Re: The lumps in the cement. The following possible measures will reduce lump formation in cement silo: 1.Since moisture in cement is mainly through dehydration of gypsum during grinding, it may be attempted to reduce moisture concentration in cement by increasing cement grinding temperature in the mill (max. 115 deg Cent.) so that extensive dehydration takes place in mill itself and moisture ...

Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling .
