I am reviewing pigment dispersion process data, and I have found inconsistent discharge temperatures during wet Bead Mill operation. Have any of you experienced a strong correlation between slurry viscosity (it seems) and the effectiveness of the cooling jacket? We are trying to establish if the root cause of the inconsistency is either from insufficient mechanical seal pressure or the total energy input. I would appreciate any technical input on successfully managing residence time without overheating the product (for example, using smaller zirconium grinding media).
