Example Embodiment
[0011] The features of the present invention and other relevant features are described in further detail below through the embodiments, so as to facilitate the understanding of those skilled in the art:
[0012] Reality
[0013] After mixing the above components, roll them into balls in a disc granulator, or extrude them into cylinders, and dry them at a temperature of 80°C-250°C. The particle size of the above-mentioned expanded perlite and other filling materials is ≤1mm .
[0014] In the above embodiments, the carbonized rice husks are effectively bonded together into granules by using a high proportion of carbonized rice husks in combination with various fillers and various binders. Tests show that the product has a bulk density of less than 0.6 and a melting point of around 1400°C.
