1972-6-1 The design of a control system for a closed circuit mill is developed. The control strategy is to estimate the point of instability for the unit and to control the mill at a constant value away from this point. Several models of the mill are presented. The first is a high order model which is used to develop a simplified continuous model.

Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding ... Get Price

2004-1-14 If open and closed circuit experiments are compared in terms of specific energies of the products of equivalent Blaine surface area, closed circuit experiments uses more energy than the open ones. Closed circuit experiments resulted in a Blaine area of 4000 cm 2 /g at a specific energy consumption of 100 kW h/t. However, the same surface area can be achieved at 55 kW h/t for open circuit stirred 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.
