Analysis of Belt Weigher Accuracy Limiting Factors

摘要

In practical experience, the accuracy of coal mass flow measurement by the use of belt weigher is considerably lower than the theoretical, as the result of a number of limiting factors. The analyses that have been designed and the practical experience point to the problems occurring in the installation, maintenance, and testing of belt weighers. The weigher measurement accuracy, however, is mostly determined by the real conditions of use. This article presents a model of all the disturbing effects on the belt weigher measurement system, as the result of a systematic analysis of their influence. A few of adaptive methods for the compensation of these influences are listed together with the directions for further development.View full textDownload full textKeywordsAccuracy, Belt weigher, Coal, Compensation, Mass flow rate, Total massRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/19392699.2011.552896
