The granulability and absorbtivity of sawdust and coke breeze were investigated.These properties are important within the preparation of agglomeration charge.They have a significant impact on plynodynamic batch conditions.Ability of materials to wet is a fundamental condition of granulability of materials.Wettability and water absorption of wood with liquids is generally significantly affected by their chemical structure.The important factors affecting the wetting process are undoubtedly the wood moisture content,the value of the surface tension of liquid media and their chemical composition.With increasing moisture content of wood,the time to equilibrium rises.Determination of water absorption and granulability of sawdust was conducted to seek their possible use as a partial replacement of coke dust in the production of the agglomerate.Experiments have been realized with alder,oak and pine sawdust and reference material-coke breeze.These materials were divided to four classes of granularity:supplied material,1-2 mm,0.5-1 mm and less than 0.5 mm.And different liquid media were used:water 16°C,water 60°C,soapy water,lime milk and surfactant. 展开更多
