Clinker Grinding

In an open-circuit system, the feed of incoming clinker is adjusted in such a way that it achieves the desired fineness of the product. In the present day, open circuit has become obsolete. However, in a closed-circuit system, coarse particles are separated from the finer product in a separator and then brought back to a mill for further grinding.Get price
