The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills The increased frequency is due to the Increase in charge volume 35 – 40 versus 5 – 10 higher mill speeds and the larger number of balls per unit charge weight...We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, briquette machine, mining, metallurgy and other related equipment. which can crush all kinds of metal and non-metallic ore, also can be dry grinding and wet grinding.If you are interested in our products or want to visit the nearby production site, you can click the button below to consult us.Welcome to our factory to test machine for free!
