example, in flowsheets including three stage crushing and conventional grinding, the range assists SAG/AG circuits with pebble crushing and optimises particle size distribution for lump ores and heap leach applications. The Sandvik 800i crushers are also suitable in high pressure grinding roll (HPGR) circuits. They crush more and deliver finer particle sizes to the down stream processes. “With the latest Sandvik 800i crush ers, we can produce much finer product (down to mill feeds of sub 6 mm) from our crushing and screening circuits, ultimately resulting in improved milling and overall process performance. This translates into less energy consumed and reduced wear in downstream processes. In other words, we allow customers to crush more to grind less,” says Ahlqvist. “The ‘crush more to grind less’ approach is a perfect fit for HPGR and mill processes, which are generally known to consume a lot of power. The finer the material that goes into HPGR and mills, the less the energy required in those downstream pro cesses,” concludes Taylor. 

connected Sandvik equipment to provide a complete overview of the entire opera tion. Customers can look at the status of their connected equipment, communicate across teams, view alerts and notifications, pro-actively order spare parts, and much more. “With the new SAM mobile app for iOS and Android, customers can have an overview of their crushing fleet, moni tor equipment data and key parameters, receive alarms from the ACS system directly in their pocket and get recommended actions, created to help them solve issues more quickly,” says Ahlqvist. Of course, adds Taylor, a key benefit here is the potential for remote support. “Through digital solutions, customers can get help remotely without the need to wait for travelling technicians. Remote support gives the customer access to Sandvik’s vast crushing and screening expertise directly to their site, which is where they need it most,” says Taylor. The upgraded Sandvik 800i cone crusher range also aligns with the global push towards energy efficiency. For

guidance helps operators to achieve their targets without the concern of losing shifts due to downtime,” explains Taylor. Meanwhile, maintenance person nel have access to an improved historical and operational data log, pro viding a comprehensive overview of the crusher’s performance. “The inclusion of 90-day historical logs allows for in-depth analysis and tracking of the equipment’s performance over an extended period,” says Ahlqvist. The new automation system offers engineers more opportunities to monitor, analyse and optimise the crusher’s per formance. The ability to create crusher programmes and finetune system limits enables a more customised and optimised operation. Performance optimisation is possible through insights on feed condi tions, load cycles, pressure distribution and uncrushable objects. With the growing move towards digital systems in mind, the upgraded Sandvik 800i crushers are ready to be connected to the SAM by Sandvik cloud-based digital assistant.
