## PROCESS CONTROL FOR CEMENT GRINDING IN

The power ingesting of a grinding process is 5060% in the cement production power consumption The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills The process variables in cement grinding process using VRM are strongly nonlinear and having large time

## The Effect on the Performance of Cement Grinding Aid

Keywords: Cement grinding aid, Fineness, Compressive strength, Size distribution Abstract In this paper, By choosing four kinds of grinding aids better onecomponent, The grinding aid of cement grinding aids is determined by orthogonal optimization By adding different inorganic reinforcing components, Developed a cement grinding

## Page 1 Ball Milling Theory

Grinding Theory: There are a lot of misconceptions about what goes on in a ball mill We know that a drum filled with heavy metal objects will grind powder when it is rotated, but how exactly does this happen? Some people think that the powder is pulverized against the sides of the drum as the media roll over top of it
