The briquettestrength and the drying briquette density are increased with the increasing of pressure.
随着压力的增加，压块强度和密度都提高。
2
Theoretical analysis on suitable raw coal sizes for briquettes and experimental study on the relation between raw coal sizes and briquettestrength have been carried out.
采用理论分析方法对合理原料煤级配进行了分析，并对原料煤级配与型煤强度的关系进行了实验研究。
3
The effect of feed coal particle size on strength of briquette is discussed when different briquetting process and rank of coalification coal are adopted.
