“Custom pulleys are a large part of the industry.  A one-size-fits-all approach can potentially result in unscheduled downtime or worse, a dangerous failure”, says Cameron Portelli, Senior Mechanical Engineer.

Kinder has developed its own software that is constantly being built upon and informed by the Australian Standards.  When it comes to pulleys, the business uses AS1403 to determine the factors and formulae to inform the pulley design.

Kinder Engineers are leaders in the use of finite element analysis, along with classical stress calculations to determine the stresses and deflections in conveyor pulley shells.

Minimising stresses at critical locations around the pulley, such as the welded shell-end disc connection, is important to prevent fatigue cracking.

Each pulley undergoes static and dynamic balancing, with the welds fully stress-relieved and crack-tested with magnetic particle inspection and ultrasonic testing to ensure they will stand up to the pressures of their environments. Shafts are also ultrasonic tested after machining where required.

Portelli said the company’s engineers have a deep understanding of AS1403, which allows them to drill down into it and optimise the designs.

Kinder’s K-Conveyor Pulleys are designed and manufactured for maximum service life and fit for purpose application.  Manufactured against customer specification or using the latest software to ensure infinite equipment life.  Shafts are designed to comply with AS1403.

Standard / Optional Features:

  • Machined or Cast end-discs.
  • Full Penetration Welds to the end disc.
  • Static and/or dynamic balancing to application or customer requirements.
  • Shaft Material K1045 or 4140.
  • Key-less connection of shaft to end-disc, selected to transmit the design torque and resist the shaft bending moment.
  • Shells made of rolled steel-plate or pipe.
  • Pulley shell surfaces available in plain steel, vulcanised rubber (120° diamond shaped pattern) or ceramic tiles.
  • FRAS, Polyurethane and Slide Lagging also available.
  • Crowned or flat face options available.
  • Stainless Steel options available for corrosive or magnetic applications.
  • Welds fully stress relieved and crack tested via Magnetic Particle inspection and Ultrasonic Testing

K-Conveyor Spiral, Wing and HD Wing Pulleys

These specialised pulleys are made for difficult applications where material build-up occurs on the pulley face causing mistracking and belt damage.  Fugitive material is ejected to either side of the pulley via the centre tapered cone.

K-Conveyor Spiral Pulleys are designed to be used for dry and free- flowing materials.  The rotation of the pulley engages the self-cleaning action therefore releasing foreign material through and on to the inner tapered cone then to the outside of the conveyor.

K-Conveyor Wing Pulleys can be used for large lump, sharp and sticky materials and are designed to be used in adverse, very abrasive and dirty applications, especially where there is material build-up on a solid conveyor pulley shell.

K-Conveyor HD Wing Pulleys are designed for applications where the standard wing design maybe inadequate for the duty.
