Conveyor pulleys serve as the driving force of conveyor belts, a critical component in the conveying process.
Kinder Australia’s 40-year history of serving the Victorian Earth Resources industry has allowed us to develop a deep understanding of the unique challenges faced by those involved in construction material processing.
Kinder’s dedicated engineering team delivers exceptional value to customers by offering K-Conveyor Pulleys, specifically chosen to suit each unique application, whether it be hard rock, gravel, sand, masonry, clay, lime, soil, gypsum, or recycling.
The Selection & Design Process
If the pulley is chosen haphazardly, damage to the conveyor belt and misalignment could potentially occur. It is risky to use a one-size-fits-all approach as there is an increased chance of unscheduled downtime, or worse, a dangerous failure.
Kinder uses classical stress calculations via our proprietary software to determine the stresses, deflections, factors, and formulae for pulley design. Minimising stresses at critical locations around the pulley, such as the welded shellend disc connection, is important to prevent fatigue cracking.
Each pulley undergoes 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.
K-Conveyor Pulley shafts from Kinder are designed to comply with AS1403. Kinder’s primary goal is to ensure the shaft has an infinite fatigue life under the expected operating loads, achieved by incorporating a suitable safety factor. To ensure quality and strength, shafts are ultrasonic tested after machining where required.
Kinder’s K-Conveyor Pulleys are designed and manufactured for maximum service life and fit-for-purpose applications. Manufactured against customer specifications or using the latest software to ensure infinite equipment life.
Lagging Options
Conveyor lagging provides a protective layer that shields the pulley from wear and tear caused by the belt and materials it carries. Lagging also improves traction between the pulley and belt, preventing slippage and ensuring efficient operation.
Kinder provides a range of high-quality, durable lagging materials, each tailored to suit specific environments and conveyor applications:
- Rubber Lagging
- Polyurethane Lagging
- Ceramic Lagging
- Slide Lagging – Talk to Kinder to discuss the best lagging option for your application.
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 may be inadequate for the duty.
K-Conveyor Pulley Projects
The success of your conveyor system hinges on the informed selection of the right pulley, not a cookie-cutter approach.
For 40 years, Kinder has been a leader in the Victorian Earth Resources industry, supported by teams of Field Application Engineers, Specialists, and a dedicated Engineering Department.
Kinder’s expert team brings their knowledge and a wealth of precision tools to the table, ensuring you get the correct pulley for your exact application.
