Higher supplies to the UK lift Swiss October gold exports
Supplies from Switzerland to Britain in October reached the highest level since June 2021.
Swedish equipment and tool manufacturer Sandvik Mining (STO:SAND) has added news machines to its CH800 series of mining cone crushers, launching two models that improve productivity and profitability in the mid-range segment.
Sandvik CH860 for high-capacity secondary crushing and Sandvik CH865 for high-reduction tertiary and pebble applications feature higher crushing forces relative to mantle diameter and a 500 kW motor.
The new crushers, says the firm, combine a range of advanced automation features for a more secure and productive process.
“We scaled down our larger Sandvik CH890 and Sandvik CH895 mining cone crushers to create two mid-range models that are even more productive, robust and reliable, and feature enhanced environmental, health and safety characteristics,” says Andreas Christoffersson, Product Line Manager for cone crushers at Sandvik Mining. “Depending on the application Sandvik CH860 and Sandvik CH865 outperform competing equipment in the mid-range segment by as much as 30 percent and deliver a two-fold increase in performance range.”
The intelligent systems in Sandvik CH860 and Sandvik CH865 enable real-time performance optimization, while smart, compact design solutions reduce dynamic loads and minimize engineering and installation work. The crushers feature fewer moving parts than competing models, according to Christoffersson. Non-welded, bolted liners on the top and bottom shell enable safer, easier maintenance.
Both new crushers also feature the company’s ASRi (Automatic Setting Regulation control system) and Hydroset to ensure automatic operation at peak performance around the clock. ASRi constantly monitors pressure, power draw and mainshaft position and automatically adjusts the setting during full load.
“In these challenging times mines are often looking for increased productivity without necessarily expanding their plant,” Christoffersson says. “Sandvik CH860 and Sandvik CH865 are easy to install as replacements to achieve this. In the test site we replaced a similar sized crusher, on the same foundation, to greatly increase final product and significantly extend crushing chamber liner life. The electric dump valve repeatedly proved its tramp iron protection value, reducing costly unplanned breakdowns.”
The equipment was submitted to rigorous testing in a Chinese iron ore mine, with “excellent results,” the company added.
Last month Sandvik revealed plans to relocate its various global mining equipment facilities to India and China from the U.S. and Europe, as part of a two-year business reorganization set to conclude in the next fiscal.
