Mining companies are under intense pressure to increase production through the optimisation of their current plant and its resources. In order to achieve this, it is important they preserve and extend their assets, a tactic with which Weir Minerals is very familiar.
“At Weir Minerals we recognise the demand within the industry and we have expanded our service offering as a result. We don’t just design and manufacture products; we provide tangible solutions for operators across the globe,” states John McNulty, Director of Technology for Weir Minerals.
When it comes to supplying solutions to mining operators, Weir Minerals ensure its personnel visit mine sites regularly to assess operators’ processes, discover their pain points and work with the customer to overcome productivity related problems, providing the solutions they need, when they need them.
This could be anything from modifying a cyclone cluster to developing a transportable self-priming pump to increase availability of a plant.
“It is our job to ensure operators maintain optimum performance of their plant, from comminution through to tailings disposals. We want to gain an understanding of their throughput issues and use our leading engineering expertise to deliver a comprehensive solution.”
Weir Minerals supplies tangible solutions to enable operators to use existing infrastructure and equipment to maximise production whilst minimising total ownership cost.
“It’s not about reinventing the wheel, it’s about re-thinking how we use current assets and working together to modify the process, increasing mine throughput and improving access to high-quality mineral resources.”
Through its plant optimisation strategy, Weir Minerals uses laser scanning technology to examine the entire plant, gaining a full understanding of all of the equipment, applications and processes present.
Many older plants no longer have access to their original drawings, or find that their original drawings are out-of-date due to modifications since the plant’s establishment. If original drawings are not available, or out-of-date, laser scanning is a useful alternative to create detailed drawings alongside 3D models.
This technology enables engineers to visualise where and how the equipment fits into the entire operation; identify what works and what doesn’t and detect bottlenecks.
Weir Minerals’ engineers can then refine the data collected to determine the best approach to modify and enhance the operator’s entire process.
“Laser scanning allows for us to modify our products to fit our customers’ application accordingly and enable them to run exactly how they need them to,” states McNulty.
It’s important to take a holistic approach to optimisation; modifying each process with the entire operation in mind, avoiding bottlenecks which slow down the overall process.
“A bottleneck represents a restriction in the process which must be dealt with to improve the production process. The key is to understand where the bottlenecks are in the process and evaluate the root cause before they negatively impact the throughput of the entire operation.”
Bottlenecks are inevitable in mining, therefore, it is important to unlock these barriers and plan the production flow accordingly.
Aside from removing bottlenecks, mine operators may be looking to expand capacity, lower operating costs, increase productivity; whatever the challenge, Weir Minerals is adept at providing innovative, multi-product solutions for customers.
McNulty concludes: “It’s our job to truly understand our customers’ challenges and use our engineering expertise to optimise the process, taking their business to the next level. We constantly look for innovative solutions to industry problems, and utilise our engineering skills, experience, entrepreneurship and innovation to address these problems.”
