A BRIQUETTE AS WELL AS A PROCESS AND APPARATUS FOR THE PRODUCTION THEREOF

摘要

A shaped body, e.g. a briquette, is obtained by compacting a mixture based on granular or powdery glass-forming raw materials, inorganic binding agent and water. Clinker cement is used as the organic binding agent and the raw material is compacted to an apparent density amounting to at least 90 % of the theoretical maximum material density of the dry mixture using a roll press briquetting apparatus. The process comprises adjusting the glass batch quantification to take account of the glass forming constituents of the cement.
