Abstract

1518940 Hammer mills HENRY BALFOUR & CO Ltd 22 Oct 1975 [25 Oct 1974] 46201/74 Heading B2A A multi-stage impact mill comprises a series of hammers 7A, 7B on a vertically-arranged shaft 6 each set of hammers being surrounded by a sieve 8, and by a discharge duct 8 A, 8A. Material introduced at 9 is thus discharged as a fine fraction via the first sieve 8 and duct 8A the courser material being discharged via the second sieve 8, and so on in sequence when more than two stages are used. The sieves may be blocked off where a simple pass grinding operation is contemplated and the bottom of the mill may be blocked off by a plate, not shown. Auxiliary feeder arms 21 encourage the downward flow of material to the hammers 7.
