Sizes	900mm to 3500mm
Drive Options	Electromechanical or Hydraulic
Capacity (mtph)	Up to 5000 mtph
Max Feed Size	Up to 1500mm
Options include:	Built in scrapper / Dribble blet

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.

SPECIFICATIONS

Duty	Primarily used under stockpiles (in tunnel) or under silos. Also feeding cone crushers at a constant rate
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

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

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	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

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.
