Mortar – Ideal temperatures for the placement and curing of masonry mortar is the range of 70 F + 10 F. In cold weather (40 degrees Fahrenheit and below) mortar materials need to be heated, otherwise the mortar is likely to exhibit slower setting times and lower early strengths. Water acts as a lubricant in the plastic mortar and is.
After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed.
