| Abstract: | Some experimental results of research on cold strength of briquette with agglomerant are introduced in this paper. The industrial briquettes are made of bituminous coal and the agglomerant is high molecular polymer. The effect of granularity, pressure and moisture content on cold strength of briquette is studied. The results are useful for the industrial process. The experiments indicated that the granularity of raw coal has notable influence on the cold strength, and the moisture content is effective on the dispersion of agglomerant, especially for the hydrophilic agglomerant. |
