  • What is a Jaw Crusher? MEKA Crushing Equipment

    / PARTS AND MAIN PARAMETERS OF JAW CRUSHERS Jaw crushers are generally defined by their opening size. For example, a 900x650 mm crusher refers to a crusher with an inlet measuring 900 mm by 650 mm. The main parts and main technical parameters of a jaw crusher are presented below.


    d1 and d2 are parameters that are characteristic of the crusher. They are determined primarily by the setting of the crusher. Data from operating crusher machines indicate that both d1 and d2 are proportional to the closed side setting. d1 is the smallest size particle that can be retained in the crushing zone during the opening phase of the cycle.
