The vertical roller mill separator and the louver ring are one of the important internal parts. When they are working, they will also encounter some problems. The solution of these problems is an important condition to ensure the smooth operation of the machine, and then for these parts The maintenance of these two parts is also very important, so that failures can be prevented in time. In this article, we are going to analyze the maintenance of these two parts.
In the interior of the vertical roller mill, the material after the sorter is ground and dried enters the part along with the air flow from the lower part for sorting operation. The purpose of sorting is to obtain a better quality of the finished product. There are moving and static blades, and the welding must be firm, otherwise it will cause accidents such as shutdown.
The maintenance of this part is divided into the inspection and repair of the moving blades and the static blades. When the moving blades are overhauled, they need to be vibrated with a hand hammer one by one. See if there is any movement of the blade. If so, it needs to be fastened, marked, and welded and strengthened.
If severely worn and deformed blades are found, they need to be removed, and new moving blades of the same size shall be installed according to the requirements of the drawings, and they shall be weighed before installation to prevent loss of balance. When the stationary blades are overhauled, they need to be overhauled.
