Saving power
The rods have a screening effect on the materials during movement, which can make the large particle material be lifted to the high position of each layer and concentrated to the place with strong crushing ability. Therefore, the working efficiency of the rod mill is high and the power consumption is low.

Few over-crushing
When the ore is ground by the steel rod, it is first crushed into coarse particles and then ground into smaller ones, thereby reducing the risk of over-crushing.

More uniform discharge size
Rod mill changes the surface contact of traditional ball mill to line contact.
When the rod rotates and rises along with the liner, the coarse particles are sandwiched between them, allowing the fine particles to pass through the gap of rods, which is conducive to crushing coarse particles, so the coarse particles are concentrated in the place where the grinding medium hits.
Therefore, the rod mill product is more uniform, and the over-crushing is lighter. It is suitable for ores with different hardness (Mohs hardness 5.5–2).

Adjustable discharge fineness
The particle size of the material produced by the rod mill can be adjusted according to the needs of users, because there are a fineness control device and a screening device for discharging inside the rod mill. These two devices work at the same time.
Smaller mineral particles can be obtained by adjusting their size, so the size of the ground particles can be effectively guaranteed.

Rod mill makes tube run with the help of the reduction gears drove by dynamo or the low-speed synchronization electrical machine. There are steel rods in the tube which are thrown at a certain high speed by centrifugal and friction force and then fall.
The ground material enters into the tube continuously and is crushed by the moving steel balls. After that, they are discharged from the machine naturally and will start the following working process next.
