This type of crusher is designed for the first stage of crushing. Jaw crushers are employed as primary crushers in mines and composed of a fixed jaw and a moving jaw.
The jaw size is specified by the dimensions of the upper rectangular inlet of the crusher. Rocks are crushed by the pressing and impact forces exerted by the jaw.
High strength and high crushing capacity of rocks, a high-strength structure, reliable performance, and rapid and easy replacement of spare parts are among the main features of jaw crushers.
Lower erosion and higher strength than similar crushers are considered the key advantages of jaw crushers. While increasing the efficiency, the lubrication system reduces the maintenance costs of jaw crushers.
