A PROCESS FOR THE PRODUCTION OF DOMESTIC OR INDUSTRIAL FUEL BRIQUETTE UTILISING MIDDLINGS OR SINKS FROM CAKING COAL WASHERY OR LOW GRADE CAKING COAL WITH OR WITHOUT ADDITION OF COKE FINES, SEMI ANTHRACITE OR NATURAL COKE (JHAMA) USING INORGANIC BINDER AND WITHOUT USING ANY ORGANIC BINDER

摘要

A process for the production of domestic or industrial fuel briquette which consists in crushing of raw materials like middlings or sinks from caking coal washeries or low grade caking coal having caking index not less than 10 (B.S) and ash content not more than 40 per cent and coke breeze from high temperature coke ovens or beehive ovens or natural coke (Jhama) or semi anthracite, mixing with water and binder, agglomerating the product, drying of the agglomerates and devolatilising the product which is characterised in that coarser crushing of the raw materials to minimise crushing cost and weat and tear on crushers, mixing with less proportion of water, agglomerating by the technique of briquetting are used.
