For shallow-cut grinding of cast iron using a vitreous bond aluminum oxide wheel, the energy partition using a small wheel depth of cut of 10 μ m was estimated as 84% for dry grinding, 84% for MQL grinding, but only 24% for wet grinding. Such a small energy partition with wet grinding can be attributed to cooling by the fluid at the grinding zone.

I'm guessing you're set up to vent when the wet bulb condition in the kiln is over your setpoint of 155. With 165 dry and 155 wet, you are setting conditions in the kiln around 77% RH, which will give you very slow drying. Decrease your wet bulb drastically, like to 140 or so, so you have a large depression, which will vent off some moisture.
