Application of Ecologically Clean Technology to Drying of Iron-Ore Pellets

Abstract:

One of the advanced and unconventional forms of energy, i.e. super high frequency field energy, has been studied. Advantages of super high frequency field application have been demonstrated, in comparison with the other forms of energy. It has been found out, that the sources of super high frequency heating (SHF-heating) allow obtaining the concentrate free of combustion products, as well as reducing pollution of the environment. Drying of Olenegorsk fine grinding masterbatch (Olenegorsk Mining and Processing Plant) proves the value of these advantages and makes it feasible to adopt this process during preparation of the iron-ore pellets for metallurgical treatment. It has been shown that the intensity of drying in the SHF-field is vastly superior to the one achieved in conventional convection units, due to volumetric nature of the heating and more favourable conditions for heat-and mass-exchanging processes in the bed. The obtained results may be used for the development of the design of units for drying fine-grained materials in the SHF-fields.
