Cement mill Wikipedia

Early hydraulic cements, such as those of James Parker, James Frost and Joseph Aspdin were relatively soft and readily ground by the primitive technology of the day, using flat millstones. The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is 

Portland Cement The Monarch Cement Company

Portland cement is manufactured from some of the earth's most common minerals, limestone and shale. These materials are ground almost as fine as finished cement and moved through a kiln where they are burned at 2800 degrees Farenheit to form a new material called clinker. A small amount of gypsum is blended with
