Vertical Raw Mill for Cement Raw Meal Grinding in

Vertical raw mill is widely used in cement industry. In the process of cement production in cement plant, cement raw meal needs to be ground by grinding equipment before calcination. Cement raw meal includes limestone, gypsum, silica, clay, fly ash and other components. Because these materials are mixed together and have special properties, so there is a high requirement for the material suitability

Cement kiln - Wikipedia

In this process, the steps of raw material processing, fuel preparation, clinker burning and cement grinding constitute major emission sources for particulate components. While particulate emissions of up to 3,000 mg/m 3 were measured leaving the stack of cement rotary kiln plants as recently as in the 1960s, legal limits are typically 30 mg/m 3 today, and much lower levels are achievable.
