خبير الاتصالIt is often referred to as a "stirred ball mill"; We can divide it into dry stirred mill, wet stirred mill, normal speed stirred mill and high-speed stirred mill. A useful and simple equation for describing the amount of grinding momentum is m×v (mass× velocity), which allows us to understand why agitation mills are suitable for grinding.
خبير الاتصالRaw mill is the grinding equipment applied in the raw material preparation process.In the wet process of cement production, raw materials should be ground into raw slurry with a water content of 30% – 40%. While in the dry process of cement production, they will be ground into dry powder in a cement raw mill.
