I'm obtaining inconsistent rheology results with some compounds and I'd like to make mixing and milling improvements. Generally speaking, what KPI's do you prioritize to obtain consistent batch-to-batch mixing, milling, and rheology?
On the banbury mixer, a temperature probe sticks inside the mixer a couple inches. I have a 2-pass compound that is very high viscosity that regularly snaps the probe in half after the masterbatch is added. I've tried adding the masterbatch in two charges, and it's reduced the occurrence, but...
