Advantages
Horizontal layout
The horizontal layout enables a plugflow design. This avoids short circuiting and makes the mill far less sensitive to process disturbances. The horizontal design allows the mill to start under load and translates to simpler maintenance.
Low installation cost
Low height, small crane lifts and simple under-floor media system. Large scale mills and open circuit operation. This means less mills, less classification, simple circuit layout and lower installed cost.
Energy efficiency
Simply energy efficiency is about media size. Smaller media has more surface area and higher media/particle collision frequency making it more efficient. The high intensity in the IsaMill™ means small media can break coarse particles. The large scale of the IsaMill™ makes that efficiency available to mainstream grinding.
Accurate scale-up
With proven one-to-one direct scale up from laboratory testwork, installing IsaMill™ technology significantly reduces project risk.
High intensity
This high intensity grinding technology (>300kW/mm3) requires a much smaller footprint than conventional grinding technology – the grinding volume of the IsaMill™ is about one tenth the equivalent ball or tower mill.
Open circuit configuration
While other grinding require closed circuit cyclones and high recirculating loads the IsaMill™ achieves a much steeper product sizes distribution in only a single pass.
Simplicity in maintenance
Continuous development and improvement of the IsaMills™ from their first installation in 1994 has resulted in a grinding machine that not only offers superior performance but also increased component life and decreased costs culminating in a reduction in maintenance and operating costs.
Large scale
Mills are available from 75kW to 8MW. This make the efficiency and process benefits of inert grinding available to large and small tonnage operations.
Improved recovery
Inert Grinding media produces clean, fresh mineral surfaces that often improves downstream processing performance. The steep size distribution also benefits flotation and leach recovery as well as assisting downstream materials handling.
