An essential element for sustainable use of renewable resources is an efficient comminution process for which the relation between energy input and size reduction is of great importance. Fine comminution of beech, oak, and spruce wood chips in cutting and hammer mills at different moisture content levels is investigated. The influence of the different process parameters as well as the size reduction performed by the hammer and cutting mill on the specific comminution energy is reported and the particulate properties of the comminution products are reported. Considering the energy requirements, functional relations were derived from the experimental results, which describe the relation between comminution energy and size reduction.

木材粉碎–工艺参数的影响

可持续利用可再生资源的基本要素是有效的粉碎过程，对于这一过程，能量输入和尺寸减小之间的关系非常重要。研究了在不同水分含量的切割机和锤磨机中对山毛榉，橡木和云杉木屑的细粉碎。报告了不同工艺参数的影响以及锤子和切割机执行的尺寸减小对比粉碎能的影响，并报道了粉碎产物的颗粒性质。考虑到能量需求，从实验结果推导了函数关系，该函数关系描述了粉碎能量与尺寸减小之间的关系。
