Closed circuit grinding consists of one or more mills discharging ground product to classifiers which in turn return the coarse product from the size separation back to the mill for further grinding. In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and size of classifier …

ABSTRACT 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 mo~els of the mill are presented. The first is a high order model which is used to develop a simplified continu­ ous model.

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 …

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.

Efficient closed-circuit systems, because of their tight particle size control, lead to cements with relatively narrow particle size distributions (i.e. for a given mean particle size, they have fewer large and small particles). This is of advantage in that it maximizes the strength-production potential the clinker, because large particles are inert.

An electric circuit is a closed path through which the current flows. an electric circuit comprises a switch, a bulb, a cell, etc.when the switch is closed, the circuit is complete and current starts flowing through it. on the other hand, when the switch is open, the circuit is open or incomplete hence, current stops flowing through it.
