Improvement of cement performances through the use of ...Vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills, in some cases up to 300 t/h. Empirically, It can be estimated through a simple heat balance that in ball mills only 10% of the energy is used to

Fineness Test of Cement; Its Apparatus, Procedure.And after testing, you found the retained weight of cement on the sieve, Let it be 65 grams (w2). Now put the values in the formula; % of retained weight of cement = (65/1000) x 100. SO, the result of a fineness test of cement will be % which is below the IS value (10%) and hence cement is in good condition.

Manufacturing of Cement By Dry and Wet ProcessGrinding: The cooled clinkers are finally ground in ball mills or tube mills. Also, the gypsum is added during grinding about 24% . The gypsum acts as a retarder and so allows the cement to mix with sand or aggregate and to be placed in postion. it increases the initial setting time of cement.

All Pakistan Cement Manufecturars AssociationCement milling. The cement mills use steel balls of various sizes to grind the clinker, along with a small quantity of gypsum to a fine powder, which is then called cement. Without gypsum, cement would flash set when water is added and gypsum is therefore required to control setting times.
