This all comes from the premier design approach we take to finding the best solution to fit the project needs, while exceeding operational goals.

Process knowledge and testing capabilities

At Metso Outotec we have extensive in house process design and sizing capabilities built on unmatched process expertise. With ore grades decreasing, our process team helps to maximize the efficiency of your grinding circuit using Premier™ horizontal grinding mills. Combining process expertise, in house capabilities and an unrivaled product portfolio, we aim to reduce OPEX and maximize efficiency of your operation.

We also have test work capabilities in multiple locations. These are suitable for not only process testing, but also for pilot modeling.

Advanced simulation tools

Metso Outotec Premier™ horizontal grinding mills are supported by the use of advanced simulation tools during the design phase. Our tools use 3D technology and evaluate all parameters of the mill design. Ranging from the mill body, to the open gearing to the bearing system.
These advanced simulation tools provide a comprehensive view to not only optimize your Premier™ horizontal grinding mill design, but ensure long term trouble free operation and as far as possible eliminate unplanned downtime.
