Abstract
The article states that grinding is the most important process; it determines the efficiency characteristics of the fibrous semi-finished product and the properties of the products made of it. The effectiveness of this process is influenced by some factors, but a tackle is of the most importance. Recently, the issues of selecting and creating the tackle design for wood fibers preparing, in contrast to cellulose and waste fibers, remain significant. In this regard, a scientific approach to solving the issue of creating the tackle design is required for the effective preparation of high-quality wood fibrous semi-finished product. The article presents theoretical studies for efficient evaluation of the existed structures for grinding wood fibers in disk mills. It has been a basis for developing a new geometry of the tackle and predicting its efficiency along with numerous preliminary studies and investigations carried out by various authors. The results of the experimental studies of the grinding process applying the existing structure and the results of the simulated experiment with the developed geometry of the tackle are presented. A comparative analysis of the influence of the design features of various types of tackles on the dimensional and efficiency characteristics and fractional composition of the semi-finished wood fibers was carried out. It was carried out on the basis of the theoretical and experimental studies, as well as the results of other authors studies concerning a grinding process and the influence of the of the semi-finished product features in the preparation of a fibrous semi-finished product in a disk mill.
