·Several comminution laws have been proposed to link the consumed energy to a characteristic particle size of the powder The popular models are those of Rittinger [4] Bond [5] and Kick [6] While the Bond and Kick models are mostly employed for coarse and intermediate size grinding the Rittinger model is better suited for fine comminution [7] This model assumes
Depending on the origin and properties of the pre ground raw material it is possible for example to produce finenesses of μm on the 500/800 TDG at a throughput of up to t / h In addition of water or silane by spraying into the grinding container is required already a normal mode of operation Wet grinding with media mills
The influence of ball mill grinding on the color and particle size properties of talc and smectite from white bentonite was studied and compared with fine grained calcite from chalk [36] However
·As the main raw material for ceramics and coatings black talc contains high contents of organic carbon and quartz which deteriorates the whiteness and purity of calcined talc In this work calcined talc powders with high whiteness and purity have been prepared by the milling and reactive calcination of black talc with magnesium precursors Black talc and
