Mill construction, i.e. in ball mills and dry mills
SSiC, SiSiC, Si3N4 and ZrO2
- high wear resistance due to high strength and hardness
- high chemical corrosion resistance
- low density, i.e. small mass moment of inertia
- no metal impurities
In food and drug industries it is most important that no impurities arise from the tools during the milling process; therefore it is preferential to use ceramic mills, with excellent wear and corrosion resistance properties.
