Abstract
303,393. Newsom, J. F. Sept. 24, 1927. Upward-current classifiers. - In a classifier in which the material collects in a plurality of transverse rows of cells, each cell is supplied with an upward current and with transverse streams of water. The material is supplied from a rotary sieve 25 through an opening 27 to the classifier where it is divided into two portions by a baffle 29. Blades 20 on an endless chain move slowly in the direction of the flow of material which falls through guides 18 of varying inclination into the cells 1. Water is supplied to each row from a transverse channel 4 through openings 5 controlled by gates 6<a>, and flows upwardly through conical or fiat sieves 2. The gate 6<a> of each row is independently actuated. Radial streams of water are supplied through perforated vertical pipes 14 depending from headers 15. The cells have removable liners (not shown). The material passes into conduits 12 through openings 10, Fig. 11, which may have a cleaning device comprising a disc 37 having a passage 38 contracted at the centre. The disc is given a half-revolution to remove obstructions. The discs of a row of cells are mounted on a common shaft which may be mechanically actuated at regular intervals. The sieves 8 may be cleaned by scrapers 42, Fig. 9, resiliently mounted on a bar- 43 actuated by a cam 47 and springs 50, 51.
