| In coal power plant, coal mill is an important part of the pulverizing system, which plays a great influence on the boiler outlet and the unit load, the safe operation of coal mill is closely related to the installation quality. In China, there are more than one hundred coal mill made by METSO. Based on the practice of installation and commissioning of coal mill, much attention was paid on the installation techniques of baseplate and large scale gear, the proper procedure and method were put forward by the author. To obtain the minimum error and improve the meshing effect, the horizontal adjustemt by using pad iron and the axial float of large scale gear by adjusting the thichness of stainless steel gaskets on the bolts for large scale gear were performed. All the work had been done provide technical support for safe and low noise operation of coal mill. In addition, all the work had been done is useful for the maintenance of coal mill.
