Development of Calibration Device for the Belt Weigher Based on the Material Superimposed Technology

Abstract:

Great accuracy is required in the settlement process of coal trade. In order to improve the accuracy of coal measurement, a set of online belt weigher calibration device based on the method of material superimposed has been developed. The mechanical structure of the whole device is well designed realizing material circulation conveying. At the same time the software and hardware of calibration system are fully designed.Finally the experimental results indicate that the uncertainty of the calibration device for belt weigher is within 2% and the minimum theoretical ratio of belt material superimposed is about 42% which attains the error requirement of grade 0.5.
