Cement grinding Vertical roller mills versus ball mills. cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding.
and an integral separator with industryleading efficiency, the mill consistently uses five to ten percent less power than other cement VRMs. This productivity benefit amounts to millions of kilowatts saved annually for OK mill owners. The OK raw mill is designed according to the same design principles.
This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (28%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill.
After monitoring and controlling the quality of incoming raw material, the area of high activity for quality department to ensure quality mix for smooth production of high quality of cement is "mill feeding system". The system consists of material hoppers/bins, weighing, conveying, venting and mill feeding gate. Mill Feeding Hoppers
