A jaw crushing machine is a type of equipment used to break down hard materials, such as rocks, minerals, and ores. It consists of a fixed jaw plate and a movable jaw plate that is positioned in a V-shaped configuration. As the movable jaw plate moves back and forth, it crushes the material against the fixed jaw plate.
