Metso Outotec complements stirred mills with complete Stirred Mill Plant Units for fine-grinding solutions

Metso Outotec is launching yet another powerful product in its range of concentrator plant units – the complete Stirred Mill Plant Units for efficient fine grinding. The units integrate Metso Outotec’s comprehensive stirred mills portfolio with other proprietary technology products like hydrocyclones, samplers, analysers, and slurry pumps. To complement this, Metso Outotec can offer a process performance guarantee based on testing of a representative sample, and a TCO calculation co-created with the customer. These allow easy evaluation of the feasibility and benefits of the fine grinding solution.

“With industry-leading plant configurations, the Metso Outotec Stirred Mill Plants feature frontrunning energy efficiency as well as a compact plant design that reduces footprint requirements and makes even the brownfield installations easy. All our stirred mills are part of the Planet Positive product portfolio, thanks to the sustainability benefits they deliver. The solutions cover equipment and a comprehensive range of services, including parts, to ensure continuous operation of the plant at an optimal performance level,” explains Subhashis Ghosh, Vice President, Concentrator Plants and Process Islands at Metso Outotec.

The Metso Outotec stirred milling technologies portfolio consists of Vertimill®, HIGmill™, and Stirred Media Detritor (SMD) mills. The mills are based on gravity-induced and fluidized technologies, allowing for an optimum equipment solution for all comminution circuits covering secondary, tertiary, fine, ultrafine, regrind, and lime slaking applications. All mills are suitable for a large range of product sizes. The standardised range includes chamber units of up to 50,000 litres as well as the world’s largest industry units with up to 6,500 kW of installed power. The optimised use of floor space reduces investment costs, and installation is easy.

Metso Outotec has over 50 years of experience in developing, testing, and delivering stirred mill technology. This includes over 500 installations worldwide in a range of applications and from an industry-leading portfolio.

Cited benefits include a full fine-grinding solution and plant delivery under one roof, total cost of ownership calculation, from engineering to operation and already proven milling, classification, and pumping technologies. Metso Outotec offers a comprehensive testing program, followed by process design and potential plant performance guarantees with superior plant design for safe and easy plant operation and maintenance. The solution also has flexibility in layout, with an optimised footprint to suit many arrangements as well as fast and safe prefabrication and site construction thanks to pre-engineered modules. The standalone solution minimises interruption to an operating plant during construction and commissioning of a Stirred Mill Plant Unit.
