BMG’s KZN field service team plays an important role in the sugar industry

BMG’s KZN field service team plays an important role in the sugar industry during off crop seasons and with urgent breakdowns in sugar mills and refineries

BMG’s KZN field service team has been involved in a number of field service projects in the local sugar industry during recent off crop seasons, as well as dealing with urgent breakdowns in sugar mills and refineries.

A recent field service project completed during the previous off crop season was a turnkey in-situ replacement of diffuser head shaft bearings and the complete refurbishment of the multi misalignment couplings driving each end of the head shaft.

“BMG’s design and installation team faced many challenges during this project, including the lack of engineering drawings required for the manufacture of replacement components. This meant bearing sleeves could only be final machined after the extraction of components, some of which had been in operation for approximately 20 years,” says Chris Johns, regional manager, KZN and Swaziland, BMG. “Restricted space for moving enormous components, added to the difficulties of the project. Due to extended reach of the head shaft, it was not feasible to use the conventional approach of using mobile cranes. Instead, support structures were specially manufactured and placed under the 126 ton head shaft and used to jack the shaft up and out of the pedestals, allowing the team access to replace the 900 mm bore diameter bearings.”

“BMG coped with extremely tight timeframes to manufacture replacement components and complete project, which also involved the installation of new bearings and adaptor sleeves, as well as new keys and connector arms for the couplings.”

BMG’s field service team has recently attended to a failure on a mill gearbox in KZN, where the coupling box had seized, causing excessive axial loading on the final drive bearings, resulting in failure of these bearings.

The complete mill gearbox had to be dismantled, all gearing dressed and damaged components repaired. Scope of operations also included fitting and mounting of all bearings, re-assembly of the gearbox and alignment and blueing of all gearing. BMG supplied new bearings, adaptor and withdrawal sleeves, seals and grease for this project.

Recent breakdowns in the sugar industry involved attending to a Dorstener mill gearbox in Swaziland and a shredder failure in KZN.

BMG is committed to providing engineering solutions and technical services that optimise productivity, to make a difference to the efficiencies of every sugar mill and refinery.

A wide range of products, selected especially for the sugar industry, is available from BMG, throughout Africa. These components include carrier and diffuser chain, knife and shredder bearing housings, custom sprockets and gear couplings, as well as steam gaskets, heat exchangers and hydraulic tools. Diffuser and mill gear boxes, in addition to mill lubrication and hydraulic systems, form a critical part of this range.

BMG’s specialist services to the sugar sector include bearing and gearbox inspection, bearing and chain refurbishment, large size bearing assembly and alignment and balancing, as well as customised product design. BMG also offers a trouble shooting and maintenance service, condition monitoring and training.
