FIELD: metallurgy industry; methods of preconditioning of the iron-ore charge for the agglomeration. ^ SUBSTANCE: the invention is pertaining to the field of preconditioning of the ground iron-ore raw for the agglomeration by the method of pelletization, agglomeration or briquetting. The ferromagnetic and non-ferromagnetic components are sequentially batched on the common transportation device with the simultaneous treatment of the ferromagnetic component with the magnetic field, admixed and fed the averaged charge into the agglomerating device. Feeding of each non-ferromagnetic component in the layer of the transported ferromagnetic material carry out in the working area, which is open heteropolar variable-polarity in the direction of the ferromagnetic material movement of the multipolar magnet system with induction of the magnetic field from 0.1 up to 0.3 T. On the section of batching of the non-ferromagnetic component into the layer of the transported ferromagnetic material the latter is simultaneously subjected to the vibrational impact. Further the charge is transported along the poles of the alternating polarity located inside the rotating drums-rollers of open magnetic systems. The invention allows to increase the quality, efficiency and homogenization of the averaging of the charge. ^ EFFECT: the invention ensures the increased quality, efficiency and homogenization of the averaging of the charge. ^ 1 dwg, 1 ex |
