Any other information on results incl. tables

Sieves:

The particle size distribution obtained for sieving sampleCarboNeXTis showed in Table 1.

The%, cumulativecolumn, contains for each fraction obtained the percentage in weight of the same fraction and of those of the lower fractions.

Table 1

Particle size distribution ofCarboNeXTsample

SIEVE OPENING, mm	%, in weight	%, cumulative
>5,0	46,0	100,0
5,0 ÷ 4,0	3,3	54,0
4,0 ÷ 2,8	3,6	50,7
2,8 ÷ 2,0	5,5	47,1
< 2,0	41,6	41,6

 

Particle size analyzer:

Tests were conducted dispersing the fraction in the air with particle size lower than 2.0 mm of theCarboNeXTsample using the specific sampling unit called SCIROCCO 2000.

The results of the determination on the fraction with particle size lower than 2.0 mm are shown in Fig. 2.

The figure shows the average voluminal diameter as well as that for which the accumulative particle size distribution assumes a respective value of 90%, 50% and 10% in addition to the differential distribution for each fraction and the corresponding graph as well as the measurement parameters and the indications of the powder sample and the operator.

In Table 2, the average voluminal diameter is found as well as that for which the accumulative particle size assumes a respective value of 90%, 50% and 10%.
