Crushing Work Index Untuk Granit

related to the point load index with 50 mm cores Is50 as follows Beside the diametral test, the axial test and the irregular lump test have also been proposed (see Figures 2b and 2c). Strength anisotropy can also be assessed by using the point load index as suggested by Broch (1983) who proposed an anisotropy index Ia equal to 2.3 Uniaxial Tension

    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 m (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
