Coal fines accumulate in large quantities at coal mining sites, at transshipment points and in most cases occupy useful areas, creating the threat of pollution of the surrounding area. The feasibility of briquetting coal fine is due to its fine condition and the complexity of transportation, the impossibility of burning in standard grate furnaces.
Unlike pelletizing, briquetting is a dry process, whereby pressure, instead of a binder, is used to form agglomerates. Here, coal fines are fed between two rolls, where they are put under extreme pressure, which binds coal particles to each other. The fines are pressed into the briquette shape.
Keywords Binderless briquetting Bituminous coal Kaolinite 1. Introduction Numerous industrial processes require coal in a coarse form for handling, transportation and as a feed for thermal applications. Mining and processing operations, however, inevitably result in large accumulations of coal fines.1 The coal fines constitute up to 12

Jan 01, 1991 1. INTRODUCTION. Renewed interest in briquetting coal has arisen because of i the increasing amounts of fine coal being generated in mining and preparation which are stockpiled or disposed of in tailings dams and lead to uneconomic land use and environmental problems ii the need for easily handled and convenient coal products and iii the demand for smokeless solid fuels.
Sep 24, 2013 COREX FINEX smelting reduction processes require lumpy coal for stable operation. The screened-off coal fines must be briquetted by means of binders to be utilizable for the COREX FINEX processes. Optimal binder types, their amount, and briquetting conditions are identified by systematic experimental analyses. Experimental work is based on a critical review of
A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700 F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.

Coal briquette is made by the coal briquette machine which uses coal dust or coal fine as the raw material. Sometimes we add other materials like the binder or something to make the briquette as most of the coal fine is hard to form together only by briquette machine.
Coal fine briquetting is the process of coal particle agglomeration. The proper particle size and composition of the coal fine will affect the tightness between the coal fine particles, the total specific surface area of the coal fine. The total specific surface area is related to the binder.
Dec 01, 2018 Coal fines with particle size of 2 mm were used for briquetting and this particle size was achieved through sieving.
