A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.

The grinding process consumes the most energy in the cement production, its energy consumption accounts for more than 70% of the total power consumption in the whole process of cement production. There are three main grinding processes in the cement production: raw meal grinding, cement grinding, and raw coal grinding.

The preheated cement raw meal (temperature is about 820 ~ 860℃, not exceeding 860℃), a certain amount of fuel, and hot air (kiln tail flue gas or tertiary hot air) are fed into precalciner at the same time. After entering the calciner, the fuel and raw meals are dispersed by high-speed airflow and in a suspension state at about 900℃.

3. Raw Meal Homogenizing: The raw meal homogenization is a key factor for stable clinker calcination. 4. Preheating and Decomposing: The preheater is used to preheat as well as decompose raw meal. So the length of the rotary kiln is effectively shortened. And the raw meal can fully exchange heat with the hot gases from the kiln.
