Wet Milling Process Reduces Particle Sizes
Zinc and titanium dioxides, talc, salts, talcum, calcium carbonate and other solids need to be effectively ground down to manageable sizes to create better dispersions. A dispersion is similar to that of a wet slurry that involves processing the solids into a finer suspension.
When wet milling equipment is used to make these dispersions, it’s important to isolate the mechanical seal from the process slurry. Sonic offers a Seal Flushing system that provides improved performance and simplicity above the age-old pressure pot units that resemble something off a world war sub. Instead of using a completely pressurized vessel with a hundred bolts holding it together, we offer a simple vessel that is not pressurized and a PD pump that pressurizes the seal chamber by pumping through an adjustable valve that generates pressure. This way, only the seal chamber sees the pressure instead of the entire piped system and vessel. The vessel is jacketed to provide cooling and contains instrumentation such as level sensor and temperature sensor to monitor flushing fluid. These are clean, sanitary assemblies using stainless tubing and sanitary connections.
