A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80 passing 188 inch 6350 microns.
T80 refers to the SAG product size in microns transferred to the ball mill circuit. The design procedure chosen by Davy used the SPI and Bond Ball Mill Work Index values to select the required specific energy for both the SAG mill and the ball mill. The other tests were used for comparison and to confirm the chosen result. Then, since used.
