Outstanding Osborn Idlers win Platinum Award

Conveyor Idlers Booysendal platinum mine

A multi million Rand order for conveyor idlers for the new Booysendal platinum mine in Limpopo reflects the long-standing reputation for long life, low maintenance and minimum downtime of Osborn’s SABS-approved conveyor idlers.

Osborn conveyor products sales manager Donovan Baleta explains that it was the quality and competitive pricing of Osborn’s products that secured this order for idler bases, rolls and anti-run back rolls for Booysendal mine. “We are delighted to have this opportunity to work with long-standing customer DRA Mineral Projects, as well as Northam Platinum, which owns Booysendal mine,” he adds. Standard Osborn idlers have been supplied for this project, for conveyor belt sizes ranging from 900 mm to 1 500 mm.

Complete range of idlers

Osborn offers a complete range of standard and custom designed idlers, which have proven their worth to thousands of satisfied customers in underground, overland and in-plant conveying applications across various industries. The company's achievements in this area date back more than four decades, and include the installation during the 1960s and 1970s of conveyor systems at the Blinkpan and Usutu power station collieries, and Anglo American's rapid load out terminal near Witbank.

A stage-by-stage quality controlled manufacturing programme ensures that Osborn idlers and associated products are of the highest quality and provide customers with all the benefits they seek. The range of Osborn conveyor idlers enables customers to choose the models best suited to their needs.

Manufactured from steel and high-density polyethylene (HDPE), Osborn idlers are available in suspended, garland and standard designs. Deep-groove ball bearing or taper roller-bearing designs are available, and clients can choose from a selection of roll diameters (102 mm, 127 mm, 152mm, 165 mm and 178 mm) and roll shell thicknesses (from 3.8 mm – 6 mm).

High Impact Torsion (HIT) system

An outstanding and sought-after option supplied by Osborn for all conveyor systems – both new and existing installations – is the High Impact Torsion (HIT) system. Replacing impact beds and skid beds, this exceptional system is fitted under the chutes and in high impact areas, explains Baleta. It absorbs impact in these areas, and offers significant benefits, including longer belt life and longer idler life. “The impact is absorbed in the product’s torsion bar,” he explains. “There is therefore less impact on the belt, and the system reduces the likelihood of broken or bent frames.”

A noteworthy feature of the HIT system supplied by Osborn is that it can be fitted onto any new or existing installation. “No modification to the installation is necessary and the system uses standard SABS rollers,” Baleta stresses.

Renowned for ruggedness

With one of the largest manufacturing facilities in South Africa, Osborn offers commissioning, spares and after sales service on all idler products. The entire Osborn range of idlers is renowned for ruggedness, and represents years of design improvements and field experience gleaned from various installations around the world. Reflecting their quality, Osborn idlers boast ISO 9008 accreditation.

Crushers, feeders and screens

In addition to top quality idlers and associated products, Osborn’s equipment offering also includes an extended range of crushers, feeders and screens for the mining and quarrying industries.

Exceptional machines from Astec

Exceptional machines from United States-based Astec Underground, Trencor, Roadtec, BTI and American Augers are also supplied and supported in the South African market by Osborn, which is also part of the Astec stable and has become the African agent for its American sister companies. Machines like horizontal directional drills, auger borers, the Roadtec Shuttle Buggy and BTI (Breaker Technology Inc) hydraulic hammers are making their mark in the local market, and complement Osborn’s well-established equipment range.
