High classifying efficiency means that those qualified grains can be discharged timely and efficiently,while low classifying efficiency means that most qualified grains are not discharged and sent to the ball mill for re-grinding, which is easy to cause over-grinding and thus affecting the separating effect.1. According to the discharging method, the ball mills divided into grid type and overflow type. 2. According to the shape of the barrel, divided into short cylinder ball mill, long barrel ball mill, tube mill and cone mill. 3. According to the grinding media, divide into steel ball mill, rod mill. 4.
Ball mill is a key equipment for grinding materials. thus grinding ball mills are widely used in the mining beneficiation process, and it has a wide range of suitable grinding mineral and can works on wet and dry grinding processing. our JXSC's ball mills are perfectly used for ores such as gold, iron, zinc ore, copper, etc JXSC Mining produce reliable effective ball mill for long.Aug 31, 2021 A ball mill is a reguler tipe of grinding mill. It has a horizontal, slightly inclined silinder filled with balls of metal or stone. These balls grind materials by impact and friction with the rolling balls. Ball mills have longer length and small diameter, and have a length between 1.5 and 2.5 times its diameter.
