Reasons for choosing a cone crusher for hard rock

Hard rock is a rock with a harder texture, such as granite, basalt, etc. Jaw crusher, impact crusher and cone crusher are often used for the crushing of this type of hard rock. However, from the comparison and analysis of crushing efficiency, finished particle shape and wear rate, cone crusher It is more suitable for the crushing of hard rock. The introduction of knowledge about hard rock crushing is as follows:
 

1. Due to the high hardness of hard rock, it will cause wear and tear to the equipment during crushing. The impact crusher adopts the principle of impact crushing, using the high-speed moving blow hammer to hit the material to break, and the frequency of the blow hammer replacement will be accelerated, so that the More production time will be delayed. The choice of cone crusher is different. It adopts the principle of lamination and crushing, which uses the eccentric movement of the crushing wall to crush the material and ly reduces the wear. Therefore, considering the wear rate alone, the cone crusher is better than the counterattack. The crusher is more suitable for hard rock crushing.

2. Although the granular shape of the finished hard rock processed by the cone crusher is not as good as that of the impact crusher, it has less needle-like material, and the particle size of the finished product is relatively uniform. The crushing efficiency of the cone crusher is high, so for general For enterprise users with production requirements, it is quite good to choose cone crusher.

3. The cone crusher adopts spring hydraulic safety device, which can automatically discharge the ore port when the crushing chamber has unbreakable foreign objects or the equipment is overloaded, so that the foreign objects can be discharged to ensure its .
