How to reduce the wear of the roll skin of the double roller granulator
Severe roller surface wear will affect the production efficiency of the double roller granulator and the finished product size of the material. If it is serious, it will be necessary to stop the machine and replace the new roller surface. How to reduce the material to the roller surface in the process of using the double roller granulator in many ways What about the wear?
The double roller granulator is sometimes equipped with a grinding wheel on the machine frame. When there are pits or grooves on the roller surface, the roller surface can be ground and repaired on the machine without removing the roller surface, or directly on the roller surface. Repair, which requires a build-up welding device on the pelletizer. Some roller granulators are equipped with roller automatic axial reciprocating movement device, so that the roller surface wears evenly.
In addition, the wear of the roller surface will increase the discharge port, so the movable roller needs to be adjusted. When adjusting, you need to pay attention to keeping the two rollers parallel to each other to prevent skew. The movable roller is installed on the rocker arm or the double roller organic fertilizer granulation machine with hydraulic compensation device. When the movable roller moves, it will automatically ensure that the axes of the two rollers are parallel.
