Super P slurry was also made under the same conditions, using Super P dispersion solution. Each slurry was casted on a 20 µm Aluminum foil using a doctor blade and dried in the oven at 60 (^circ{rm C}) for 24 h. To make uniform thickness, the dried slurry was additionally pressed using a roll press and dried in a vacuum oven at 80 (^circ{rm C}) for 24 h.

Note the last two items are variable (well the mill charge is too due to wear and new media added, as well as mill linear wear). This would then need to be integrated both cross sectionally and longitudinally. Both of these would then need to be calculated at start up sthrough normal operation. This is a very complex method.
