Description

Technical Field

[0001] The invention relates to a residual anode multi-granularity crushing processing device, belonging to the technical field of aluminum electrolysis. Background Art

[0002] At present, the treatment method of anode scraps in most domestic aluminum smelters is relatively simple. After the surface of the anode scraps is cleaned, they are all put into the anode scrap pressing equipment. After pressing, they are sent to the warehouse for stacking and then directly shipped out for sale. At the same time, new anodes need to be purchased for production. This model causes a large waste of anodes. In addition, the stacking environment of the anode scrap carbon blocks is dusty and the working environment is harsh, which is not conducive to workers working for a long time.
