Breakage behaviour of different

2003-1-8  The breakage probability is described by a single mastercurve comprising the breakage behaviour of different materials (polymers, limestone, glass) of various sizes (95 μm to 8 mm). From the breakage function, the ratio of x / y 50,3 shows the same dependencies comprising all the different materials in a single monotonous curve.

2017-1-1  It can be seen in Table 8 that the specific breakage rate of the 20/28 mesh limestone particles decreased by about 2.5%. In the third test, 20/28 mesh quartz particles were replaced by the same amount of 14/20 mesh (1180/850 μm) particles. This resulted in an additional decrease of 1.5% in the specific breakage rate of the 20/28 mesh limestone.
