Ball Mills

Ball mills have been manufactured for over 150 years, and have become an industry standard for dry minerals grinding. A ball mill is still the preferred solution for many types of dry grinding duty. A ball mill consists of a rotating horizontal cylinder, containing a cascading grinding media, typically steel or ceramic balls, in the range of 10 to 100 mm diameter. The grinding mechanism takes place within the falling and sliding grinding media. The feed material enters at one end of the ball mill and travels horizontally through the grinding media, discharging at the opposite end of the mill passing through a discharge grate and normally to a high effeciency air classifier for product classification.
