The Point-load Test measures the Point Load Strength Index (Is(50)) of rock specimens, and their Strength Anisotropy Index (Ia(50)), which is the ratio of Point Load Strengths in directions that give the greatest and least values. Rock specimens in the form of core (diametral and axial tests), cut blocks (block test), or irregular lumps (irregular lump test) are broken by application of a concentrated load through a pair of spherically truncated, conical platens. The required testing apparatus is light and usually portable.
Feed Sample Requirements:
Block or irregular lump specimens, with a length/height ratio greater than 1.0, and a height/width ratio of 0.3 to 1.0, are also suitable for these tests.
SGS's comminution experts conduct the Point-load Test in combination with other bench-scale comminution tests. The use of many methodologies provides you with a bankable solution that is unmatched in its rigor. Contact us to determine the variability of your orebody.
