Wood is of great practical importance as a starting material for the recovery of cellulose. Wood plays not only an important economic role as a building and finishing material, but is also one of the cheapest and most widely used raw materials for the industrial production of cellulose vines. In turn, the grinding equipment serves to divide the cellulosic materials into fibers, from the grinding of the fibers and imparting certain properties to them. One of the most important properties of paper is mechanical strength. The standard provides for certain requirements for different types of paper, depending on the consumer conditions for the use of finished products. Durability of paper is determined by various indicators characterizing: paper resistance to a gap, breakdown, tear, an anguish, lengthening to a gap. In this work, the role of milling of fibrous materials in the general preparatory cycle of pulp and paper production is considered, the advantages of knife-free milling are presented, the factors determining the strength of paper are considered, functional dependencies of the main physical and mechanical characteristics of the finished product on the complex parameter of the quality of pulp milling and the complex parameter of the machine are obtained. Numerical value of complex parameter of grinding quality is determined depending on duration of grinding.
