Key words:
Pulpwood; debarking drum; debarking; mathematical model.		 Summary: The issues of the influence of the size of the drum, the frequency of its rotation, the degree of filling, wood species, length and diameter of the pulpwood’s on the process of debarking. Under the pulpwood in this paper refers round assortments intended for the production of semi-finished wood fiber in the pulp and paper industry. The main attention is paid to the resource in the process of cleaning the wood from the bark. The process of debarking in debarking drums is quite energy-and resource-intensive, which determines the existence of the problem of improving the process. Based on our review identified the key factors that characterize the parameters of raw materials and the mode of barking that can be traced to two factors: the number and strength of the impact given the pulpwood per unit of time. The separation efficiency of wood bark and wood raw material value of the losses determined by the intensity of interaction pulpwoods in the drum.
