Abstract: . The paper analyzes the actual volumes of the raw material base of the timber industry complex in the Krasnoyarsk Territory. An assessment is given to the types and amounts of generated logging waste. An innovative technology and equipment for the processing of logging waste in the conditions of logging into wood flour is proposed. The analysis of the design features of the mobile grinding plant has been carried out. An assessment of the efficiency of processing felling residues directly at the cutting area i… Show more

To date, it is possible to produce a large number of variants of finished wood products. At the same time, each type of product requires its own production process, raw materials and different costs. The cost of the products will also vary. In addition to the above, a large number of parameters affect the portfolio of marketable products being formed. They have different degrees of influence, which makes it difficult to form a list of effective products. The purpose of these studies was to conduct a factor analysis of the formation of a portfolio of commercial logging products. The method of factor analysis and expert assessments was applied to the research. To conduct a factor analysis, 14 factors were identified in three groups (technical and technological, raw materials, economic and legislative). To assess the influence of factors on the choice of a portfolio of marketable products, experienced employees of the engineering and technical direction of logging enterprises were invited. According to the calculations carried out in the framework of the research, the opinions of experts are consistent. According to the research results, the demand for products; the market price of products; defects of raw materials (9%), as well as the required level of personnel qualification; the cost of production; the cost of raw materials and the purchasing power of the population (8%) have the greatest influence on the choice of a portfolio of marketable products to maximize the use of raw materials. The obtained data is planned to be used to compile mathematical models and form rational technological chains of the logging process for natural, climatic and production conditions.

The paper presents the test results of the universal woody green separator “Sibirika 21”, which uses a replaceable knife and brush type drum as a working element. The separator was tested at an active clearcutting area of mature and overmature stands at the following coordinates: By. region, Krapivinsky district, Krapivinsky forestry, Ivanovskoye tract, block No. 16, section No. 17. During testing, it was found that for deciduous trees it is preferable to use a brush drum. In this case, for example, for birch, it was possible to obtain woody greens with 100% purity. As a brush material, it is preferable to use twisted nylon fibers with a square cross-section and a side of 3 mm. When harvesting coniferous foot, the best productivity (up to 600 kg person/hour) and cleanliness (82%) is ensured when using a knife drum.
