PREPARATION OF WOOD FIBER SEMI-FINISHED PRODUCTS IN KNIFE MACHINES OF VARIOUS MODIFICA-TION
UDC 676.154.3
Abstract
In this paper, we consider the results of a study of the influence of the design and technological parameters of grinding machines of various modifications on the quality of wood pulp.
According to the results of processing multifactor experiments implemented according to the second-order B-plan, a mathematical description was obtained of the dependence of the degree of grinding of pulp on the gap between the grinding disks, wear of the segments, the rotational speed of the lower screw and the concentration of pulp. The obtained regression models are adequate to the process and can be applied in practice for predicting the qualitative characteristics of wood pulp depending on the parameters of the grinding process.
Analyzing the obtained experimental data, it can be noted that such factors as the state of the surfaces of grinding disks, the gap between them and the concentration of wood fiber have the greatest influence on the degree of grinding of the mass. Evaluation of graphical dependencies allows you to determine the extent to which you can vary the operating and design parameters of the grinding process to obtain wood fiber with the required grinding quality.
