Title:
METHOD FOR GRANULATING INORGANIC COMPOUND
Document Type and Number:
Japanese Patent JP3704612
Kind Code:
B2
Abstract:
PURPOSE: To easily granulate an inorganic compound by only mixing, by adding two components of the decomposed substance of starch and polyol at specified ratio in the case of granulating the inorganic compound.
CONSTITUTION: In the case of granulating an inorganic compound such as a natural mineral or ferrite, ≥3wt.% decomposed substance of starch of DE 2-40 such as potato starch or tapioca starch and 1.5-10wt.% polyol such as glycerol or ethylene glycol are mixed with the inorganic compound. In such a way, the inorganic compound in a wide range is granulated without necessitating a specific device, and also an excess process such as drying is unnecessary because water is not used. Further, substance excepting the inorganic compound may easily be removed by an operation such as burning. The decomposed substance of starch is porous and glycerol or ethylene glycol is desirable as polyol and the mixing ratio of both is preferably (80-55):(20-45) by weight.
