However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill. In the traditional Blaine SSA Fineness method, the fineness of cement is determined using an air permeability method in which dry air is passed at constant pressure through a compacted cylindrical bed of cement.
Feb 10, 2016· VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.
particle size distribution curve. By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6: B It should be noted, however, that operation to achieve a wide particle size distribution (low nvalue) has a cost.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

How the mill achieves uniform particle size To achieve a uniform final particle size with minimal fines, the roller mill must have the right roll surface, roll speed ratio, and roll gap for your application. Roll surface. Typically, the roll surface is corrugated rather than smooth to achieve efficient size reduction, as shown in Figure 3.

of the particle size. Thanks to the integrated separator (classifier) the grounded material is separated after each passage. In comparison to a ball mill (with external separator), the separation is sharper. Therefore the particle size distribution (PSD) of the cement has the tendency to be narrow ( high n'' according RRSB). This
