JK Bond Ball Mill Test JKTech

an average work index of 15.5 kWh/t. A very broad range of results was received, characterising the ‘standard ore’ from medium to very hard. A disappointing result considering the reliance on this test globally for design and optimisation. An improved method using less mass compared to the Bond Ball Mill Work Index test.
