Milling product and formulation. A ground calcium carbonate powder from IMERYS, mean particle size of D50 = 17 µm was used as the milling product. The slurry was a water base which included a dispersant aid. 'Dispex N 40' (1 weight-% based on solids). The following formula properties were achieved: solid content 50.
The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product. Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a.
In spite of a great number of studies in the field of fracture schemes there is no formula known which connects the technical grinding work with grinding results. To calculate the needed grinding work against the grain size changing three half-empirical models are used. These can be related to the Hukki relationship between.
