The effects of grinding media shape on the position of the shoulder, and toe and the mill power (Mill diameter = m, Mill length = m, and J = 15%) (Lameck et al., 2006). The order of effecting on the power draw of the mill, shoulder, and toe position for three different types of grinding media shapes are presented in Table 3 .
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.
However, we cannot totally exclude the formation of diglycerol in the grinding process since very small amounts of glycerol are used in the real production process (which makes the ratio between the catalytic species and the substrate very high) and localised overheating may occur in the ball mill. The spent clinker catalysts recovered from ...

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.
