size of ball dry ball mill

Ball mill - WikipediaA ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow.The Effect of Ball Size Diameter on Milling Performance | OMICS .Wet milling requires less energy, consumes less power and can achieve a higher degree of size reduction compared to dry milling [6]. Dry milling is however preferred over wet milling due to the difficulty associated with the handling of a wet slurry during milling [5]. Ball mills can be used in a variety of industries such as the.
