What are common colloid mill troubleshooting steps if the product isn’t fine enough?

Common colloid mill troubleshooting steps for insufficient fineness include checking whether the rotor-stator gap is set too wide, verifying the rotor is spinning at the correct speed, inspecting for excessive wear on shearing surfaces, and confirming the feed rate isn’t overwhelming the mill’s processing capacity. Reviewing formulation viscosity and pre-mix quality can also reveal whether the issue originates before the milling step.
