Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.

Mg). The grinding rate was higher for the thin hammer configuration [8,9] reported that the specific grinding energy of uncrushed kernels ranged from 72.3 to 146.7 kJ·kg −1 and from 67.0 to 114.4 kJ·kgfor Turnia and Slade, respectively. The crushing caused a decrease of specific grinding energy in both cultivars. The total specific grinding

As a result, the agglomeration between kaolin particles increased, leading to the increase in the slurry shear stress (i.e., viscosity) and thus reducing the grinding performance significantly. The grinding performance was reduced by the addition of Ca 2+ ions when there was a high clay percentage (40%) and a high solid percentage (70%).
