CRUSHERS JUNE 2019 • E&MJ 79 can see what is happening. With the help of the analytics and our expertise we can derive an understanding and see where corrective actions are needed." Customers access the analytics over the web via an online portal co-created with Rockwell Automation and Microsoft Azure. Metso Metrics "provides the highest level of cybersecuri- ty and multiple connectivity options to suit your needs," Metso reported. "Accessible through any internet-connected device, you know exactly what is happening with your equipment 24/7." The value added comes from the Metso performance teams, Luukonen said. "It is more about the people," he said. Most customers have capable personnel to track data and adjust maintenance schedules accordingly. Many, however, lack the time or the tools. "We take care of that for the customer and then, of course, share the insights with the customer, so they know what needs to be done," Luukonen said. The team is "trained to spot trends in alarms and aid in interpreting the data for your specific operations," the company reported. "They can provide customized solutions so you can see the benefits right from the start." In early trials, a team was able to save a customer from a costly repair that would have meant a "very expensive shut- down," Luukonen said. Thus, the benefits offered by the service include increased uptime, improved energy efficiency, reduced variability in quality, and a lower overall maintenance cost, the company reported. Luukonen said he anticipates growing awareness of those ben- efits translating into increased demand for the service in the near future. "We had good experiences with the pilot customers," he said. "We are looking forward to expanding that base in 2019." Upping the Reduction Rate FLSmidth reported the next generation of smaller Raptor Cone Crushers is set for release. "We have developed and tested it during the last two years," Sven Hörschkes, global product di- rector, cone crushers, FLSmidth, said. "The XL 250 and XL 350 machines are ready. And the XL 450 should be finalized in the first half of 2019." Designed for the aggregates industry, previous models were advertised as configurable and capable of handling maximum throughput. Comparatively, the new generation offers more power, Hörschkes said. "This enables us to generate a higher reduction rate and min- imize the circulation load in a closed crushing circuit," he said. "By creating a higher pressure we improve the particle shape." The higher reduction rate enables the customer to minimize the number of required machines or to use smaller screens. "By mini- mizing the circulation load you also can decrease to production of sand," Hörschkes said. "In some places sand is not required." Ensuring ease of use and reduced maintenance, the new Raptors require no back-liner material. "They have in the control system a function that optimizes the wear rate," Hörschkes said. "Both will help the customer to change the liners fast, easy and at the right time." The biggest of the three, the XL 450 is ideal for tertiary appli- cations where the customer needs a cubical material in a range
