control philosophy of closed circuit cement mill

Apr 24, 2021 Cement mill . Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

Automation and Control in Cement Industries

Figure 4. Typical cement grinding mill A closed circuit consists of three main parts: the ball mill itself, the elevator lifting the mill product to the separator and the separator returning the oversize material to the mill as reject. The separator splits the final (fine) product out of the system. 3. Control

The cement mill

In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.
