Influence of jaw crusher parameters on the quality of

A parameter study using a jaw crusher is designed to investigate the influence of feed gradation, feed rate, crusher setting and crusher speed on the crusher After measuring the crusher’s OSS, the CSS should be calculated to define what the opening of the crusher is to be and enable adjustment to the desired setting. The way we measure the opening varies according to the profile of the jaw: top-top, top-bottom or bottom-top. The tables for the cavity should be checked to figure out which wayMeasuring the crusher setting 911 Metallurgist
