Fault causes and solutions of roller press - bearing ...

Mar 26, 2019  The four bearings of the roller press are the key parts of the whole machine. The grinding force of the crushing material of the roller press is applied to the bearing block by the hydraulic cylinder to push the roller and the motor is driven to rotate the press roller, which needs to be implemented by the bearing. Once the bearings are broken, the roller press has to be shut down.
