Abstract

Traditional logging residue purchase methods have based either on chipping at the lot or in the roadside storages. However, methods have been developed also for long-distance transportation of complete logging residues. In this case chipping would be carried out at the power plant. New methods, based on on-site chipping, are being developed for purchase of logging residues. The bundling equipment used in these purchase chains has been developed in Sweden. The purchase chains under development would enable the forest haulage and long-distance transportation of logging residues by present forest and long-distance transportation equipment, and it would ease the storage of logging residues. The objective of the project was to develop, on the basis of the idea of Biowatti Oy, a continuously operating logging residue bundling device. Because the success of compaction is the critical factor effecting on the operation of the equipment, the project was carried out in two stages. The objective of the first stage, presented in this report, was to develop, construct and test the compaction method. Several modifications were made to the device during the research. New tests were carried out after the modifications in order to determine the operation of the equipment, the compactness of the bundles, and determination of the further development required. The final version of the device was equipped with a feeding table in which the feeding of logging residues occurred by the aid of a lamellar chain track, equipped with shear keys, and with a pressing roller. Test runs showed that by using the continuous compression method, developed in the project, it possible to obtain the compression target (45 %). The capacity of the bundler could not be tested properly because the test runs were relatively short. The power demand and capacity measurements of the bundler will be carried out wider in the second part of the project, as soon as the compression equipment has been developed further. On the basis of the preliminary experiences, the weak point of the delivery chain of bundling has been e.g. the high investment costs of the bundler, and relatively low productivity of the device compared to investments. However, the project created a new solution, by which it is possible to improve the competitiveness of the purchase chain and hence to promote the development of a new purchase method for logging residues, supporting the methods already in use in Finland.
