The Effect of Grinding Media Performance on Wet Milling of Calcite 381 Figure 1. XRD pattern of feed calcite Moreover, as dispersant, an amine-based grinding aid, which is commonly used in the calcite industry was selected. The density of this chemical is 1.13 ± 0.02 g/cm3, and it was used to disperse the particles of CaCO 3 in water.

The nature of grinding aids means that they promote the formation of dust because they reduce the agglomeration of the finest particles (see Figure 3). In certain cases, the filter and/or the hopper of the bag filter can become overloaded. This can lead to the wrong supposition that the grinding aid chemically attacks the filter cloth.

The transformation of calcite to aragonite by grinding has been studied using r-ray diffraction methods and electron microscopy. Grinding at room temperature produced a partial transformation to aragonite. The transformation curve was characteristic of a nucleation and growth process. It is postulated that the nucleus is formed by atomic

applied grinding knowledge to optimise the raw meal burnability and reduce the thermal energy requirements. Industrial plant trial Table 1 shows some of the key data from the raw mill during the baseline and Fosroc 360RM trial period. As expected, when using a grinding aid, the mill output was increased by ˜ve per cent in this short trial.
