How Portland Cement Is Made Manufacturing Process Of

Aug 31, 2009 Portland cement can be made by following two different processes a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85 of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.

US5572938A Oxygen lancing for production of cement

Us5572938a Oxygen Lancing For Production Of Cement

Oxygen is lanced into the main combustion reaction of a cement kiln to increase heat transfer to the clinker bed and to increase clinker production. Oxygen is separately lanced along the floor, i.e. the lowest wall of the kiln, to delay mixing with the flame to provide deep staging. The deeply staged oxygen flow is adjusted frequently to control emissions and stabilize the burning zone while ...
