A METHOD OF PRODUCING LIGHTWEIGHT CERAMIC SAND PARTICULATES FROM COAL POND ASH AND USE THEREOF

摘要

The present invention relates to fabricating lightweight ceramic sand as a building and construction material. More specifically it relates to a novel process of manufacturing sintered synthetic lightweight ceramic sand particulates directly from pond ash and fly ash as a secondary raw material. The said synthetic lightweight ceramic sand can be used as a building material. The novel feature of the invention is to manufacture low cost lightweight sand at high throughput to compete against the fast depleting natural sand and crushed stones.
