METHOD AND PLANT FOR REWORKING ALUMINUM TINS

FIELD: production of aluminum lamella of different degree of dispersity.

SUBSTANCE: proposed method includes grinding, removal of iron inclusions and cleaning of organic admixtures. Grinding is performed at four stages: at first stage, particles of 15-25 mm in size are obtained; at second stage, particles of 3-8 mm in size are obtained and at third stage, particles not more than 1.5 mm in size are obtained; at these stages, grinding is performed in drum-type rotary grinders and fourth stage is performed in abrasion-type apparatus for at least 2 hours. Plant proposed for realization of this method, includes grinding unit and magnetic separator and is additionally provided with gas blower, classification unit and three rotary drum-type grinders mounted in series and abrasion apparatus. As a result, lamella of required sizes are obtained which are perfectly cleaned from organic inclusions.

EFFECT: enhanced efficiency. 6 cl, 1 dwg, 1 tbl, 1 ex
