Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.

To maintain the maximum amount of through put that the grinding mills can handle it is necessary to keep what is termed as the "MEDIA RUNNING LOAD" to its maximum. This is the amount of grinding rods or balls that are in the mills. As the mills tumble and turn the grinding media wears away until the mill charge is too low to maintain the grind.
