Tungsten carbide, zirconium oxide, and stainless steel are the three different kinds of materials for grinding jars which ensures the preparation of samples in a contaminationfree environment. The availability of tungsten carbide is in a 50 ml jar ...
WhatsApp: +86 18203695377A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.
