Jaw crusher, as coarse crushing equipment, has larger discharge fineness, usually below 300-350mm (depending on the model). Impact crusher, as medium or fine crushing equipment, naturally has smaller discharge fineness. Here, we should notice that due to different material properties, the discharge fineness will also be different.
