our OK mill grinding solution skilfully comminutes raw material, cement and slag. you can easily adjust it to grind any feed material and produce multiple cement types in the same mill. due to its highly effective drying performance, the OK mill is the natural choice for under ideal working conditions, raymond mill consumes less energy than other ordinary grinding mills. for example, the mtm medium-speed grinding mill only consumes 1.wh when yielding a ton of materials and 1.wh when feeding a ton of materials. its electricity consumption is lower than that of ball mill at the same level by over 60%.
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At the raw meal largely decarbonates; at the temperature is 1000 1200 and intermediate compounds are forming and at the burning zone, clinker nodules and the final clinker minerals form.jun 20, 2015 after cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. the cement mill grinds the clinker to a fine powder. small amount of gypsum a form of calcium sulfate is normally ground up with the clinker. the gypsum controls the setting properties of the cement when water is added.
