Shap Beck is a 1 million tonnes/year limestone quarry benefiting from the extensive use of InsightHQ
Hanson's Shap Beck quarry near Penrith, in the county of Cumbria, North West England is reaping the benefits of increased use of Trimble's state-of-the-art lnsightHQ quarry management portal for web browsers and mobile devices. ABE editor Guy Woodford visited the quarry to learn more about how lnsightHQ's sensor, cable and software-based measuring of extraction, processing, and load-out is enabling the quarry to maximize its efficiency and performance.
Having claimed to save £152 (€169) a day and £38,000 (€42,170) a year since 2012 by using Trimble's InsightHQ product to optimize onsite excavator to hauler material loading, Shap Beck manager, Robin Gillespie, was very open to increasing lnsightHQ's use at his 1 million tonnes/year limestone quarry."It showed our excavator was under-loading the haulers before by 10-15%, something that was not obvious to the human eye," explains Gillespie. "It led to us adding some side extensions onto our dump trucks, allowing us to maximize the carrying potential of each truck." Gillespie says he and his Shap Beck colleagues were first introduced to lnsightHQ in 2011 by visiting members of Hanson's parent company HeidelbergCement's Competence Centre Management (CCM) team, who asked Gillespie if he'd like to trial it."Now we also use it to measure daily production output through average tonnes an hour readings at ten-minute intervals. These readings are taken from material on our three most important conveyor belts situated around the quarry. With InsightHQ, I can see how much material is being put into the primary crusher, how much saleable product I've got left after the scalping and waste removal process, and I can also learn how much of this saleable product is kiln feed limestone, that we can supply to Tata Steel, our biggest single customer, who operate the Shap Fell processing plant nearby. Around 650,000 tonnes of our annual production is kiln feed limestone for Tata Steel, with one of our three key conveyor belts dedicated to handling the product."
"With InsightHQ I can see how much material is being pit into the primary crusher, how much saleable product I've got after the scalping and waste removal process", says Robin Gillespie.
The detailed material-processing performance reports emailed to Gillespie and management colleagues at the start of each day enable them to take swift action to tackle any problems and to obtain vital current product inventory data. InsightHQ can also offer "Snapshot" reporting on performance. Updated every minute, this covers individual product processing data, product processing by customer, individual excavator efficiency, individual conveyor throughput, email or text alerts to deviations in average individual conveyor material throughput, and details of material processing costs for that day and previous days. You can also view changes over time by adjusting reports to take in specific shift, day, week, month or year.
Gillespie says that since May 2016, and following regular discussions with Julian Athawes, director of Halomec, Trimble's LOADRITE distributor in the UK, he and his management team have used InsightHQ to access Shap Beck's primary crusher kilowatt usage per hour data, conveyor running time figures, and conveyor black belt time data (how long the conveyor is not carrying any material). "Having this tool and other things we do at Shap Beck is light years ahead of any other quarry I've worked in," adds Gillespie. "Having the ability to analyze kilowatt usage of the primary crusher means we can link it back to the fragmentation of the blasted material. The better the fragmentation from the blast, the less energy is used by the primary crusher to process material."

Gillespie, who also manages Hanson's Low Gelt quarry, an 100,000 tons/year sand quarry near Carlisle, is looking to embrace other quarry management technology companies to improve the Shap Beck operation. "I'm looking to work with WipFrag, a Canadian company that specializes in photo analysis of blast fragmentation, so we can learn how to obtain better blast consistency. And I'm interested in what technology we can use for stockpile value management."
Shap Beck quarry is keen to meet growing demand from Tata Steel's Shap Fell site for kiln feed limestone which is burnt at Shap Fell and used in large-scale lime production for steelmaking at a number of UK steelworks, including Tata Steel's Port Talbort site in South Wales. As a result, the quarry is looking to extend its current 218-acre site by 40 acres. A planning application will be submitted to the Lake District National Park Authority in Q4 2016. Shap Beck has a Review of Mineral Permission (ROMP) application to 2042. Gillespie says that single-sized -31.5 mm limestone products will start being transported by rail from Shap Beck quarry to Wigan in Lancashire later this year. "It will be redistributed by road from there to central Manchester and supplied to concrete plant customers. We used to use the rail line until 2014, when SSI UK went bankrupt and closed the Redcar steelworks."
At Shap Beck quarry, limestone is extracted by blasting, collected by a varying number of wheeled loaders and excavators - with Shap Beck using a Caterpillar 966M XE, Volvo L 150, Volvo L220, Volvo L250 (L220 and L250 fitted with InsightHQ), and a Hitachi ZX870 excavator - and loaded onto two Caterpillar 775D and one Caterpillar 771D rigid dump truck. The material is then hauled an average of 500 meters and put through a roll grizzly feeder,followed by a Baxter ST5042 primary jaw crusher, capable of processing up to 375tonnes/ hour of material, a scalping screen and two Wilemanwashing barrels. After this, the material goes to a near 1 km field conveyor that takes the crushed material to a three-deck HewittRobins screen, from which the - 125 mm +31.5 mm kiln feed limestone for TataSteel's Shap Fell plant is produced. Oversized material goes to a secondary crushing and screening phase, resulting in concrete aggregates for Hanson's concrete plants near Carlisle. Shap Beck also produces agricultural limestone products. Further emphasizing the quarry's product diversity, Shap Beck has a 25,000 tonnes/year industrial powders plant producing a cement-type product for Francis Flower, who supply filler for asphalt to major names including Cemex UK.
Of the Caterpillar 966M XE wheeled loader's performance, Ben Strickland, assistant manager at Shap Beck quarry, says: "We've got VisionLink on the 966M XE and our two Cat 7750 haul trucks, and we've found that the 966M XE uses 25% less fuel than the Cat 966H we had before. Having VisionLink enables us to do weekly analysis of the 966M XE and 775D RDTs fuel usage and idling times. "I'd like telematics data from all our machines to be available via InsightHQ - whether it be originally captured by VisionLink or Volvo's CareTrack solution," adds Gillespie, who works at Shap Beck alongside 21 full-time colleagues and up to five full-time contractors. Hanson has also introduced InsightHQ into some of its other UK quarries where it's analyzing excavator and hauler load-out. These include Craig-yr-Hesg near Pontypridd, south Wales; and Criggion in Shrewsbury, Shropshire. Clearly converted to the benefits of cutting-edge quarry management software solutions, it will be interesting to return to Shap Beck quarry in a few years time to see just how much Gillespie and his team have further embraced all it has to offer.
