EV supply chain majors pilot Re|Source, a blockchain solution for end-to-end cobalt traceability

Metals and mining companies CMOC, Eurasian Resources Group (ERG) and Glencore in collaboration with battery material supplier Umicore are piloting ReISource, a solution to trace responsibly produced cobalt from the mine to the electric car. A global EV pioneer and one of the world’s leading battery makers are also part of the pilot. Tested in real operating conditions, from upstream cobalt production facilities in the Democratic Republic of the Congo (DRC) to downstream electric vehicle production sites, the pilot will run until the end of 2021, with the roll-out of the final solution expected in 2022.

QRC welcomes Submissions on Resources Industry Development Plan

The peak body for the resources sector in Queensland has welcomed the opening of submissions to the Queensland Resources Industry Development Plan (QRIDP) by the Queensland Government.

“The Queensland Resources Council (QRC) has been pleased to work closely with the Palaszczuk Government from the outset to develop the plan,” said QRC Chief Executive Ian Macfarlane.

“We congratulate Resources Minister Scott Stewart and his department on working with us to develop this important plan to ensure the resources sector and its communities remain strong and deliver jobs and prosperity for all Queenslanders,” he said.

Despite the COVID-19 pandemic, the resources industry has continued to ensure Queensland’s economic prosperity through its $82.6 billion contribution in the last year.

Training and Professional Tools extend Bearing Service Life


A manufacturer of polystyrene-based insulating products was experiencing frequent failures in the bearings of conveyors which link its machines. However, relatively easy control of the situation arrived following a hands-on NSK training course for maintenance personnel and the adoption of the correct bearing mounting tools.

To what extent does the correct mounting of bearings have an influence on their service life? In practice, this factor is often underestimated. The case of an insulation product manufacturer demonstrates that it makes sound economic sense to approach this maintenance task with the utmost professionalism.

Alongside other materials, the company processes large quantities of expanded polystyrene, with 3D parts milled from sheet material. The manufacturer transports the material by conveyor systems, with heavy exposure to abrasion and fine dust from the polystyrene. As a result, repeated failures were occurring in the rolling bearings of the conveyors.

Although the primary reason for the failures was the dusty and dirty operating environment, another cause was that maintenance personnel did not have proper training on how to handle the bearings and were using conventional, non-dedicated tools to perform the work.

Realising the need for correct training, the company asked NSK to deliver a practical course for its maintenance team. In a concise training session, maintenance technicians received instructions on how to mount and dismount bearings correctly and use professional mounting and dismounting tools.

Maintenance personnel are now aware, for example, that extreme cleanliness is essential in order to prevent contamination when mounting the bearings. Also, whenever bearing replacement takes place, there is a clear need to use dedicated NSK tools. The tools carefully apply the necessary forces so as to avoid any damage, never transmitting them across the rolling elements.

NSK’s tool set includes bearing extractors that are able to exert a strong pulling force without damaging adjacent components. To subsequently install the replacement bearing, tools are available that support efficient and damage-free cold mounting. For the manufacturer of insulating products, these tools are entirely adequate, since the bearings are relatively small and easily accessible, ultimately making it possible to dispense with hydraulic tools or induction heating devices.

Thanks to these measures, the company is enjoying lower labour costs as the time required PR Ref. S012021-N | 1/3 for dismounting and mounting failed bearings has reduced by a factor of 5.5. Furthermore, the service life of the newly installed bearings is significantly longer as there is no mechanical damage during cold mounting.

Only a small investment was necessary for the training, while the NSK mounting tool paid for itself within a few weeks.
