9. REPORTING TEST RESULTS 9.1 Report the Wet Ball Mill value to the nearest whole number. Note 3—This test furnishes valuable supplementary data pertaining to the quality of the aggregate portion of flexible base material. The Wet Ball Mill test is more reliable than the Los Angeles abrasion test in evaluating the quality of base materials.
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...
