Spheres were produced from an iron‐ore concentrate by balling and subsequent shaping, and cylinders were cut from these spheres. Experimental data are presented, correlating the factor L / D 2 for the spheres with the failure stress of the cylinders. The latter was measured by the diametral compression (Brazilian) test. The results confirm the direct proportionality between the two, but only above a minimum level of agglomerate matrix strength. At less than 120 kPa the relationship may become complex. A qualitative explanation is offered in terms of the stress‐deformation behaviour of the spheres and cylinders.
