ادامه مطلبRe: 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. This will help to increase the strength.
ادامه مطلبCommon Issue: Coating in cement Silo. It happens due to storage of cement in silos at high temperature (>70 oC), and improper water spray system in cement mill. Strategy to fix the issue: Use cement coolers if cement temperature is higher than specified. Do not store cement for long time in silo.
ادامه مطلبThis is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.
