Rod Mill

Rod Mill

The rod mill is composed of a cylinder body of the grinding body is named for the loading of steel bar, rod mill is generally used wet overflow type, can be used as a class open circuit grinding use, are widely used in the artificial sand and stone, ore dressing plant, chemical plant in the power sector level grinding. Rod mill are dry and wet two types to choose, the user can be chosen according to their actual situation. Rod mill by the motor through reducer and the surrounding large gear drive or by low speed synchronous motor directly through the surrounding big gear reducer, driving the rotating cylinder. The cylinder body is equipped with the appropriate grinding medium steel bar. Grinding media in the role of centrifugal force and friction force, was elevated to a certain height, the drop or drain fall down state. Be ground material from the feed port continuous enter the cylinder body, was crushed in the movement of the grinding medium, and through the overflow and continuous ore power products will be discharged out of the machine, for the next period of process operation.

Rod mill adopts advanced controllable discharging technology, combined with the actual grinding materials should be equipped with appropriate grinding body, in the traditional contact contact into line with the grain size, more uniform, more productive, and rod mill reasonable price, widely used in grinding operation, chemical industry, metallurgy, refractory and glass industry uniform the finished products after grinding degree requirements are relatively high, in recent years also used for sand sand making building.

Performance characteristics of rod mill

Characteristics of rod mill is in the process of grinding, the grinding medium and the ore is line contact, and thus has a certain role in the selective grinding. The particle size of the product is more uniform, crushing the ore grain less. For coarse grinding, ball mill processing capacity than the same specification of rod mill. And vice versa. The rod mill can be easily changed by adjusting the discharge granularity, built-in fineness control device, a material can be added to a screening device, two control, ensure that does not produce too abrasive and can not make a nonconforming product mix product. Rod grinding particle size characteristics and rod milling ore status. When the bar fight ore, first is the name of coarse grain, then grind small mineral particles, thereby reducing the risk of excessive comminution. When the rod along the lining board turn rise, sandwiching therebetween a coarse, like bar screen, let fine from the seam between through the bar, which is also conducive to the minced coarse grain, and the coarse concentrate on grinding media blow place. Therefore, the product of rod mill is uniform, smashing the lighter.
