BaFeO 4 was synthesized by solution reaction between Ba 2+ ion and FeO 4 2- ion. Li-doped BaFeO 4 was prepared by ball mill solid-state reaction between BaFeO 4 and LiOH. XRD spectroscopy and electrochemical methods were used to examine their structures and properties. The discharge capacity of barium ferrate was examined at room temperature.

Discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.

The size of the blind trommel and magnetic circuit can be varied to retrofit an existing ball mill and available space at the discharge. The magnetic circuit is designed to provide maximum strength for high slurry throughputs and up to 4 inch diameter grinding balls. The trunnion magnet can be configuration for reversing or bi-directional mills.

are grate discharge and ball mills are mostly overflow (a few, however, are grate discharge). In overflow mills the belly length inside liners, which is what the model requires to be input, is very close to the flange-to-flange length. In grate discharge mills it is the length as measured from the inside face of the

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to …
