Show r T r 7 you can keep down the dilution of your classifier overflow many flotation plants have obtained greater capacity and improved extraction by reducing the dilution of the feed to the cells this may be accomplished by using a dorr bowl classifier or by attaching bowls to the standard dorr classifiers already installed the use of the bowl classifier permits greatly increased overflow capacity as compared with that of the standard single stage unit thus overflow dilution may be kept at a minimum and a cleaner sand produced by means of the two stage classification dorr bowl classifiers can be adjusted to make any separation from 48 to mesh bowl classifier installations have been responsible for increased recoveries at many large flotation plants in this country they can probably effect similar savings in your plant it will pay you to investigate send for a copy of bulletin 2081 manufacturers of dorr agitators dorr washers dorr classifiers dorr slurry mixers dorr thickeners dorico pumps dorico filters dorico sand washers descriptive bulletins sent on request THE DORR COMPANY CHICAGO DE DENVER 11 VER I 1 1009 09 17 st sl ENGINEERS 3 10 S M A WT LOS A ANGELES G EL E S CITY T ll 8 W ast 5 PARK AVENUE NEW YORK la 13 Cd call 1 WILKES 36 miners dank bank bids bid TORONTO bay st sl 19 3 J all cle THE DORR COLTO CO LTD DORR Gm bH s 0 C WS DO RR c t 16 south 1 ld L london d e C i 2 10 belm W 15 jUip MENT investigation TESTS DESI DESIGN |
