After some other processes, αFe 2 O 3 red powder particles byproduct of regeneration of spent pickling liquor in ARP in iron and steel industry should be ground up to pigment grade to convert it to a value added product, red iron oxide pigment. In this study, grinding tests on αFe 2 O 3 red powder were performed using four different types of laboratoryscale mills, namely the vibrating ...
in AirJet Milling The grindng in the airjet mills is called jetting. This consists of pulverization caused by the collision of parts of solid bodies carried by the gas jet decompressed in the nozzles [7, 81, Illustration 1 presents a simplifie'd schema of the pulverization process in the airjet mill's grinding chamber. Thematerial for grinding
