European impact crusher strengthens crushing size uniform
During the crusher machine’s operating, in order to use little energy to achieve to the best crushing effect, the materials’ crush should follow their natural crack, joint plane and layer inside, etc. equimolecular bond and produce at the weaker point. The crushing machine generally applies the methods such as extrusion, cut or grind to crush. But use the high speed crushing energy and make the materials crush along their weak face at free state can have more satisfactory effect. Because the energy use ratio of European impact crusher is high, materials’ crushing size are uniform and the crush vibration is smaller, so they apply widely on the coal dressing, metal mine’s beneficiation and the manufacure of cement. Generally the European impact crusher can classified into single roll, double roll and multi roll. The adjust mode of ore discharge mouth and stone crusher’s safe system are the two important parts to evaluate the performance of roll crusher. The general impact crusher applys the mechanical methods to adjust the ore discharge mouth, the spring is the safe system and it is very reliable, it also strengthens the crushing process at the same time and to reach the product size uniformly.
