Portland cement clinker in Portland cement manufacturing

  • Portland Cement Manufacturing – Ordinary Portland

    Portland cement derives its name from Portland, England, in many cases, also called silicate cement It is a kind of hydraulic cementing material made of calcium silicate cement clinker, limestone or blast furnace slag (less than 5%), and an appropriatePortland cement clinker overview Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C 1500 °C The nodules are ground up to a fine powder to produce cement, with a smallPortland cement clinker Understanding Cement2 The limestone is combined with clay, iron ore and sand It is then ground in a crusher and fed into 3 Next, the fine powder is heated as it passes through the PreHeater Tower into a large kiln In the kiln, the powder is heated to 1500oC This creates a new product, called clinker, which resembles pellets about the size of marblesClinkers and Portland Cement Manufacturing Process

  • What is the manufacturing process of Portland Cement

    It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 23% percent of GYPSUM Several types of Portland cement are available The most common, called ordinary Portland cement (OPC), is grey, but white Portland cement isClinker History & Traditional manufacturing In 1825 the Portland cement clinker was first made in a rectifies form of the traditional static limekiln The undeveloped, eggcup shaped lime kiln was equipped with a beehive formed an extension to rise draft and therefore attain the higher temperature needed to make clinker For almost half a century, this project, and minor adjustments continuedWhat is Clinker? (Meaning, History, Manufacturing· The invention relates to a method and a plant for manufacturing mineralized portland cement clinker The method and plant provides for preheating, calcining, burning and finally cooling the clinker The mineralizer may eg be gypsum, fluorine, or a waste product containing these or other mineralizers The mineralizer is added to the feedstock after the feedstock has been fed to the processUSA Method and plant for manufacturing
