Multi-variate analysis of frictional interaction between grooved rollers and prepared sugarcane
Adam, Clayton J. & Loughran, Jeffrey G. (2004) Multi-variate analysis of frictional interaction between grooved rollers and prepared sugarcane. International Journal of the American Society of Agricultural and Biological Engineers, 47(5), pp. 1611-1618.
The Australian sugar industry utilizes rolling almost exclusively for extraction of sucrose from prepared sugarcane. The feeding and extraction performance of rolling mills is strongly dependent on the friction coefficient between counter-rotating rolls and the fibro-porous sugarcane blanket. Rolls are circumferentially grooved and roughened with weld droplets to assist juice drainage and maximize friction between rolls and blanket. Previous investigators have performed experimental measurements of the friction coefficient between metal surfaces and prepared cane or bagasse. This article develops a multi-variate empirical regression equation based on the experimental measurements of previous investigators to describe the dependence of the interfacial friction coefficient on normal pressure, groove angle, and relative rubbing speed. The friction coefficient was found to decrease exponentially with increasing normal pressure, decrease linearly with increasing rubbing speed, and increase with decreasing groove angle in accordance with simple wedge theory.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
