grinding unit. Raw material and slag grinding In the beginning the RP was used only in combined mode with either a ball mill or even with impact hammer mills. The first raw material grinding circuit in finish mode based on RPs was installed in the 1990s, and since then, this configuration has become the state-of-the-art technology for

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane). Surface texture is one of the important factors that control friction ...

Finish Grinding. In the finish grinding, clinker is mixed with gypsum and other minerals, such as blast furnace slag, according to the specifications of desired end products and are ground, or milled, to achieve required particle fineness. Finish grinding accounts for nearly 40% of the electricity use in cement production.

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
