“…Nowadays, it is practically impossible to find a production plant where the items or the materials do not undergo drying during their technological treatment [1][2][3][4][5][6]. Sometimes drying of certain materials is inseparable from their polymerization, and quite often these processes take place in one and the same unit.…”

“…The following kinds of drying are distinguished with regard to the method of power supply to the material to be dried: convection drying and conducted drying, as well as drying in energy fields, i.e. radiant heating drying, drying in a high-frequency flow, drying in the acoustic field [1][2][3][4][5][6][7][8].…”

“…Mechanism and kinetics of drying for the materials are detailed in papers [1,2,9,10]. Drying of the bed is the most important process of heat treatment of iron-ore pellets as it largely influences unit capacity and the quality of calcinated pellets [11,12].…”

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.
