摘　　要：分析了原料粒度组成、成型压力以及成型水分等因素对型煤成型的影响,介绍了改变原料的粒度配比、成型压力以及成型时添加的水分的实验研究,揭示了原料粒度组成、成型压力和成型水分对型煤强度的影响规律。实验研究表明,随着0.5mm以下粉煤的增加,型煤强度有增加趋势,但是过多的小粒径粉煤对成型不利,粒径小于0.9mm粉煤占80%时强度最佳;成型过程中最佳的成型压力为25MPa;成型过程中添加的水分为10%时对成型最有利。This paper shows such factors as grain size composition of the feedstock,forming pressure and the mois-ture content that impact the forming of the briquettes through analysis and research.The experiments indicated that with the increase of the amount of fine coal of which the size is below 0.5mm,the strength of briquettes is also improved.But if the amount of fine coal is too much,it is disadvantageous to the forming of the briquettes.Optimum strength can be ob-tained when the proportion of fine coal whose size is below 0.9mm is around 80%.For best forming of the briquettes,it is advisable to have the pressure of 25MPa and the moisture addition of 10%.
