Sova A. The improvement of production technology of agglomerate by forming rational cluster structure using separate preparation of charge and machining of cake

The goal of the work is the improvement of production technology of agglomerate in the current circumstances based on the results of researching of effective methods of separate preparation of charge constituents before sintering and methods of machining of cake in specially designed machines. It has been found, that preliminary separate pelletizing of composite out of concentrates - ore - lime - limestone with 0,9-1,0 units of basicity and residual charge with 1,6-1,8 of basicity together with further common granulation allows to form granules with necessary composition and size. It has positive impact on quality of sintered agglomerate. The studies in the regard of optimization of construction and technological parameters of drum type device, which provides effective machining of agglomerate were made. The using of proposed scheme of preparation of agglomerate that was stabilized by size and solidity will allow to decrease the content of trifle in it from 12 to 3-4% without significant increase in amount of fine fraction.
