Two main reasons for the damage of the pressure rod bearing of wood pellet mill

             1, lack of oil, burned, characterized by the pressure roller disassembled out, found that there is no oil in it, the inner wall of the pressure roller shell is burned to turn blue. 2, is the bearing running not parallel.
             Characterized by the pressure roller as a whole is not tightened to cause the bearing support frame to fall apart. Wood chip pellet machine in operation, the pressure stick bearing attention to check matters. When the machine is running, the automatic greasing system will be debugged to 30 minutes to inject oil for about 2 minutes, usually before starting the machine, observe whether there is sufficient oil inside the greasing machine, such as not replenishing, the lack of oil inside the pressure rollers, resulting in the bearings burned out. Every day to open the granulation chamber, surface observation of the pressure roller gland is loose.
