Even if the cement is not low-alkali cement (below 0.60%), the amount is important for three reasons: Air-entraining agents generally produce more air as the alkali content goes up. Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content.
Cement milling is the process of grinding raw materials (typically limestone, clay, and silica) into a fine powder that can be used to create cement. The process involves feeding the …
Ball mill for cement grinding. 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.
Wilczek: The mill accepts a maximum particle size of about 0.5 mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 10-20 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.

The AirFlow P is a sensor specially developed for measuring air volumes in dusty applications. The AirFlow P determines the air velocity with the help of the dust particles in the process. The evaluation unit (MSE 300) calculates the measured velocity with an entered line area (v x A = m 3 /h). This makes it possible to obtain an air volume in m 3 …
Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high.
