. Factorial design is used to determine failure rates using shape parameter, scale parameter and time failed data. Failure rates of jaw crusher and its components are examined by 2 3 full factorial designs with two levels (high level and low level) and three variables. High level is …

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.

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other makes an eccentric movement. There are also primary …
