The size of a jaw crusher is measured by the top opening of the crushing chamber. For example, a 48" x 42" jaw crusher measures 48" from one crushing jaw to another and is 42" across the width of the two crushers. The primary applications for using jaw crushers are: Crushing different kinds of ore; Reducing building rubble to pieces

With the specific compressing force of 5.5 N/mm 2, the fine fraction of −0.15 mm was 11.85% higher than that of jaw crusher, whereas the −0.074 mm fraction was increased by 8.68%. The d50 value of HPGR products was the smallest. By calculations with Eq. (1), particles from conventional jaw crusher had a. Conclusion
DEM simulations were validated on the basis of experiments in a laboratory jaw crusher in the size reduction of a gold ore. Additionally, a sensitive analysis of the simulation model was carried out to investigate the effects of the closed side setting (CSS) and frequency on capacity, power, compressive force and reduction ratio.

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.
1.) Obtaining the size or surface area required for the use of the ore or material. 2.) Allowing ease of transportation and storage. 3.) Separating the different minerals contained within the ore and to release them from one another. 4.) Obtaining the size or surface area required for the enrichment stage.
