Every equipment can not operate without bearings, coal ball pressing machine is no exception, bearing is still the main component. However, in the long-term work of bearings, there will be faults and minor problems. Then, how to make the bearings of coal briquette making machine work steadily under long-term operation has become the most concerned problem of users.

The following three points are prerequisites for the stable operation of ball press bearings:
1. Ball press bearings should be designed reasonably and without clearance.

2. No-load test is required before the roller type briquette press is officially operated. When the bearing clearance is observed in the no-load test machine, it should be close to the assembly clearance, otherwise, the bearing may not be able to work.

3. Bearing adopts reinforcement plate and transformer support method, which can change the force situation, so as to reduce the deformation of the stressed parts.

The pressing rolls of ball press are driven by bearings, and the two pressing rolls are the key to the forming of ball press. Therefore, the normal operation of ball press bearings is related to production. In order to obtain more benefits, first of all, it is necessary to ensure that the ball press bearings are perfect and non-destructive.

In the production process of coal briquette making machine, the bearing should not deviate from the track, which requires us to design precisely. Bearings should not be too loose or too tight. If the bearing is too loose, it will easily deviate from the track. If the bearing is too tight, it will cause irregular spherical shape or even the ball will not be shaped.
