aug 20, 2015 cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are when acidic water discharged from this process is neutralized, lime is the reagent of choice in order to safely elevate the pH of the effluent stream prior to discharge. another common application is the kraft-pulping process. this most-modern means of making pulp uses caustic soda among other chemicals, to dissolve the lignin.In this process, the hot exhausted air from the lime kiln will preheat the feed limestone to certain degrees so that they can be partially. and then in the calcining process, the partially burnt limestone is calcined for set time period so that it can be burnt thoroughly to make quicklime.
