Figure 5 presents the interaction curves based on the
response (surface area), along with the corresponding con-
ditions outlined in Table 2. The interaction curves from
the identical ANOVA analysis are presented in Figure 6,
with the only distinction being that the response was the
pore volume instead of the surface area. As expected, the
changes in the operating parameters lead to changes in the
behavior of surface area, mirroring the patterns observed in
pore volume. This correlation is consistent with the close
association between the two properties. The results indicate
a significant increase in surface area as masses increase,
and a similar trend is observed with higher intensities. It
is thought that under these conditions, collisions are more
likely to occur within interparticle spaces, resulting in size
reductions and consequently an increase in surface area.
The responsiveness of surface area to mixing time exhibits
variability, as illustrated by the interaction plot. This plot
indicates a decrease in surface area for short time intervals
(t 16 minutes) and an increase for longer time intervals (t
16 minutes), resulting in a quadratic pattern. Variations
Figure 5. The interaction plots show the effects of mass of biochar (a), mixing time (b), and mixing intensity (c) on the surface
area of biochar. The findings indicate that increasing both the biochar mass and the intensity of resonant vibrations enhances
the surface area of biochar particles. Notably, there is a quadratic effect on the surface area observed over different time
intervals. Under specific conditions (8.5g biochar mass, two minutes mixing time, and 75% intensity), the surface area peaks
during the process
Figure 6. The interaction plots illustrate the impact of biochar mass (a), mixing time (b), and mixing intensity (c) on biochar
pore volume (response). Another ANOVA experiment, resembling the one described in this article, was undertaken to examine
how operational parameters of resonant vibratory mixing affect biochar pore volume. The findings offer additional insights
into the physical alterations occurring within biochar particles inside the mixing vessel
