Metso adds crushing & screening flexibility to the process flowsheet with My Plant Planner

Metso is looking to increase access to and improve the visualisation of mining process flowsheets with a new tool that could ultimately see more of its equipment end up at mine sites.

My Plant Planner offers engineering customers and mining end users the ability to model a flowsheet after inputting certain key parameters of their orebodies. They can then also visualise this plant layout in a platform that is free to use.

Metso, along with other OEMs, has provided visualisation tools to the industry for many years.

The company’s Bruno simulation software has over 7,000 users and has been helping customers select the right equipment for their mines since 1994. This software includes all the necessary Metso equipment, such as feeders, crushers and screens, and shows outputs for different end products, providing users with the data they need to make informed decisions on the right equipment.

My Plant Planner utilises this simulation expertise, but does so at a much earlier stage of the equipment selection process.

With the tool, customers can pick and choose different types of crushers, screens and conveyors to get the perfect balance for the circuit and identify bottlenecks to understand where extra capacity is needed, according to Metso.

Important factors, such as capacity, load, and power draw, are updated in real time as the circuit is designed and the parameters updated. At any point, it is possible to download a report that gathers together all the details about the plant being designed. It includes details on the chosen crushers, screens, conveyors and their parameters, including power consumption.

“We decided to develop this tool as we were seeing different types of requirements from our customers and EPCMs (engineering procurement and construction management) at the time around prefeasibility studies and we wanted to be more reactive to this,” Guillaume Lambert, Vice President of Metso’s Crushing Systems business line, explained to IM.

Prior to using such a tool, these EPCM firms were developing flowsheets for economic studies – the type of documents investors use to gauge the potential profitability of a mine development – over a matter of months or years in tandem with OEMs, before moving onto obtaining quotes based on their mining customers’ budgets.

As time has gone on, these firms have been asked by their mining customers to factor in more requirements into these studies. One may require a reduced plant footprint due to the proximity of indigenous communities; another may request that energy consumption is reduced in line with existing available power infrastructure in the region.

The requests vary depending on the size of company, the location of the project, the commodity and many other elements.

This is where the three-dimensional aspect of My Plant Planner is very important, according to Lambert, providing customers with not only a visualisation of the flowsheet, but also a gauge of the physical constraints that cannot be represented in 2D form.

This means companies assessing brownfield assessments can factor in height and width restrictions of existing infrastructure against capital expenditure requirements.

The turnaround time for the type of analysis being carried out by My Plant Planner is also a key selling point, allowing companies to generate results in a matter of hours, as opposed to waiting two to three weeks for a flowsheet assessment.

This speed could allow customers to explore multiple processing flowsheets in a simplified form as part of their due diligence process – for example weighing up a three stage conventional crushing and screening flowsheet against a HPGR circuit.

So far, the crushing and screening portion of the process flowsheet will be covered with the launch of My Plant Planner, but, based on customer feedback, the company plans to expand to the filtration process and other downstream elements.

As to why the company started with crushing and screening, the answer is an obvious one, according to Lambert.

Metso already has Bruno and VPS software (mine to mill assessments) in place – “we don’t have to reinvent the wheel in this regard”, Lambert said – and it is the area of the flowsheet that tends to come with the most equipment options.

“You can have three crushers in parallel, or one big one; a large screen in close circuit, or a smaller one in open circuit, etc,” he said.

It is this flexibility that miners require today. New projects coming to the table are very rarely 20-plus year developments that require a uniform comminution process over their lifetime.

Capex-conscious miners and their investors are instead bankrolling developments that tend to come with less than 10 years of life and are conservative when it comes to throughput. This is with the idea that they will fund the mine life extensions and expansions from existing cash flow when the operation is at full tilt.

These growth plans will inevitably come with the need to amend the process flowsheet down the line – which is where the plant footprint visualisation ability of My Plant Planner could come into play.

Flexibility such as this is also coming into Metso’s equipment line-up, with the company, only last week, launching its flexible FIT™ and smart Foresight™ crushing and screening stations for mining.

The FIT stations are designed with a focus on speed and flexibility, with two stations to choose from – Recrushing station and Jaw station – while the Foresight stations are equipped with smart automation technology including Metso Metrics™, VisioRock™, level sensors and crusher variable frequency drive.

These modular solutions are geared towards reducing capital expenditure and providing shorter lead times. In other words, they offer more flexibility.

It is tools such as My Plant Planner that will highlight just how important this flexibility could be over the life of mine of a chosen operation, providing users with the visibility to help navigate choppy commodity cycles and ensure their operations remain profitable over the long term.

Crushing the mining numbers at Metso’s Tampere facility

Metso’s Tampere, Finland, facility is due to deliver some 1,000 crushing and screening units this year as the company makes full use of the €1 million ($1.15 million) Speedline assembly line it started up in January.

The investment, targeting both efficiency and safety improvements, has enabled Metso Tampere to produce more of its famous Lokotrack® mobile track-mounted crushing units, while also speeding up production of C-series jaw crushers and GP-series cone crushers.

The assembly of a 50 t, track-mounted crushing plant now takes two working days. The serial production line operates in two shifts and has increased Metso’s mobile crushing plant production capacity by 25%.

The majority of these products will find their way into the aggregates industry, but the largest equipment will be seen in mining operations around the world – for example, the Lokotrack LT200 in use at the Altay Polimetally LLP copper mine in Kazakhstan.

IM Editor Dan Gleeson toured the centre last week and found out about the company’s extensive crushing database and how its rock laboratory is offering customers a preview of how its machines could perform.

Piles of rock

Metso’s crushing R&D facility in Tampere is receiving rock samples from all over the world on a weekly and, sometimes, daily basis.

As IM approached the 10-year old rock laboratory in Tampere, piles of rock were waiting outside for testing in a full-scale, enclosed crushing facility configurable with a jaw crusher and either a cone, gyratory, or impact crusher. Various screens were also able to be installed.

Powered by a 300 kW motor and housed inside a roofed facility, this crushing circuit provides customers looking to buy a Metso crusher with the sort of information they only normally receive after the new plant is delivered and commissioned at site.

But, for those not wanting to transport a few tonnes of material to the Tampere facility, Metso has devised a much smaller rock test that only requires a 4 kg sample and tests the hardness, crushability and abrasiveness of the rock in question.

Inside the test centre, manager Ville Viberg talked IM through this much smaller process, explaining the rock test also indicates how quickly a crusher’s wear parts may reach the point of failure – a boon for customers already planning their maintenance shifts years in advance.

Viberg said the company had carried out some 17,000 rock tests to date across the globe, plus some 5,000 crushing tests on the much bigger scale.

This has provided the company with a massive database to refer back to, which it often does in the cyclical mining industry.

On top of this, the company’s Bruno simulation software, mainly used for aggregates applications, offers another level of expertise, allowing users to enter basic feed material and machinery data into the process with the software predicting how the process will perform. Today, there are more than 7,000 users of Bruno, which was developed by Metso all the way back in 1994.

In the future, Metso’s R&D for mining is clear on the direction it is taking – finding solutions to increase energy efficiency and prolong machine life.

This has already seen the company launch its Superior™ MKIII; a gyratory crusher offering 30% higher capacity than other high-speed crushers and 70% lower downtime with a rotable top shell design. The third-generation machine also comes with a five-year warranty for all main components.

The MKIII gyratory crusher was developed in Metso’s mining competence centres with the development headed by the Waukesha centre, in the US, which focuses on mining crushers.

From IM’s visit, it was clear that the more than 100-year old factory in Tampere, which is one of several Metso minerals R&D centres around the world, has plenty of new innovations up its sleeve.

Like the rest of the Metso group, the addition of a digitalised platform like Metso Metrics for Mining – due to be launched next month – will enable the factory to keep developing products to solve the industry’s needs.
