Re: Cement separators. I need to understand your milling circuit better to make an informed comment. However it sounds to me that the four separator dampers are being opened to cool the cement temperature. This will contribute to cooling the mill exit temperature but only because the reject returns from the O-Sepa will be at a lower temperature.
