Removal Of Eucalyptus Vessel Segments Using Centrifugal Cleaners, Amnuay Ponpued
Removal Of Eucalyptus Vessel Segments Using Centrifugal Cleaners, Amnuay Ponpued
Masters Theses
Two commercial feedforward centrifugal cleaners were used in the study of vessel segment removal from bleached eucalyptus pulp. The reduction of vessel elements yielded a reduction of vessel pick tendency and other problems caused by vessel elements which limit the use of eucalyptus pulp in paper stock furnishes. The operating conditions of the centrifugal cleaners were evaluated for their effect on separation efficiency. Pulp loss with rejects was reduced by multiple stage separation. The Vandercook Proof Press was used to compare the picking of cleaned, original pulp and two higher-vessel-content pulps. Regression analysis and ANOVA showed significant effects of feed …
Improving Maintenance Effectiveness, Stephen J. Thierry
Improving Maintenance Effectiveness, Stephen J. Thierry
Masters Theses
A methodology is advanced for measuring the productivity of industrial maintenance operations. A work sampling study and a production to maintenance interface survey are conducted to identify the current level of maintenance effectiveness at a food processing plant. Variables affecting maintenance effectiveness are postulated from site observations of the plant maintenance operation. A total of nine changes are proposed; three are implemented as part of this study and six remaining changes are proposed for the future. All recommendations are targeted at increasing the overall effectiveness of the maintenance operation under study.
