METHOD OF TREATMENT OF FLYING ASH AND USED FOR THIS ROTARY MILL

摘要

1. A method of processing fly ash, as a result of which it can be used as a substitute for Portland cement in concrete production, comprising the step of: grinding fly ash having at least two components in a rotary mill having working bodies of various sizes and shapes, thus that the mill increases the total surface of these two different components of fly ash to provide activated fly ash. 2. The method according to claim 1, wherein the first component of the fly ash includes non-spherical particles, and the second component of the fly ash includes spherical components. The method according to claim 2, wherein the working bodies of various sizes and shapes reduce the size of the nonspherical components of the fly ash, while grinding the surface with the spherical fly ash component, thereby increasing the total surface of both components. A method according to claim 3, wherein the total total surface of the fly ash that has undergone grinding is increased by at least 30%, thereby giving the fly ash more reactivity. The method according to claim 1, wherein the rotary mill grinds calcium together with the components of fly ash. The method of claim 5, wherein the calcium comprises at least one of the following: quicklime, slaked lime, calcium carbonate, calcium formate, calcium nitrate or a related calcium compound. The method of claim 5, wherein the rotary mill output includes calcium milled together with fly ash to form calcium coated fly ash particles. The method of claim 7, wherein the calcium coated fly ash particles are ground together with the fly ash in a subsequent step.
