The steel rod takes regular movement in mill
It is convenient to install and maintain
Even particle size of product, little over grinding
The name of?rod mill?is from the medium in mill is steel rod. ?The rod mill is generally wet overflow type used in the first stage grinding, especially in artificial sand and stone, mineral processing plant and ?power sector of chemical plant.
The?rod mill?is driven by motor with speed reducer and peripheral large gear, or low speed synchronous motor with peripheral large gear. The grinding medium --- steel rod is put into the cylinder which is lifted, and then fall under the action of the centrifugal force and friction force. The materials entering into cylinder form the feeding inlet are grinded by movable grinding medium and discharged out by overflow and continuously feeding.
The grinding medium of rod mill is steel rod which is recognized that the length of rod is less than 7m because the large length is easy to twine. The diameter of rod is 75~150mm
Grinding rod should have enough stiffness and hardness to keep straight, and it should not be too crisp which causes the rod broke into pieces without enough wear. If the rod is too soft, it is easy to bend and twine which makes trouble to clean machine
Rod mill can provide ball mill and pebble mill with feeding materials, while it is able to reduce the lowest rate of unacceptable products which are too coarse or too fine.
The fineness of end products processed by rod mill can reach 2". Open-circuit production can provide 5-10 mesh products; close-circuit production can provide 35 mesh products in combination with screen or other equipment.
Rod mill, the drum-type mill with rod as grinding medium, is applicable to ores, coals or other minerals in wet or dry mode. Rod mill can provide best performance under these following working conditions: open-circuit production can provide end products with maximum particle size of 4-16; close-circuit production can provide 35 mesh products in association with screen or other equipments. Although the rod mill performance can be dramatically enhanced if feed particle size is rendered between 3/4, the rod mill is able to process ores with maximum feed particle size of 11/2.
In wet mode, Rod mill can handle materials with high humidity, which are difficult to be treated by fine grinding and dry screening. As proved by practice, rod mill is able to grind humid material in dry mode, while other mills are probably subject to clogging. In addition, selection the right lining plate can considerably eliminate abrasion of vulnerable parts.
（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 used in the first stage grinding is larger than ball mill's
（3）In some cases, rod mill can replace short head cone crusher
