Vibrating Screens

Osborn has probably the largest range of vibrating screens available in South Africa. These include the Telsmith, JCI-KPI and in-house Osborn brands. The range extends to twin motor out-of-balance exciters to standard eccentric mechanical shafts or heavy-duty gearbox exciter types. Osborn designs offer unique screening solutions for extreme screening applications. Models include the SuperKing Screen, the Osborn Linear Dewatering Screen, the Osborn Exciter Driven Screens and the Osborn Obex Screens.


Exciter Driven Vibrating Screen

Osborn Exciter Driven Screens use finite element analysis to provide optimum performance and structural strength. The Exciter Driven Screens are locally built in our Elandsfontein works providing quality workmanship.

The Exciter Driven Unit is designed to handle high amplitude vibrations without decreasing life expectancy.


KPI-JCI Mobile Screens

KPI-JCI and Astec Mobile Screens engineer the toughest, most versatile, most efficient screens available.

High-frequency screens

Astec Mobile Screens’ high-frequency screens are engineered to provide higher production capacities and more efficient sizing compared to conventional screens. High-frequency screens feature aggressive vibration applied directly to the screen that allows for the highest capacity in the market for removal of fine material, as well as chip sizing, dry-manufactured sand and more.


  • Large-capacity hoppers make big jobs easy to handle.
  • Hydraulic screen angle adjustment reduces downtime by making adjustments quick and easy.
  • Easy-to-reach engine controls and grease points allow routine service to be conducted efficiently.


Multi-frequency screens

High frequency for sorting small diameter material and high amplitude for screening larger aggregate, the Multi-Frequency Screen can handle any job you throw at it - without sacrificing an ounce of performance or a penny of profit.

With the combination of both conventional and high-frequency screen movements integrated, the screen is able to maintain the higher production rates of a PEP screen, at a lower angle, while handling higher moisture content materials.  Coarser material requires more amplitude and less frequency, while finer material requires less amplitude and more frequency.

When these two theories are combined, it provides a versatile screen that is easy to apply in a variety of applications. By working at a lower operating angle, the overall height of the machine is less—making the machine safer to work on and operate.  With high-frequency and high-amplitude vibration, there’s no job this screen can’t handle.


  • Better performance than a conventional incline
  • Lower Operating angle than a High-Frequency Screen
  • Rotary Tension design allows quick screen cloth changes
  • Screen cloth won't blind
  • Versatile for almost any application
  • High-frequency and high-amplitude
  • Superior performance

Osborn Linear Screen

Osborn Linear Screens are designed in Austria utilizing finite element analysis to provide optimum performance and structural strength. The Osborn Linear Screens are locally built in our Elandsfontein works ensuring quality workmanship, excellent support and good delivery times. The Unit is designed to handle high amplitude vibrations without decreasing life expectancy.


Osborn Obex Screen

Osborn Obex Screens are locally designed and built to meet the needs of Southern African mining and quarrying operating conditions. The extensive range of vibrating feeders have been tested and proven in ongoing programs of intensive field research, through years of use in mines and industry throughout Southern Africa.

Two vibrating motors rotate in opposite directions, synchronise and impart a vibrating force in a longitudinal direction. This lifts the material and carries it forward on each rotation, providing a constant feed rate. The amplitude can be varied by adjusting the out-of-balance weights on the vibrating motors to the required stroke.

The frequency depends on the use of 4-pole and 6-pole motors, as dictated by the applications.



SuperKing Incline Screens

The Osborn Telsmith Superking range of heavy duty inclined screens have set the standard on most primary screening and scalping applications through exceptional reliability and high productivity in the toughest industrial environments. Adjustable counterweights ensure optimal stroke for each application. The patented counterweights also help the Superking screen to keep its composure during start-ups and shutdowns.

Osborn Telsmith Superking Screens are capable of a wide variety of applications from heavy duty scalping behind large primary crushers to final sizing down to 4 mm.

With one of the largest and most modern facilities in South Africa, Osborn also offers installation, commissioning, spares, reconditioning and after sales service, plus the capability to supply the right unit for any type of inquiry.
