Research in the vortex installation drying, grinding and removal of chlorine-containing impurities from iron oxide

Purprose. Improving the quality of iron oxide by grinding it and removing chlorine-containing impurities. Development of the technological scheme for the decision of these questions with use of vortex devices and definition of optimum parameters of its work. The originality. The dependences of the degree of removal of chlorine-containing substances from iron oxide on the heat treatment temperature in the vortex apparatus are established. Practical implications. The main operating parameters of drying are determined, with these parameters will be active removal of harmful impurities of iron oxide concentrate, which will improve its quality and increase the range of products.
