Apparatus and method for circular vortex air flow material grinding |
摘要 |
A material grinding apparatus ( 10 ) includes an annular upper enclosure ( 12 ) defining an upper chamber ( 34 ) into which material to be ground is introduced from above, a conical lower enclosure ( 14 ) defining a lower chamber ( 36 ) and supported in tandem with the upper enclosure ( 12 ), and one or more angled slots ( 56 ) defined in the sidewall of the upper enclosure ( 12 ) through which compressed air is introduced relatively circumferentially into the upper chamber ( 34 ) so as to generate a circular vortex flow of air and material in the upper enclosure ( 12 ) for grinding and drying to take place. The air flow is exhausted by a pipe ( 92 ) through an upper end of the upper enclosure ( 12 ) and the dried ground material is discharged through an open lower end of the lower enclosure ( 14 ). The lower enclosure ( 14 ) is a downward continuation and extension of the upper enclosure ( 12 ) so as not to extend upwardly into nor past the upper chamber ( 34 ) thereof.
