Abstract
As the Law for the Promotion of Utilization of Recyclable Resources was enforced with a view to resolving issues on resources and environment, various recycling plants have been operated. However, in the process of treating chips smashed for reproduction, repeated impingement of chips against blower's impellers and bends causes erosion, a serious problem. We make a report on erosion in recycling plants where wooden wastes can be reproduced into a particleboard, and on the influence of the impingement angle and velocity of chips upon erosion.
