Abstract

A method for continuous production of a thermally insulating mixture comprising silica particles and opacifier particles, in which a premixed stream comprising a carrier gas, silica particles and opacifier particles is introduced into a fine impact mill, ground and mixed therein, after which the solid is separated from the gas stream, wherein the fine impact mill is an air-stream mill comprising grinding tracks arranged one above the other on a rotatable shaft.
