SAG Mill Testing - Test Procedures to Characterize Ore

For the abrasion test, a 3kg sample of 53 x 37.5mm rocks is used. The sample is rotated in a 30cm x 30cm tumbling mill for 10 minutes, after which the product is submitted for a particle size analysis. By convention, the abrasion parameter (ta) is equal to 1/10 of the t10 achieved in the abrasion test.

Bond Work Index - an overview | ScienceDirect Topics

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% 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 index determination for the material size of interest, or by chaining individual work index calculations using multiple laboratory work index ...
