Комплексный анализ операций переработки круглых лесоматериалов в технологическую щепу на целлюлозно-бумажном комбинате

Based on the analysis of ways of efficient use of resources in the preparation of round timber for processing on chips, a conclusion is drawn on the need for a comprehensive study of the cause of the formation of substandard chips. The quality of wood raw materials, the technology of its sorting and cross-cutting before feeding to debarking affect the volume of losses and the quality of wood chips. In this regard, it will be rational to sort timber according to its diameter, length, degree of mechanical and biological damage, and also preliminary sorting of logs, taking into account the distance between saws of the slasher, allowing to obtain balances of standard length. The use of a slasher to cut timber into balances inevitably leads to the formation of short pieces of logs. These segments with existing technologies can not be efficiently processed into technological chips. It is necessary either to install special lines for the processing of short pieces of logs, or at the stage of sawing long logs to exclude their formation. The structures of the transport equipment and the scoop drum need to be modified taking into account the large differences in the dimensional characteristics of the balances. The processes of grinding the balances and subsequent sorting of the obtained chips must be able to be adjusted taking into account the parameters of the processed raw materials. Chippers and chip screens of wood-preparation process require a structural refinement. The complex solution of these tasks will reduce the amount of wood waste, reduce energy costs, increase the level of resource saving at all stages of production.
