Cement grinding ball mill problem Grinding

Why cement grinding ball mill is floating towards the Gear box (MAAG) which has resulted the damage of the second stage of gear box. As we have replaced the gear box now but still we are unable to find out the solution how to control the mill which is continue its floating towards gear box. Any sugg

Development of Fuzzy Logic Controller for Cement Mill

ball mill circuit. The cement ball mill circuit should fulfill the rules of indestructibility of matter for steady-state operation [7]. The following equation exists under steady state condition: Fig.1: Ball mill circuit m =x (1) The equation (1) can also be written as m = x =r + g =v + g (2)

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.

Identify and resolve mill ventilation problems in cement

That is what it is designed to do separate coarse and fine cement. If the separator runs faster, it rejects more (coarser) material back to the mill, leading to a finer finished product. In old open circuit mills this is not possible so the only option is to reduce the mill feed. Open circuit mills

CEMENT PLANT TALK-001

Cement Mill Common Issue: Higher cement temperature, Mill tripping under high cement temperature or mill outlet temperature is not an uncommon in cement mills. It happens in majority of cases due to high clinker temperature and the other reasons could be insufficient mill venting and insufficient or faulty water spray system.

Soft Constrained MPC Applied to an Industrial Cement Mill

mill circuit. Sanchez and Rodellar (1996) control the cement mill circuit using adaptive predictive control. The cement mill grinding circuit resembles to some extent grinding circuits used in the mineral industry. Model based control technologies for such grinding circuits in the mineral processing industries have been surveyed by Pomerleau et al.
