where V 0 and V s [g/cm 3] are the cable volumes before and after the swelling test, respectively.. Wet ballmilling tests using nbutyl acetate, acetone, and ethyl acetate. To conduct the wetmilling tests, a stainless mill reactor (length, 160 mm; inner diameter, 160 mm) was loaded with the cable sample ( g), selected solvent (100 mL), and suitably sized balls.

What's more, the energy consumption of raw material grinding in the wet process is reduced by nearly 30%. Disadvantages: the heat consumption of the wet process is too high, usually between J/kg and the consumption of ball mill vulnerable parts is also large. Compared with other processing methods, the clinker manufactured by the ...
