:: The Benefits of IsaMill Testing

As the processing of modern ore bodies become more challenging and target grind sizes get finer, conventional ball mill technology becomes less energy efficient, making other fine grinding options more attractive. One fine grinding technology option is the IsaMill. The IsaMill is a grinding technology based on high intensity stirred milling, using inert media that was specifically developed for processing fine grained ore bodies. The IsaMill’s reduced energy and media requirements have proven to be a viable capital investment for fine grinding applications.

JKTech Lab Services has a 4.0 Litre capacity IsaMill for conducting the IsaMill test. The primary output from an IsaMill test is known as a ‘signature plot’. This plot relates Specific Energy (kWh/t) to product particle size (microns).


The signature plots for the P80 (80% passing size) and the P96 (96% passing size) are shown below for a particular test.
