The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in realscale grinding plants. In fact, laboratorygrinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement ...

new vertical mills were planned from the outset, but other options would have been possible. For example, clinker could be ground in an existing ball mill and GBFS in a single vertical mill because the advantages are relatively higher for slag grinding than that of clinker grinding. While the use of two vertical mills would improve grinding ...

Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.

For ball mills, it is more efficient to reduce the size of large particles prior to the mill, using physical means such as a hammer crusher, pregrinder, or a roll press. Fine clinker is less of an issue in a ball mill, since the material simply passes through to the second chamber for fine grinding, although this can reduce the impact of the ...

The process of grinding the raw mixture and the additives is achieved by a pressure exerted by the rollers on the grinding table. A fan draws gas flow from the preheating tower to feed the VRM as shown in Fig. 2. Then, a second fan located downstream of the mill draws grinded material to the dynamic separator located above the mill.
