Study of Special Cements Based on Calcium and Barium Ferrites

Abstract

Pelletising, i.e. transformation of fine dusty materials into lump materials (pellets, briquettes, pellets), is an important technical task solved in many sectors of the national economy - ferrous and non-ferrous metallurgy, chemical industry and in a number of other industries. The process of pelletising ores and ore concentrates is of the greatest importance for the production of iron and steel, i.e. for ferrous metallurgy. The most common method of pelletising is pelletising - granulation of iron ore concentrates in special granulation plants, usually with the use of binders. As a result of pelletising, so-called pellets are produced, which are subjected to hardening firing (roasting pellets) or achieve the required level of properties without high-temperature treatment (non-roasting pellets) through the use of special binders. The current trend is the transition from firing methods of pellet hardening to non-firing (low-temperature) methods.
