الحصول على السعر· The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
الحصول على السعرAlthough there are two methods of doing a grinding operation, one is wet grinding and the second one is dry grinding. Wet grinding: In wet grinding, during the grinding operation, we sprayed coolant generally water or any coolant to cool the surface so that the longevity of the grinding wheel increases and also we get a fine surface finish. Dry grinding: In this type of grinding process ...
