Osborn Telsmith SBS Gyrasphere Cone Crusher

Written by

Osborn Telsmith SBS Gyrasphere Cone Crusher

The SBS Gyrasphere Cone Crusher is designed with a taper head for producing a more cubic product, and crushing stone at an increased capacity. Features are:

  • Hydraulic clamping and relief system to protect from crushing chamber overload
  • Hydraulic locking of the upper frame / concave support bowl / locknut threads to prevent movement during crushing
  • Hydraulic power rotate to provide rapid adjust and unscrew features
  • Proven Telsmith combined cam and lever advantage for a powerful crushing action
  • Fabricated counterbalanced rotary seal ring offers greater machine balance, resulting in smooth operation, while the non-contact seals reduce costly maintenance and minimize wear
  • To prevent dirt and dust from entering the crusher lubrication system, the manganese mantle can be replaced without removing the head and shaft assembly
  • For control and safety, the crusher boasts a safety shut-down system
  • Incorrect oil temperature, flow or pressure activates an alarm and stops the crusher
  • Anti spin device option.
  • Thrust roller bearings.

Telsmith Gyrasphere Cone Crusher

For productivity and reliability, the Telsmith Gyrasphere Cone Crusher offers unbeatable value. The machine offers great structural strength, the use of improved alloys and heavy components.

  • Heavy, fast acting springs offer positive protection against tramp iron.
  • Long throw spherical head action easily handles large and slabby feed, prevents bridging and keeps capacity at its maximum.
  • To produce a powerful crushing action, the Telsmith Gyrasphere uses the combined force of a cam and lever action.
  • To reduce stress to an absolute minimum, the power of the two forces distributes the loads evenly over a large bearing area.
  • The counterbalanced rotary seal ring offers greater machine balance, resulting in smooth operation, while the non-contact seals reduce costly maintenance and minimize wear.
  • Locking of the concave support bowl is by positive action Belville washers, when using hydraulic unlock cylinders alternatively by wedges.
  • Incorrect oil temperature and pressure activates an alarm and stops the crusher.

Toothed Roll Crusher for Cobalt Plate

Written by

Designed by Osborn South Africa, this machine is designed specifically for processing cobalt plate. It is used for 4mm thick plate, and works at a feed rate of more than 5 tons per hour.

The two non-adjustable rolls are supported on heavy duty bearings to withstand shock. The rolls are cast in high quality steel with hardfaced tips to extend life. The rolls are machined internally and machine fitted onto the keyed centre barrel.

The rolls are easily replaced by undoing the retaining bolts on either side of the crushing segment and sliding off the centre barrel. The teeth on either roll are timed to mesh perfectly to produce a product of 20 x 20mm which crushing 4mm thick cobalt plate. The rolls rotate at 10rpm.

Rolls are connected via heavy duty straight cut gears to ensure timing of the toothed segments. A simple grease lubrication point is provided.

A heavy-duty Flender gearbox with 22kW flange mounted motor is used for 4mm thick feed size. For thicker plates this may change.Material is fed into the Crusher by hand via the built-in inlet chute. This ensures that material is presented to the rolls at the correct angle and feed rate. Inlet width is 900mm. Roll size is 380mm diameter by 940mm diameter

Jaw Crushers

Written by

Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw. The swing jaw being the moving part is attached to a rotating eccentric shaft. The fixed jaw is an integral part of the crusher frame. Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn. During the crushing operation, the toggle plate which acts as a pivot point for the jawstock, controls movement of the lower part of the swing jaw.

 

Osborn Hadfields Jaw Crusher (Single Toggle)

The single toggle crusher is designed for a high capacity throughput due to the elliptical movement of the swing jaw which also assists in the discharge of the crushed material. As the single toggle crusher will achieve far higher capacities than the double toggle design, they are often used as a primary crusher.

Features:

Production capacity up to 1,600 t/h
Rock compressive strength up to 400 MPa
Excellent nip angle
Fabricated main frame and swing jaw
Reversible jaw dies for maximum wear
Relief / adjustment

Osborn Hadfields Jaw Crusher - single toggle

 

Osborn Hadfields Jaw Crusher (Double Toggle)

For much harder and highly abrasive materials with a compressive strength of up to 600 Mpa, the double toggle crusher would be the preferred machine.

The double toggle is capable of handling extremely hard rock and Ferro materials, but rate of feed and reduction ratio’s are restricted. With the top of the hinged swing jaw almost perpendicular to the crushing chamber, high compression is achieved by the linear stroke of the toggle movement thus minimising wear on the jaw liners.

Features:

Production capacity up to 600 t/h
Rock compressive strength up to 600 MPa
Excellent nip angle
Fabricated main frame and swing jaw
Reversible jaw dies for maximum wear

Osborn Hadfileds Jaw Crusher - doubgle toggle

 

Osborn Telsmith Jaw Crusher (SA)

Features:

Production capacity up to 1,000 t/h
Rock compressive strength up to 500 MPa
Patented hydraulic beam locking system
Excellent nip angle
Fabricated main frame and swing jaw
Reversible jaw dies for maximum wear
Relief / adjustment
