The present invention has advantages below compared with prior art:
1st, the present invention applies to Kaldo Furnace in the processing of electricity/wiring board, reclaims out high-quality copper by oxidation, blowing, removes
Also the noble metal gold, silver in electricity/wiring board, palladium, iron can effectively be reclaimed outside this.
2nd, because the main raw material(s) of electricity/wiring board is that particle is more bulk after resin and glass fibre, crushing, area is larger,
It is unfavorable for the direct continuous charging of the modes such as charge pipe.If selection interval feeds, the production energy of Kaldo Furnace is greatly reduced again
Power.Therefore, the screw feeder mode in the present invention can effectively solve problem above.
3rd, the feeding device in the present invention so that the particle charging after electricity/wiring board is crushed is carried out continuously, and is effectively increased
The bed ability of Kaldo Furnace so that METAL EXTRACTION is more abundant in electricity/wiring board, advantageously in purification of metals, enrichment.
