64 E&MJ • SEPTEMBER 2018 www.e-mj.com PROCESSING SOLUTIONS Sandvik recently introduced its CH800i series of connected cone crushers, de- scribing them as the fi rst to offer in- telligent crushing based on actionable information via the My Sandvik portal. This, according to the company, enables managers and operators to make deci- sions based on facts, and see areas for improvement directly, increasing uptime and availability. Included in the new crusher lineup's feature list are: Advanced automation – Automation fea- tures continuously measure and compen- sate for crusher liner wear, while Hydroset and an electric dump valve automatically provide overload protection to let tramp iron or other uncrushable material pass through. Automatic Setting Regulation (ASRi) automatically adapts crushers to variations in feed conditions. Tougher crushing – The CH800i system comes with a range of upgrades, includ- ing a 65% stronger main shaft, and top and bottom shells that are up to 50% stronger than previous models, offering more reliability and higher availability. Quicker maintenance – The system has bolted rather than welded top and bot- tom shell liners to reduce maintenance time. Since no welding is needed when changing liners, the process is up to 90% faster. All-new or as-new – The CH800i crusher system can be purchased as a completely new crusher, or customers can select a Sandvik Reborn solution, which replaces an existing crusher with a new one and reutilizes existing auxiliaries and infra- structure. This "plug-and-play" approach minimizes disruption and maximizes pro- ductivity, while offering up to 40% cost savings compared to a complete crusher system, according to the company. Sandvik CH800i crushers connect using My Sandvik, a set of intelligent services that the company said monitors and measures productivity and provides actionable data and interactive tools in- cluding e-commerce. Using the My Sand- vik web portal, customers can access dig- ital service solutions that include Insight, which enables user-friendly and com- prehensive data and fl eet overview; and Productivity, which provides up-to-date productivity and utilization reports for any period of time, as well as alerts about possible malfunctions or service needs. According to Sandvik, My Sandvik Pro- ductivity delivers analyzed, machine-spe- cifi c data for comprehensive performance comparison between a customer's Sandvik machines and allows data to be exported from the service. As a result, end users will have a 360° view of the operational status of their Sandvik equipment. Based on the information provided by My Sandvik, users can improve operational effi ciency and do preventive maintenance planning. "New, digital technologies will trans- form the way mines and quarries work. My Sandvik is the fi rst major step in gaining insights into productivity and predictive maintenance that will drive our industry forward. It's great to offer our customers a service that will truly make a difference to their profi tability," said Mats Dahlberg, vice president of lifecycle service station- ary crushing and screening, Sandvik Min- ing and Rock Technology. New Comminution Energy Curve Tool Enhancements Now Available The Coalition for Energy Effi cient Com- minution (CEEC), an Australia-based or- ganization that serves as a platform for dissemination of the latest technical fi nd- ings on effi cient comminution practices, has released the fi rst new enhancement to its free suite of energy curve tools — specifi c energy cost curves — to help miners and METS (mining, equipment, technology and services) companies con- sider the impact of energy costs and iden- tify options to improve energy effi ciency of comminution circuits. This work is part of a $469,000, three-year CEEC Advanced Energy Curves Project funded by the Queensland govern- ment, METS Ignited (an Australian gov- ernment industry growth center) and the mining industry via CEEC. Miners and METS users can now in- put their latest plant data from differ- ent sites and equipment options via the CEEC website to benchmark and improve performance using the newly enhanced curves. Using real data, according to CEEC, will help them to assess the im- pacts of planned or actual improvements. The specifi c energy-cost curves are important because the variation in elec- tricity price directly impacts the econo- mic value that can be achieved by com- panies employing energy effi cient commi- nution technologies. CEEC said a simple model has been developed that can be used to estimate availability of electricity generating assets near a mine. This can help operators and METS companies consider which mines are best suited to comminution and energy improvement and which projects represent the greatest return on investment. The fac- tors included in the model are the average industry electricity price of the country where the mine is based and the geographi- cal proximity to electricity generator assets. The Sustainable Minerals Institute– Julius Kruttschnitt Mineral Research Center's (SMI-JKMRC) senior research fellow, Dr. Grant Ballantyne, is leading the research component of the project. Sandvik Says New Crusher Line is Connected – and Tough Sandvik's line of CH800i cone crushers includes the top of the line 1,000-hp CH895i, along with the CH890i, CH870i, CH865i and the 670-hp CH860i.
