Grinding process: Rod mill is used in the grinding process to grind ore. Because the particle size of the general chromite ore is slightly coarser, the monomer can be dissociated by simple rod mill grinding. At the same time, the rod mill has high output and product particle size. Uniform and adjustable, it is an ideal chromite grinding equipment.

Description. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
