Abstract
The steady trend towards improving the process of grinding semi-finished fibrous products in pulp and paper production is caused by an increase in consumption volumes and the desire to reduce energy costs while improving the quality of the finished product. Changing the grinding parameters, which include the concentration of the fibrous mass, the rotor rotation speed, and the gap between the rotor and stator disks, allows you to control the characteristics of the resulting products over a wide range. The article examines the influence of the concentration of fibrous mass on the properties of the finished product. The physical and mechanical characteristics of the finished paper castings were assessed, including the breaking length of the paper, the number of double bends, the resistance to punching and tearing, as well as individual paper-forming properties, including the increase in the degree of grinding on the Schopper-Rigler scale. Grinding was carried out on a semi-industrial disk mill using a combined set with a wave-shaped inter-knife cavity with straight unidirectional knives.
