Process for treating fly ash and a rotary mill therefor

摘要

A process for treating fly ash to activate the fly ash so that it may be used as a substitute for Portland cement, with the process including the use of a specialized rotary mill having variably sized and shaped media to increase the surface area of one fly ash component by grinding, avoiding milling a second fly ash component, while roughing up the surface of the second component to increase its surface area.

主权项

1. A method for treating fly ash so that it is usable as a substitute for Portland cement in the manufacture of concrete, comprising the step of: grinding fly ash having at least two components in a rotary mill having variably sized and shaped media such that the mill increases the surface area of the two different components of the fly ash to provide activated fly ash.
