Cement Manufacturing Process What is Cement made of.Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
Dry Process for Manufacturing of Cement.Cooled clinker and 3 to 5 percent of gypsum are ground in ball mill to required fineness and then taken it to storage silos from where the cement is bagged. The equipments used in the dry process kiln are comparatively smaller. The process is quite economical. The methods are commonly employed for direct control of quality of clinker.

Cement FormationA Success Story in a Black Box High.Cement production has been subject to several technological changes, each of which requires detailed knowledge about the high multiplicity of processes, especially the high temperature process involved in the rotary kiln. This article gives an introduction to the topic of cement, including an overview of cement production, selected cement properties, and clinker phase relations.
How Cement Is Made.Clinker comes out of the kiln as grey balls, about the size of marbles. Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency.
US4001031A Process for making low alkali cement clinker.The potential K 2 O content of cement clinker due to the presence of potassium compounds in the raw feed mix is substantially eliminated by introducing an active agent into the kiln along with or in conjunction with the fuel used to fire the kiln. The active agent is effective to convert K 2 O to KCl and preferably is a chlorinated organic waste product burned along with the fuel.
What is the manufacturing process of Portland Cement.During this process, these materials partially fuse to form nodular shaped clinker by breaking of chemical bonds of the raw materials and recombined into new compounds.
