CERAMIC PARTICULATE MIXTURE COMPRISING COAL COMBUSTION FLY ASH
La presente invención se refiere a una mezcla de partículas cerámicas granuladas en seco, no secada por aspersión, que comprende al menos un 40 % en peso de cenizas volantes de combustión de carbón y entre un 4 % en peso y un 9 % en peso de agua, en donde al menos el 90 % en peso de las partículas tienen un tamaño de partícula de entre 80 μm y 600 μm. (Traducción automática con Google Translate, sin valor legal)
The present invention relates to a non-spray-dried, dry-granulated ceramic particulate mixture comprising at least 20wt% recycled aluminium silicate material and from 4wt% to 9wt% water, wherein at least 90wt% of the particles have a particle size of from 80µm to 600µm. A non-spray-drying, dry granulation process for making this mixture , wherein the process comprises the steps of:(a) forming a precursor material;(b) subjecting the precursor material to a compression step to form a compressed precursor material;(c) subjecting the compressed precursor material to a crushing step to form a crushed precursor material; and(d) subjecting the crushed precursor material to one or more air classification steps to form the mixture.A process for making a ceramic article, wherein the process comprises the steps of:(e) pressing the ceramic particulate mixture to form a green article;(f) optionally, subjecting the green article to an initial heat treatment step;(g) subjecting the green article to a heat treatment step in a kiln to form a hot fused article; and(h) cooling the hot fused article to form a ceramic article.
