COMMINUTION and real-time data analysis capabilities have resulted in new applications. However, the main challenge has been in the feed preparation and complexity and cost of the separation technique. “The main drawback of sorting equipment used to be the relatively low capacities and high operating cost, which is being resolved. I would expect, in the medium to long run, technology to improve even further and become capable of handling larger throughputs required for bigger operations.” Digitalisation Fortunately, the ever-increasing capabilities of digitalisation has made designing new energy- efficient equipment – and ensuring it works to its potential – that much easier. Outotec said digitalisation is seen to play a major role in mitigating climate change and its investments in the sector show it is backing that view. Sandvik has looked to bring “digital transformation” to mines and quarries by connecting its CH800i series of cone crushers to its My Sandvik portal “We are continuously investing in ICT to utilise the opportunities of digitalisation,” the company said. “In 2018, our investments amounted to €21 million ($23.6 million), consisting mainly of IT programmes and intellectual property rights.” Metso, too, has been backing the digitalisation trend, with CEO Pekka Vauramo telling IM recently that the company reserved more than €10 million for digital investments in 2018. Weir Minerals has also prioritised digital initiatives, having recently commercialised its Synertrex ® platform, which can monitor the condition and performance of key pieces of equipment in the comminution process. FLSmidth, meanwhile, said in its 2018 annual report: “Digitalisation is a major driver for change and disruption in many industries, including within cement and mining. “While our customers’ final products, basic materials and the machinery required to produce them are at a low risk of being completely ‘digitalised’, there will be radical changes to all parts of the business.” Sandvik has also looked to bring “digital transformation” to mines and quarries by connecting its CH800i series of cone crushers to My Sandvik. This series of connected cone crushers is the first to offer intelligent crushing based on actionable information via the My Sandvik portal, according to the company, “enabling managers and operators to make decisions based on facts, and see areas for improvement directly, increasing uptime and availability”, the company said. Mats Dahlberg, Vice President Lifecycle Service Stationary Crushing and Screening, Sandvik Mining and Rock Technology, said: “New digital technologies will transform the way mines and quarries work. My Sandvik is the first major step in gaining insights into productivity and predictive maintenance that will drive our industry forward.” Despite these examples, Moly-Cop’s Dr Shelley said the comminution sector is lagging 74 International Mining | APRIL 2019
