The application required that the mill be designed with a shaft seal for grinding under inert gas. The specially designed mill includes a temperature probe to measure the temperature in the grinding chamber. The customer required a tungsten carbide-faced tank with tungsten carbide-sleeved agitator arms for this specific application.
Union Process' mill is equipped with a five horsepower variable frequency drive to allow for the variance of the shaft RPMs for experimental purposes. It also includes a bar grid and ball valve so one can discharge the slurry while leaving the media behind. Special discharge vessels are available in case one needs to discharge the slurry under inert atmosphere.
