METHOD OF MANUFACTURING MATERIAL FOR CERAMIC INDUSTRY USING RECLAIMED ANTHRACITE COAL ASH, AND METHOD OF MANUFACTURING CERAMICS USING THE MATERIAL FOR CERAMIC INDUSTRY

摘要

A method for manufacturing raw materials for a ceramic industry is provided to reduce manufacturing costs while producing high-quality ceramics and prevent exhaustion of natural resources by recycling anthracite coal ash. A method for manufacturing ceramics using anthracite coal ash comprises the following steps of: pulverizing anthracite coal ash collected from a reclaimed land; separating the anthracite coal ash with particle diameter of 2.0mm or less and that with particle diameter of 2.0mm or more and 9.0mm or less; drying the anthracite coal ash with particle diameter of 2.0mm or less; and separating the anthracite coal ash with particle diameter of 0.3mm or less from the that with particle diameter of 2.0mm less.
