Fe, Ni and Cr elemental powders have been ball milled in a planetary mill for various periods of time, up to 27 h. XRD analysis allowed the determination of the structure of the mixture, the average crystallite size and the lattice parameter as a function of milling time. The complete formation of FeNiCr is observed after 27 h milling.


Generally, the inner diameter of the hollow shaft is about 2 times of the larger ore feeding size, which is about 0.2-0.3 times of the inner diameter of the ball mill. The short length is for the higher speed of the flow of ore. Internal Structure Comparison. The internal structures of the ball mill, rod mill and SAG are different.


Tube Mill Internal. The tube mill internals of cement manufacturing industry is composed of the grinding media, shell liners and the diaphragm. The change in impact condition may result in either spalling or hardening of the grinding media which in turn decrease the shelf life, increase the operating cost and increase the downtime.

Corrosion of grinding media can affect its longevity (internal structure) and performance. This is generally the case in mills where chemicals, water with an acidic pH level or the ore's characteristics create a corrosive environment. A way to combat this is higher chromium content in the grinding media.
