The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closed …
In cement grinding process, the raw materials like clinker, gypsum and fly ash are feed into grinding mill. The sound sensor is installed as near as possible to mill's wall. The sound generated in grinding mill is given as actual input to comparator and desired input value is fixed based on fineness of cement.
We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.

Process parameters Kiln Speed should be such that volumetric loading is within the range 10-15% and heat transfer is maximized. Pre-calciner kilns generally rotate at 3.5-4.5 rpm. Under normal conditions, kiln should be run with as high rpm as possible. Higher kiln rpm improves clinker mineralogy and grindability.
Our reference plants for cement raw material and clinker grinding show that a capacity increase up to approximately 10 % and a reduction of specific energy consumption up to approximately 10 % may be achieved. ...
