Re: Low temperature cement grinding. With the low residence time and low temperatures in vertical mills for cement grinding gypsum dehydration will not be completed. That might well affect the setting time, workability and compressive strength development of the cement.
Low temperature cement grinding - Page 1 of 1. Re: Low temperature cement grinding. Hi Gio, Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills, the mill outlet temperature is around 80-85 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution.
