The benefits of choosing a cone crusher for hard rock

　　Hard rock, as the name suggests, is rock with a relatively hard texture, such as granite, basalt, etc. For the crushing of this kind of hard rock, three types of jaw crushers, impact crushers and cone crushers can be used. The machine is more suitable for hard rock crushing operations. The specific knowledge about hard rock crushing is introduced as follows:

　　1. Reasons for choosing cone crusher for hard rock crushing

　　(1). Due to the high hardness of hard rock, it will cause a lot of wear and tear on the equipment when crushed. The impact crusher adopts the principle of impact crushing, and uses a high-speed moving blow bar to hit the material for crushing. The blow bar bears the brunt, and the frequency of replacement will be accelerated. , which will delay more production time. The choice of cone crusher is different. It adopts the principle of laminated crushing, uses the eccentric movement of the crushing wall to crush the material, and *ly reduces wear and tear. Type crushers are more suitable for hard rock crushing;

　　(2). Although the particle shape of the finished hard rock processed by the cone crusher may not be as good as that of the impact crusher, it has less needle-like materials and the particle size of the finished product is relatively uniform. High efficiency, so for enterprise users under general production requirements, it is better to choose a cone crusher;

　　(3). In terms of safety, the cone crusher adopts a spring hydraulic safety device, which can automatically increase the ore discharge port when there are foreign objects that cannot be broken in the crushing cavity or the equipment is overloaded, so that the foreign objects can be discharged to ensure its safety *. Common crushers do not have the function, so compared with other equipment, cone crusher is more suitable for hard rock crushing operations.

　　2. How does the cone crusher realize the hard rock crushing operation

　　When the cone crusher is working, the rotation of the motor passes through the pulley or coupling, the transmission shaft and the cone part are forced by the eccentric sleeve to make a swinging motion around a fixed part, forcing the crushing wall to sometimes approach and sometimes deviate from the fixed sleeve. The surface of the rolling white wall on the *, so that the ore will be continuously impacted, squeezed and bent in the crushing chamber to realize the crushing of the ore.
