To crush a hard rock to a size approximating 1 in. diam., and a soft rock to 2 in. would appear ideal, but in practice it is all crushed to a maximum diameter of 1% to 2 l/2 inches. For a hard ore a drop of 7 to 10 in. is usual, for a medium ore from 6 to 8 in., and for a soft ore from 4 in which a rock beam is failed by bending. Either three point or four point loading (Fig. 8.6) may be used in the test. For a cylindrical rock specimen (diameter d) and the four point loading arrangement as shown in Fig. 8.6, it may be shown that the tensile strength ( t) is t 32 PL/(3 d3) (8.2)
