[0002] The mining industry is one of the main application areas of jaw crushers. During the mining process, the original ore needs to be separated from the vein and crushed into suitable particle sizes for subsequent mineral processing, purification and processing. Efficient crushing equipment can improve the efficiency and output of ore crushing, reduce production costs, and meet the needs of mining companies for high-quality ore.

[0003] Existing technologies include: using optimized jaw plate design and stable frame structure to improve the stability and durability of the whole machine, improving the material crushing efficiency through reasonable jaw plate motion trajectory and optimized motion parameters, using convenient and fast jaw plate gap adjustment device to adapt to materials with different particle size requirements, and using highly wear-resistant jaw plate materials to extend the service life of the equipment.
