2020-9-22 · Cement grinding is a crucial stage of the flow sheet, where both cement quality and process e ciency are decided. Achieving the required fineness with maximum e ciency is down to the design of the ball mill and how well it runs. An ine cient system can push your energy bill right up, making it a lot more expensive to produce
2020-9-17 · The annual cement consumption in the world is around 1.7 billion tonnes and is increasing by 1% every year [1]. Cement industries consume 5% of the total industrial energy utilised in the world [2]. A total of 40% of the total energy consumption of a cement plant is used in clinker grinding in a ball mill to produce the final cement product [3].
The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FLSmidth ball mill is proven to do just that.
