Jaw crusher is commonly used in mining machinery production line, equipment, one of the highest compressive strength was broken material does not exceed 320 mpa, more commonly used in the head.Application of the main places of mine production lines, metallurgy manufacture development production line, building material production line, the highway construction and other industries.
Because of the jaw crusher is widely used, it is particularly important to the use of the method of jaw crusher, how to use the jaw crusher is the correct method of use, to ensure the normal operation of jaw crusher, to achieve optimal efficiency, the highest.The following these aspects, must abide by it.
