molded at 20 r/min, and the molded samples were sieved
to control the range of particle size of the samples within
5 mm. Second, the sieved samples were placed in a drum
granulator, and the configured binder solution was uni-
formly sprayed on the sample surface. Again, the samples
were placed in a 240×115×53 mm steel abrasive tool for
compaction molding, and the mold was removed after
maintaining the pressure for 2 min. Finally, the molded
samples were placed in a muffle furnace and held at 100°C
for 1h to remove water from the samples, and the dried
samples were calcined at high temperatures to improve
their strength. The test flow is shown in Figure 2.
