SPH Kundalila adds another Lokotrack LT120 for crushing fleet at platinum mine

SPH Kundalila has reaffirmed its faith in Metso Outotec crushers by putting to work another Lokotrack® LT120™ from local distributor Pilot Crushtec at an open-pit platinum mine near Rustenburg in South Africa’s North West province.

The Lokotrack LT120 mobile jaw crushing plant was acquired early in 2021, and has since been added to the fleet at the mine where SPH Kundalila has been conducting crushing operations for the customer since 2013.

“The new machine is part of our ongoing plant renewal process, ensuring that our fleet performs optimally with high uptime levels,” Graeme Campbell, Group Commercial Manager at SPH Kundalila, says. “We already have four of these models on other operations, and they have all been strong and reliable production units.”

The crushing fleet on this project processes 350,000-400,000 t/mth of platinum ore for the mine’s mineral processing plant. Material entering the crusher can be sized up to 800 mm in size, which is reduced to a product of 250 mm or less for transportation to the plant.

The mobility of the track-mounted LT120 provides the necessary flexibility that the mine requires to maintain a consistent grade for the plant, moving crushers when necessary to treat ore from different locations on site, according to the company.

SPH Kundalila Operations Manager, Dean Zeelie, says the Metso mobile crushers have proved themselves as reliable performers in front-line, hard-rock applications in the company’s contracts, with one unit notching up almost 25,000 hours to date.

“The Metso technology allows us to closely monitor machine running time and operating time, so that we can schedule regular service interventions,” he says. “Our on-site maintenance team ensures that all delivery targets are met, as our role in maintaining mine throughput is vital.”

This approach allows these mobile crushers to be completely refurbished at SPH Kundalila’s rebuild workshop in Potchefstroom at long-term intervals. This enhances reliability and lowers the total cost of ownership.

The close relationship between SPH Kundalila and Pilot Crushtec goes back over 23 years, according to Campbell, with the company investing in Metso crushers since 2007. He notes that they collaborate at early stages of potential contract opportunities when Pilot Crushtec will assist with testing and will then provide recommendations on the most suitable equipment for a job. He says Metso’s Bruno simulation software is also a valuable tool that the company uses for finding optimal solutions for its projects.

According to Francois Marais, Director Sales and Marketing at Pilot Crushtec, the Lokotrack LT120 includes a Metso C120 jaw crusher with a 1,200 mm by 870 mm feed opening, providing excellent capacity even in the toughest applications.

“The hydraulic drive ensures trouble-free operation and enables crusher direction to be changed in case of blockage or alternatively the on-board hydraulic hammer can be used, while the Caterpillar C13 engine module delivers optimal power to the high inertia flywheels,” Marais says.

“Its compact dimensions, combined with agile tracks, also make it easy to transport. The chassis design features good clearance at both ends, enabling simple loading on a trailer.”

Forte Demolition goes to work on chrome pelletising plant in Rustenburg

Forte Demolition Solutions, a subsidiary of surface materials handling expert SPH Kundalila, has started demolishing a chrome pelletising plant in Rustenburg, South Africa, following a recent turnkey contract award.

Forte says it is tackling the project with its specialised range of mechanical dismantling and demolition equipment.

Graeme Campbell, Group Commercial Operations Manager at SPH Kundalila, said: “Our investment in this equipment is substantial, making us the ideal partner for mines and other operations who need to address closure in a safe and sustainable manner.”

The plant to be demolished includes several multi-storey structures, conveyors, steel frames and concrete work, as well as large, heavy componentry, according to the company.

Campbell emphasised that Forte Demolition is one of few companies in South Africa with the necessary assortment of fit-for-purpose machinery and attachments. These ensure the cutting and breaking process is safe and efficient, allowing many components to be carefully dismantled for resale purposes.

“Among the factors behind our cost effectiveness is that we can shorten customers’ timeframes,” he said. “For example, our precision cutting is done by a shear attachment on an excavator. The power of hydraulics – combined with our specialised technology – means that everything is much quicker and safer.”

Equipment that is being employed on the pelletiser site includes a pulveriser for concrete demolition. It breaks concrete into small pieces that can be used as backfill on site, alleviating the need for transporting large concrete chunks to special dumping sites. Other specialised demolition attachments include grapples, hammers and buckets.

High levels of safety are ensured by an integrated safety, health, environment and quality management system, according to Brad van Niekerk, Project Manager at Forte Demolition Solutions.

“Safety is our key priority, which is enhanced by the closely supervised use of our mechanical equipment,” van Niekerk says. “This ensures that workers are not placed at risk by being too close to dangerous working environments.”

He notes that each project is planned and monitored by a skilled professional team, which takes the safest demolition approach. This is also aligned with customer standards to ensure full compliance with corporate and regulatory requirements. A 51% black-owned business and Level 2 B-BBEE contributor, Forte Demolition Solutions operates in South Africa through its offices in Fochville, Rustenburg, Stilfontein and Carletonville.

Anglo American’s OiS improving employee safety at Rustenburg base metal refinery

Anglo American’s real-time data analytics platform, Operational Intelligence Suite (OiS), is helping its platinum subsidiary tackle potential health hazards at the Rustenburg base metals refinery in South Africa.

The company’s Occupational Health and Information Management teams worked in partnership to develop OiS, which is able to interrogate data feeds, manual uploads and events, Anglo said.

“The diagnostic results generated by the platform helps users make the right decision, at speed, when things go wrong, in terms of performance and health and safety at our mine sites.”

The information can then be used to do a “deep dive” analysis, to get to the root cause of problems and prevent repeat occurrences.

Cas Badenhorst, Anglo’s Occupational Health and Hygiene lead, said the company developed the product in response to a growing need in the business.

“Some of our key stakeholders needed a tool that would allow them to evaluate workplace and external environments and impacts on communities as well as monitor control performance,” he said.

The key difference between Anglo’s OiS system and other, off-the-shelf, products is its ability to receive, record, and analyse data such as air flow, gas levels etc. from multiple sources on to a single platform that also has analytical and reporting capabilities, Anglo said.

OiS is already in place at several of Anglo’s businesses including subsidiary Anglo American Platinum, where potential exposure to health hazards is being reduced by real-time monitoring of dust, noise, and gases.

“In fact, application of the OiS platform has assisted the Rustenburg base metals refinery (RBMR) team to achieve significant reductions in personal exposures to airborne pollutants within 12 months by optimising control measures,” Anglo said.

When asked about the value contribution of the OiS platform, RBMR General Manager Fortune Mashimbye said: “OiS informs me daily of health-related control performance and supplies me with data and information, so I can act on substandard conditions. Having access to real-time information on workplace conditions and control status empowers me and my team to actively protect the health of the RBMR employees.”

The system is currently being introduced at Anglo’s Kumba Iron Ore business, its Coal South Africa company and Copper division’s Chagres site in Chile. Further roll-outs are planned for Brazil and Botswana in 2019, the company said.

“The next phase of development will include predictive analysis that could, potentially, prevent control failures and health and safety incidents from happening,” Anglo said.

The system was recognised at the 2018 USA National Institute for Occupational Safety and Health (NIOSH) Awards, where it took the award for Technology Innovation in Health and Safety.
