A jaw crusher is a type of heavy machinery used in the mining and construction industries to break down large rocks into smaller, more manageable pieces. It operates by using two jaws, one stationary and one movable, which crush the material as it is fed into the machine. This process is essential for preparing materials for further processing or for use in construction projects. Jaw crushers are known for their durability and efficiency. They can handle a variety of materials, including granite, limestone, and concrete. The size of the crushed material can be adjusted by changing the distance between the jaws, making them versatile for different applications.
