The dry powder and dosed agent are put into modifying rollers simultaneously. With high speed rotation, the materials and agent is running in the form of fluidizing vortex. The modification is completed with the heat generated by high speed shearing, colliding and friction among the rotor, stator and the powder.
How often does the grinding roller of vertical roller mill
Since the grinding roller is rotated by the rotation speed to achieve a good grinding effect, the friction received by the grinding roller is very large. As the vertical grinding running time increases, the thickness of the grinding roller becomes smaller as the friction becomes smaller. After the thickness of the roller is less than 10 mm, it will not work properly. At this time, the roller should be replaced.
