Method of feeding sintering material by use of magnetic forces

A method of the magnetic loading of a sintering material wherein a starting sintering material is cut out of an ore supplying hopper by means of a drum feeder and is then charged onto a pallet mounted on a sintering apparatus of a Dwight-Lloyd type to hereby bring the starting sintering material into layered form on the pallet, the method comprising:

• applying a magnetic force to said starting sintering material having been cut through the drum feeder and being continuously flowed as said starting sintering material slidably dropped out of a tip of a sloping chute of a plate type onto the pallet, the magnetic force being generated by a cylindrical magnetic drum located downwardly of the sloping chute;
• an ancillary sloping chute is located beneath the plate-type sloping chute normally disposed and in parallel spaced relation to the latter, the normal sloping chute being reciprocative between a position in which it is operative and an upwardly slant position in which it is retractive, the magnetic drum located downwardly of the normal sloping chute is horizontally reciprocative forward and backward, and the starting sintering material is adjusted such that the path of dropping from the ancillary sloping chute to the magnetic drum is prevented from becoming varied through horizontal reciprocation of the magnetic drum located downwardly of and correspondingly to the ancillary sloping chute during displacement of the normal sloping chute from its operative position to its upward retractive position so as to remove part of the starting sintering material having attached thereto;
• and causing magnetically susceptible sinterable substances present in said starting sintering material to be magnetically attracted toward and attached to a lower portion of the sintering material layer, while segregating particulate substances of low drop speed present in said starting sintering material in that lower portion, whereby both said magnetically susceptible sinterable substances and said particulate substances of low drop speed are segregated in large amounts in an upper portion of the sintering material layer on the pallet by inverting said starting sintering material when it is loaded on the pallet with use of the magnetic drum.
