Follow-up study of Evolution-drum chipper; Evolution-energiapuuhakkurin kaeyttoeselvitys

Abstract

The aim of this project was to test and further develop a new type of a drum chipper. It was assumed that this Evolution-chipper would be able to produce fuel chips without long splinters and would also be reliable and effective in chipping work at road-side landings. In this project the fuel chip quality and productivity of the chipper were found out. The follow-up study started in October 1995 and ended in the end of 1996. According to the follow-up study the mechanical availability of the chipper was 83 % during a period of one year. Because of the rather low level of fuel chip utilisation in Finland the work sites are located far from each other. Therefore the moving between working sites take as much as 1/5 of the total working hours. The chipper is easy to operate and the differences in the productivity between operators are modest. The chipping productivity varies mainly depending on the raw material. The average productivity was 45,8 m{sup 3} (loose) per gross effective hour during the follow-up period. The internal screening system of the chipper diminishes the amount of long splinters effectively. Other chipping parameters (such as rotating speed) affected the chip quality  More>>
