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 they close together. This process is essential for preparing materials for further processing or for use in construction projects. These machines are known for their durability and efficiency, making them a popular choice for various applications. Jaw crushers can handle a wide range of materials, including granite, limestone, and concrete, and are often used in quarries and recycling operations to produce aggregates.
