Embodiment Construction
[0025] What the present invention discloses is a kind of method utilizing fly ash to produce fiber cotton, such as figure 1 Shown, described method comprises the following steps:
[0026] 1) Synthetic granulation of raw material fly ash:
[0027] The fly ash is synthesized into granules through a molding machine, and several through holes can be set on the shaped granules. The purpose of setting the through holes is to increase the air permeability of the granules, so that the shaped granules can be burned more thoroughly during subsequent high-temperature melting .
[0028] 2) Raw material mixing:
[0029] Mix the above-mentioned granular fly ash, calcium stone and coke. The mixing ratio varies according to the source of fly ash. Usually, it is: 90% of fly ash and 1% of calcium stone in terms of weight ratio. 2%, coke 8% to 9%. And no matter how much the content of fly ash is, the content of calcium oxide in the fly ash is preferably 20-25% by weight, and the content of s...
