Medium-speed mill is an important auxiliary dynamic machine in the thermal power plants. To mitigate the vibration, the spring vibration-isolated foundation is normally used to support the mill. A spring vibration-isolated foundation for medium-speed mill is typically comprised of upper and lower bedplates and spring isolators.

Medium-speed coal grinding is not suitable for grinding harder coal. In large-capacity coal-fired boilers, bowl-type medium-speed mills are used more; high-speed coal mills are especially suitable for grinding high-moisture lignite and bituminous coal with high volatile content and easy to grind.

Medium speed coal mill refers to the coal mill with working speed of 50 ~ 300r/min, which is the preparation equipment of pulverized coal for boiler fuel in the power system and the professional equipment for preparing auxiliary materials for blast furnace ironmaking. Medium speed coal mill is the most important large equipment in coal to oil to powder system.
