High-grade silicate material raw material and manufacturing method of high-grade silicate material raw material

摘要

The present invention provides a high-grade silicate material raw material high in solubility to raw materials such as fertilizer and a method for producing high quality silicate raw material. Even by raising the ambient temperature in the furnace, it is possible to increase the content of the inorganic matter of the shell by continuing the exothermic reaction of the rice husk even by burning and removing the flammable organic matter in the shell even by self-combustion of the shell (exothermic reaction) The flame-retardant organic matter remained on the surface of Moromi shell is burned out almost, and the content of non-crystalline silica (SiO 2) is increased to improve the solubility.
