Grinding mill process design
Choosing an appropriate grinding circuit configuration depends on your ore characteristics and mine plan. Outotec has extensive knowledge of comminution technologies and processes to ensure we provide the optimal solution for your needs.
We offer autogenous (AG), semi-autogenous (SAG), ball, rod, and pebble mills in sizes ranging from kWs up to 30+ MW. Our product range also includes a number of unique solutions, including the world’s largest acid-resistant grinding mills, which can operate with extremely corrosive slurry.
Advanced process controls
Our state-of-the-art grinding process control solutions make it possible to stabilize, adjust, and improve your grinding results. These enhancing technologies accompany our grinding mills and make the grinding process more efficient, which adds significant value to the whole concentration process. These technologies include on-line particle size analyzers for the feed and discharge (RockSense and PSI® particle size analyzers), mill charge measurement tools (MillSense®), and advanced process controls (ACT).
TPL™
Our unique TPL™ technology improves grinding process efficiency – the primary grinding process can be intensified for hard ores and material transport can be improved for soft ores. TPL is an environmentally friendly technology used to achieve higher energy efficiency from the grinding mill. Better energy efficiency in the grinding process can also bring significant cost savings to your plant overall.
