How To Choose Crushing Equipment

In the daily production and processing process, the general impact crusher is equipped with a jaw crusher to complete the production and processing operations, mainly because when the material is large, the jaw crusher is required to perform the first break, and then enter the impact crusher. Secondary crushing processing, of course, if the material itself is small, it can be directly processed into the impact crusher, and the specific matching depends on the production material.
