A jaw crusher is a type of machine used to break down large rocks for use in construction, mining, and other applications. It consists of two plates or jaws, one of which is stationary and the other is movable. The movable jaw compresses the material against the stationary jaw, crushing it into smaller pieces.
Jaw crushers are versatile and can be used to crush a variety of materials. They are typically used for breaking down hard and abrasive stones such as granite, basalt, and quartz. However, they can also handle softer materials, including limestone, sandstone, and gypsum, depending on the specific design and capabilities of the jaw crusher in use.
