Lifespan of stone crusher is enhanced greatly due to internal spring mechanism. Internal pressure resistance ability can effectively extend the service life of stone crusher. Stone crusher adopts the device USES dry oil and two sealing methods to prevent dust impurities from entering the device body. It protects effectively the body internal cleanliness and prolongs the service life of bearing, the spring mechanism.

As an advanced machine, cone crusher plays a vital role in the process of building construction; its expense is undoubtedly relatively high. So good maintenance is entailed. Among the amount of maintaining process, keep the hydraulic pressure system and hydraulic pressure oil clean is one of the most important part. To make sure have a good performance of this part, one should realize the following aspects:

With the following structure features of the impact crusher, it can applied widely: 1, evenly broken with multi-cavity , suitable for hard rock crushing ; 　　 2, low inlet for easy production line layout and increased feeding size; 　　 3, the new wear-resistant materials enables a long lifespan of flat hammer, counterattack and liners ; 　　 4, chromium plate hammer and a unique, high impact liner, are especially suitable for hard rock crushing, it is high efficiency and energy saving; 　　 5, evenly board structure enables discharging materials small and cube-shaped, without inner sheath,what is more, the size can be adjusted; 　　 6, simplified broken process; 　

Besides, the operator should check the new tire that is easier to be loose regularly. In daily working, pay attention to every element of stone crusher. When you find abrasion condition, examine the degree of abrasion in time and replace it. The lubricating oil must be clean and keep sealed well, because oil has a direct effect on lifespan of bearing and running rate of stone crusher.
