HPGR service
The dynamics and variables of a process plant can be quite demanding on the installed equipment. Careful consideration needs to be given in order to gain the most from the installed power. A well-tuned HPGR will be able to cope with these dynamics and provide opportunities to increase efficiencies, not only in the HPGR plant, but also from the equipment upstream and downstream.
Whether you're looking for more uptime from your HPGR, reducing the load on downstream equipment, looking for maintenance improvements or need assistance with planning, supervision or the complete change out of a machine, we have a solution to meet your needs.
Through your available data, and analysing any problematic situations, we can work with your existing team to tailor set points and make adjustments to improve and optimise your current processes. We have a team of comminution experts (total system) that understand the crushing, screening and grinding mills, etc. that would be part of your process.
