The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
estimated through a simple heat balance that in ball mills only 10% of the energy is used to increase cement fineness, the rest being dissipated basically in form of heat. . having grinding and separation units gathered in the same machinery, gas flow is higher, allowing the use of material with higher humidity content.
Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
Laboratory Mills A grinding mill is a unit operation designed to break a solid material into smaller pieces. There are many different types of grinding mills for laboratory and many types of materials processed in them. The grinding of solid matters occurs under exposure of mechanical forces that trench the structure by overcoming of the interior bonding forces.
