Description

бы куски выдаваемого раздробленного скрапа имели fio длине грани 30-80 мм. Затем скрап в виде распределенного потока при незначительной ч еличине засыпки проводитс  черездва расположенных один за другим отделительных магнитных аппарата 3 барабанного THfiia Фракци  соединени  железа с алюминием выдел етс  из основного потока и с помощью Кбивейерных лент отводитс  в любом направлении.the pieces of crushed scrap to be delivered would have a fio face of 30-80 mm. Then, the scrap in the form of a distributed stream with an insignificant amount of backfill is carried out through two separated magnetic separation devices 3 of the drum THfiia.

Полученна  таким образом фракци  алюмини  непосредственно за этим на конвейере 4 пересекает контрольный участок 5. В случае наличи  остаточных включений железа фракци  ограниченно по времени мен ет направление и подводитс  либо к устройству б дл  классификации , либо к дробилке 2 дл  повторного измельчени . В случае классификации остаток на сите с размером  ч.еек 30-50 мм вновь подвергаетс  дроблению, а то, что прошло через сито, по конвейеру 7 вновь подводитс  к фракции алюмини .The aluminum fraction thus obtained immediately after this on the conveyor 4 crosses the control section 5. In the case of residual inclusions of iron, the fraction changes its direction for a limited time and is fed either to device b for classification or to crusher 2 for regrinding. In the case of classification, the residue on a sieve with a size of harnesses of 30-50 mm is again crushed, and that which has passed through the sieve is conveyed again to the aluminum fraction by conveyor 7.

Фракци  алюмини , котора  содержит не более 0,1% желейа в виде примесей или. включений, перед последующей обработкой путем расплава в печах по конвейерным лентам 8 и 9 направл етсй в бункеры 10. Отделенна  фракци  железа, сортируетс  вручную на сортировочном участке или посредCTBQM повторного магнитного отделени  с б.олее слабым возбуждением с помощью магнитного отделител  fI.Fraction of aluminum, which contains no more than 0.1% gel in the form of impurities or. inclusions, before further processing by melting in furnaces, by conveyor belts 8 and 9 are sent to bins 10. The separated iron fraction is sorted manually in the sorting area or through the CTBQM repeated magnetic separation with a weaker excitation using a magnetic separator fI.

Изобретение позвол ет удалить железо из фракции алюмини  до 0,1% и повысить экономичность способа.The invention allows iron to be removed from the aluminum fraction to 0.1% and to increase the efficiency of the process.
