No crusher is fully perfect in the world. Even though impact crusher is so popular, it still has more or less problems if being used for a much longer period. Then, the following content will discuss about these problems. During the working process of impact crusher, rotors are in the state of high-speed revolution. Most rotors used nowadays are molded by casting. Due to the careless casting, some part of rotors are irregular and not in balance.

During the working process of impact crushing machine, revolving speed of rotors can reach to 760r/min. Due to the high revolving speed of rotors, bearings will be overheated or even burned out. Oil holes are in the sides of hammer plates. Bearings are quite far from the inner wall of oil holes. Even though you inject the holes with many lubricating oil, bearings of impact crusher can still not get lubricated. There is no doubt that the bearings would be seriously worn out during the working process of impact crusher.

To solve the overheating of bearings, there are two ways. At first, aiming for the imbalance of rotors, you should pay much attention to the quality and casting work of rotors during the purchasing process. Then, aiming for the lubricating failure of bearings, you can do as followings like frequently checking the lubricating situation, changing the lubricating oil and cleaning the bearings. 

If the overheating of bearings can still not be solved after taking the above ways, you should blame it to the working failure of bearings. You should change them with new ones. As a professional supplier of stone impact crusher, FTM Crusher Company has offered the discounts for you on website!
