An inefficient ball mill is a major expense and could even cost you product quality. 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 FL ball mill is proven to do just that.
Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …

Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.
