Controlling the running state of vertical roller mill is also an important measure to deal with liner wear. When the vertical roller mill is running under low load, it is necessary to adjust the feed quantity of vertical roller mill in time so as to improve the grindability coefficient of the ore.

During the installation of the lining plate, it is necessary to excavate and repair the non-conforming parts so that the lining plate can be fully integrated into the working system of the vertical roller mill. After the installation of the lining plate, the relevant staff should carry out repeated debugging and make detailed records to ensure that the fixing bolts in the vertical roller mill have a certain pre-tension force so as to prevent the bolts from loosening during the operation of the vertical roller mill.

In addition, the liners need to be replaced in a timely manner.Generally speaking, as long as the operation is correct, it is necessary to replace the liner once every 12 months, do a good job of checking, and actively adjust the position of the liner according to the actual situation, which can reduce the loss of the liner to a certain extent.
