Repair the Shaft of Broken Crusher

Cone crusher is the commonly used crushing equipment. During its production process portable diesel concrete mixer, the broken of shaft is a kind of common fault. The frequent broken of shaft will not only affect the normal production of cone crushing machine, but also increase its daily maintenance and repairing work. Henan Daswell Machinery will analyze the causes and solutions of this failure in the following paragraphs:

Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixer,Concrete Pan Mixer,egg laying block machine,etc. We will provide you with the best product and service.

After the analysis, we draw a conclusion that there are three general reasons for the fracture of main spindle during the process of cone crushing machine in the long run: its quality, external factors and the fatigue of fracture. For the first two reasons, choose suitable materials according to the actual situation of the spindle to ensure the normal influence of external factors, which can avoid the fracture problem. But for third one, its reason is to feed on one side, which leads to the uneven distribution of materials in the crushing cavity. The imbalance of the load at the bottom of crushing cavity results in impact load of the spindle. Therefore, the spindle is periodically affected by the impact force during its eccentric rotation, so that the spindle will receive continuous bending, which is the reason for the fatigue fracture of the spindle. In addition, cone crusher can be modified to solve the problem of the broken spindle.

The baffle plate in the feeding hopper should be adjusted for the free fall height of materials, and then adjust the upper crossbeam to be parallel with the feeding direction. Maintain the packed feeding of cone crusher as possible as you can (packed feeding can maximize the...
