Horizontal grinding for enhanced energy efficiency, product size & availability

The IsaMill™ has real-world success in 150+ metalliferous installations across 23 countries. It's the world's only horizontal layout fine-grinding mill, so it avoids short-circuits, is highly efficient and gives the highest availability.

The IsaMill™ is a highly efficient, horizontal fine grinding mill designed to improve the grinding process in mineral processing. The effectiveness of this regrind mill is proven in 151 metalliferous installations across 23 countries since its launch in 1994.

• Accurate Scale-Up: The IsaMill™ offers 100% accurate scale-up, consistently delivering reliable results across installations.
• Easy Maintenance: The IsaMill™ is designed for easy maintenance, with no height safety concerns and quick access to components in minutes.
• Open Circuit Configuration: Its open-circuit configuration delivers a steep particle size distribution, eliminating the need for internal screens or closed circuit cyclones.
• High Intensity: The IsaMill™ provides high-intensity grinding, ensuring effective and efficient processing of materials.
• Improved Recovery: The horizontal plug-flow design prevents short-circuiting, ensuring reliable operation and improving flotation and leaching performance downstream.

Using its unique horizontal configuration, the IsaMill™ delivers superior energy efficiency and availability compared to traditional vertical grinding mills. Its design allows for the use of low-cost ceramic media, reducing overall costs and enhancing the grinding process. The mill operates with a slurry flow that maximises particle contact, achieving optimal breakage and better liberation of valuable minerals. This results in a consistent product size with sharper distribution, improving downstream processes such as flotation and leaching.

The IsaMill™ excels at fine and ultrafine crushing and grinding of mineral ore particles, including regrind and coarse feed materials. It offers better energy intensity than ball mills and is notably more compact, requiring less structural support. It is a cost-effective solution for grinding processes in industries such as copper, lead, zinc, and gold.

With a proven track record in the field, it provides a reliable and scalable solution for iron ore grinding to a precise particle size, maximising recovery and enhancing the overall efficiency of grinding in mineral processing operations.

In short, IsaMill™ reduces the energy cost, media cost and capital cost of fine-grinding. Visit our page for further information on how IsaMill™ works.

The IsaMill™ is used extensively in base metals, PGM, gold processing and magnetite grinding applications. And the power capacity of an IsaMill™ ranges from 75kW to 3.8mW.
