Vertical grinding mills often encounter bearing damage during use. Since updating the bearings is a very troublesome thing, the user wants to minimize the damage of the bearings. Before the new material or manufacturing process of the bearing is produced, we can only start from some small aspects of the machine itself, and the details determine success or failure. Therefore, it is recommended to operate .

The vertical roller mill grinding system is a kind of semiclosed operation system. There cannot have connecting in vertical roller mill around parts and it is for this reason: the hot blast stove hot wind cannot flow out, or it will have dangerous and cause the power consumption. The draught fan will take out the hot wind from the hot blast stove and it is used to dry the materials. It cannot be the outside wind or the .

The air volume of the vertical roller mill is controlled by the fan, and the fan plays a vital role in the operation of the vertical roller mill.
