The aim of this work was to determine the effect of compaction parameters of shredded logging residues on the durability of obtained briquettes. Logging residues have a different composition than raw materials currently used in the agglomeration process, because they contain a high amounts of bark, needles and mineral contaminations. The innovation of this study results from the type of biomass used in the research – non-homogenous fraction containing significant amounts of needles and non-woody parts. Correlation between the physical properties of obtained briquette and raw material parameters and the course of briquetting process were determined. Biomass was compacted in a special designed closed die. The investigated material with moisture contents of 10, 15, 20% was compacted at temperatures of 22 and 73 °C. Single briquettes with a density from 799 to 1215 DM kg·m⁻³ at the compaction index values ranging from 27.73 to 35.37 (J g⁻¹)/(g·cm⁻³), respectively were obtained. For both temperatures 22 and 73 °C, the highest values of durability coefficient were obtained for 10% moisture content and they were 16% and 22%, respectively which were not satisfying durability. It was also found that the temperature of material during agglomeration influences its susceptibility to compaction and durability of obtained briquettes and that it is more advantageous to carry out the compaction at a higher temperature. On the other hand, the higher temperature of the agglomeration process affects the increase in specific work of compaction which to a small extent depends on the moisture content of the material.

这项工作的目的是确定切碎的伐木残渣的压实参数对所获得的团块的耐久性的影响。伐木残渣的组成与集聚工艺中目前使用的原材料不同，因为它们含有大量的树皮，针叶和矿物污染物。这项研究的创新来自于研究中使用的生物质类型-非均质部分包含大量的针叶和非木质部分。确定了所获得的团块的物理性质与原料参数之间的相关性以及团块化过程的过程。生物质在特殊设计的密闭模具中压实。将水分含量为10％，15％，20％的研究材料在22和73°C的温度下压实。^-3在压实指数值范围从27.73到35.37（j克^-1）/（克·厘米^-3），分别获得。对于22℃和73℃的温度，对于10％的水分含量，获得了最高的耐久性系数值，分别为16％和22％，这不满足耐久性。还发现，附聚过程中材料的温度影响其对压实的敏感性和所得团块的耐久性，并且在较高温度下进行压实更有利。另一方面，附聚过程的较高温度影响压实比功的增加，这在很大程度上取决于材料的水分含量。
