Rod Mill | SpringerLink

In some cases, the rod mill can replace the short-head cone crusher for fine crushing. When the two-stage grinding process is adopted, if the first stage needs to be ground from 6–20 mm to 1–3 mm, the rod mill is used as the grinding equipment of the first stage, thus it has a larger production capacity and higher efficiency.

Ball Mills

One stage rod mill grinding is therefore suitable for preparation of feed to gravimetric ore dressing methods, certain flotation processes with slime problems and magnetic cobbing. Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least 1.4.

Rock Crushing Process in Mining

Tumbling mills (ball mills, rod mills, etc.) utilize both continuous-pressure and impact mechanisms. Blasting, explosive shattering, and decrepitation (fire-setting) are tension-type crushing operations; all three are relatively unimportant as crushing operations, although blasting is, of course, pre-eminently useful in rock excavation.

How to choose Rod mill and ball mill?

What's the Difference Between Ball Mill, Rod Mill and SAG Mill?

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption …

Determining the Bond Efficiency of industrial grinding …

dard Circuit, assume 2.44 m diameter overflow mills, and use a rod mill F80 of 16,000 µm and a rod mill P80 of 1,000 µm. Note that—in order for no correction factor for ball mill product fineness to apply—the ball mill circuit P80 should be no less than approximately 70 µm (Bond, 1962). This

Ball Mills vs Rod Mills

Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..
