Rod mills, how they function Mine Engineer.Com

2012-11-26  Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod

Introduction of Rod Mill Working Principles or

Rod mill operation are as follow. With asynchronous motor speed reducer and small wheel gear connected, the peripheral big wheel gears are driven to gearing-down state. Under the combined effects of centrifugal force and friction force, the grinding media in the shell, rod mills, are carried up to a certain height and then fall down or are

What is the Rod Mill Working Principle?-xinhai

According to the rod mill working principle, we can see that the rod mill is featured with the following advantages: 1. The discharge size is uniformity and high yield. 2. The types are various and reasonable choice depends on the material. 3. Rod mill has dry and wet two forms and needs according to their actual situation to choose.

(1) Rod mill is usually selected in order to prevent over grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine; (2) In two stages grinding, the capacity of rod mill machine used in the first stage grinding is larger than ball mill’s; (3) In some cases, rod mill

Ball Mill vs Rod Mill How To Choose Ball Mill or Rod

The discharging fineness of the material milled by ball mill is between 0.074-0.4mm, and that of the material milled by rod mill is between 0.833-0.147mm. 6. Running Cost. The power consumption of the ball mill is slightly higher than that of the rod mill, and the wear rate is also higher than that of the rod mill.

Dam, near Redding, California for sand production.

Rod Mill Shanghai TON Company

2020-12-9  Rod mills are very similar to ball mills. The rods grind the ore by tumbling within the mill. To prevent the conditions leading to rod charge tangling, theratio of length to diameter is maintained at 1.4 to 1.6. The maximum input size of rod mills is about 50 mm (2 in.) while the size range of final powders is between 3000 to 270 mm (4 to 35 mesh).
