Implementing accurate load monitoring systems can save mines and quarries significantly by identifying and reducing “black belt” time when the plant is running but not producing anything, according to Soeren Schramm, product manager for Loadrite.

Australian mines, quarries missing out on potential profits

Australian quarries are missing out on potential profits by not taking advantage of technology to maximise production, according to Soeren Schramm, product manager for Loadrite.
Loadrite load weighing technology and payload information systems are installed on wheel loaders, excavators, conveyor belts and other equipment to ensure optimal loads and provide quality data for productivity analysis.

A May 2012 report from IBISWorld – Gravel and Sand Quarrying in Australia – projected that the industry would achieve revenue of $1.05 billion in 2011-12. The outlook is cautiously optimistic, with the volatile market conditions of the past five years to continue in the medium term. Short term increases in construction activity will create demand for sand and gravel, however, making now the ideal time for mines and quarries to find ways to capture lost revenue.

Schramm says international organisations have already embraced the concept of maximising productivity and minimising costs, with the US industry achieving profits of 30 per cent of total revenue. In contrast, the Australian quarrying industry achieves profits of 26.5 per cent of total revenue – a figure that could be significantly improved by fully adopting available technologies, according to Schramm.

“The key productivity driver is moving more material through the plant in less time,” Schramm said. “But you can’t change what you can’t measure, so the first step must be to introduce an accurate system that allows you to identify where efficiency gains can be made.”

“When business is good, the focus is on delivering large volumes with less consideration of the cost of production,” said Bruce Warner, the Australasian region manager for Actronic Technologies, the manufacturer of Loadrite.

“Many smaller quarries cannot justify the cost of a full featured plant automation and reporting system. Some quarries are collecting performance information on remote operations but the data collection process is highly labour-intensive and often error-prone.”

With recent news that two of the country’s largest resources companies are cutting staff, Schramm says mine and quarry operators need to do everything they can to manage costs and boost productivity.

“The crushing and screening process is one area where significant efficiency gains can be made,” he said. “Ideally, the plant should produce to a certain level at all times but, in reality, most plants have ‘black belt’ time when the plant is running but not producing anything. This black belt time is essentially lost money – so being able to identify it and address it is crucial.

“Companies need to be able to see where the bottlenecks and pinch points are in their processes. They also need to be able to track tonnes per hour through their plant, track inventory and even assess the wear rate of parts. Doing all this and keeping tabs on black belt time can help operators make adjustments that can really impact their bottom line.”

The Loadrite C1850 conveyor belt weighing system and Insight reporting system together are a highly cost-effective option that
allows mine and quarry operators to monitor production at a fraction of the cost of other systems.

“The C1850 ensures accurate weighing for fixed plants as well as mobile crushers, screens and stackers, while the Insight software is a revolutionary new web-based system that offers the reporting power of the alternative, very expensive PLC/SCADA systems at a much lower cost,” Schramm said.

The C1850 and Insight can be configured for direct delivery of reports to email using cellular modems, weighing with chain idlers and user-defined, tailored reporting.

They have been installed in various operations around the world, delivering substantial productivity increases.

“Australian operations need to be looking for these kinds of efficiencies to maintain profitability,” Schramm said.
