摘要

Process for obtaining refractory products with high content of electrofused mullite and very low vitreous phase content, characterized in that, starting from electrofused mullite ingots, the formation of large crystals is caused, by controlling the cooling of the ingots, proceeding after its chopping, quartering and primary crushing to selective secondary crushing, by means of cylinder or hammer mills, the first of which must be provided with individual cylinders and with a fine mechanism for regulating the pressure, while the hammers they must have a variator at will of the speed of rotation of the hammers, to increase or decrease the impact of the hammer on the material.
