As the mill rotates, the steel balls drop onto the quartz and pulverize it into particles as small as 10 to 100 microns. For example, the Disperex Planetary Ball Mill by NETZSCH grinds quartz down to a D97 of 10 microns. Ball mills are effective at grinding quartz materials to an ultrafine powder grind size suitable for use in white ware ...
