我厂直接还原车间所生产的金属化球团中,由于工艺本身的原因,混有一定数量的煤、煤矸石、煤灰、石灰等非磁性杂质。原流程设计中曾采用一台8A925型磁滑轮,将产品分选为成品球和废弃杂质两部分。但因金属化球含金属铁较高,磁性极强,加之有一定比例的粉状磁性物(粉化的金属球),磁分离效果极不理想。为此,该车间将电磁滚筒加以改装(附图),用一根短皮带悬空装在产品运输皮带头部,同向运行。当物料经电磁滚筒下边通过时,磁性物料被电磁滚筒吸引,由短皮带头部排出;非磁性物料由运输皮带头部排出,调整两条皮带的间距和磁
In the metallized pellets produced by our factory, we can mix a certain amount of non-magnetic impurities such as coal, gangue, coal ash, lime and so on due to the process itself. The original process design used a 8A925-type magnetic pulley, the product is sorted into finished balls and waste impurities in two parts. However, due to the higher metal ball metal iron, magnetic extremely strong, combined with a certain percentage of powdered magnetic material (powdered metal ball), the magnetic separation is very unsatisfactory. To this end, the workshop to be modified electromagnetic drum (with photos), with a short belt hanging in the product transport belt head, the same run. When the material passes under the electromagnetic drum, the magnetic material is attracted by the electromagnetic drum and is discharged by the head of the short belt. The non-magnetic material is discharged from the head of the transport belt to adjust the distance between the two belts and the magnetic
