    History. 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 often as hard as the millstone material. Coal crusher is the status quo of the coal industry launched a new exclusive equipment high efficiency and low consumption are its salient features.
