Quality is based on each client’s specific needs. The hardness of the finished, crushed product, depends on the hardness of the material being fed into the crusher. The gradation will be dramatically affected by the type of crusher used. The jaw crusher will generate less dust, less powder and less fines. The jaw is a compaction crusher and squeezes material while crushing. The impact crusher is an explosion crusher that impacts and explodes material. The quality of the finished product does depend on one’s perspective of exactly what the target is. If one’s target is to produce fines, the impact crusher may be a better choice. If the target is a coarser blend of material, the jaw crusher may be best. This is a broad view of jaws vs. impacts and will vary based on numerous factors.
