     apron

    FEATURES

    Our Apron Feeders are built to take directly impacting rock in a range of sizes from 900 mm to 3500 mm wide to handle heavy, lumpy and abrasive materials, and provide a reliable means of controlling the feed rate to prevent surge loads to primary crushers, belt conveyors and other plant and equipment. Features include overlaping flights to limit spillage, Heavy duty frame with full length Beam top and bottom plus tied in cross members, Segmented bolt-on drive sprockets, dual key head-shaft, cast steel flights/pans, anti-friction spherical roller bearings, automatic greasing standard, Hydraulic chain tensioning, drop forged chain-links and full length impact rails.

     pan

    FEATURES

    The main feature of this feeder is the low power consumption, low noise and little maintenance required. Osborn Pan Feeders are generally installed at a 10 degree downslope to provide the best efficiency for the free flow of material. Fitted with replaceable liners and can be floor or suspension mounted. Pan Feeders are manufactured in many different widths and lengths from 300 mm wide up to a 2400 mm wide and up to 4000 mm long.

  • SPECIFICATIONS

    Duty Converts material flow into a low velocity to flow across width of machine

    Sizes

    300mm to 2400mm wide, up to 4600mm long

    Drive Options

    Twin Motor (OBEX), Double Shaft (Linear), Gearbox (GBEX)

    Capacity (mtph)

    Up to 3500 mtph

     
    Liners Available

    VRN-200, Ceramic, Rubber, Polyurethane, Poly-Hisolidur, Stainless 304 / 3CR12

     
     spreader

    FEATURES

    Designed to accept a fast material flow from a relatively narrow feed and convert this into a low velocity and uniform flow across the width of the machine. The Osborn spreader feeder is highly recommended for this.
    These feeders are capable of handling a wide range of products including materials such as damp clay and limestone and are ruggedly built for arduous trouble free service.

  • SPECIFICATIONS

    Duty

    Primary crushing sites, under surge piles. Operates via a push-pull action. These feeders generally work at a low frequency

    Sizes

    650 x 1000, 750 x 2400 & 1800 x 4600

    Drive Options

    Push-Pull via crank shaft connected to a fixed or variable speed drive

    Capacity (mtph)

    Up to 500 mtph

     
     reciprocating

    FEATURES

    The reciprocating plate feeder is generally installed at a primary crushing site and receives a positive feed of material from a bin or hopper. Its “push-pull” action is generated by a link arm that is connected to a crank shaft which is in turn connected to a variable or fixed speed drive unit . Plate feeders generally operate at low frequencies. The main advantages of a plate feeder over other feeding equipment:

    • Minimum damage from impact of large lumps due to cushion of material on the plates - With no carry-back of material, plate feeders operate with minimum spillage
    • Wedging damage is minimal
    • Low maintenance and operating costs
  • SPECIFICATIONS

    Duty

    The vibrating grizzly is used to separate ROM feed material into fractions prior to feeding the primary crushing stage of the process

    Sizes

    Length - Pan ~1m, Grizzly up to 5m Width 900mm to 3000mm

    Drive Options

    Vibrator Drive, Twin Shaft Drive, Linear Drive (twin/quad shaft), GBEX (Gearbox Drive)

    Capacity (mtph)

    Up to 2800 mtph

     
    Types Available

    1200mm (min) straight deck grizzly, optional stepdeck grizzly sections available

     vibratinggrizzly

    FEATURES

    Our vibrating grizzly are used in the harsest applications to separate ROM feed material into fractions prior to the primary crushing. The pan deck is typically 1 meter long whilst the grizzly bar section can be over 5 meters in length with varying widths from 900mm to 2400mm.

    The grizzly is generally installed horizontally but to improve material flow they can be installed up to a maximum 10 degree downslope. Grizzly bars can be arranged as a single, double or even triple row dependent upon the amount of scalping required. Capacities range from 250tph through to 2500tph. The vibrating grizzly can be used as a heavy duty high capacity, non accurate screen due to the grizzly bars being tapered to allow elongated particles to pass through. The Osborn grizzlies operate at a minimum of 4G’s force with an approximate amplitude of 10 mm.
