THE EV ALUA TION METHOD OF THE STABILITY AND ACCURACY OF A QUANTITATIVE WEIGHING SYSTEM OF COMBINED MATERIAL IN PRODUCING SYSTEM OF COMBINED MATERIAL IN PRODUCING BUILDING MATERIAL

Abstract

The application of weighing system of combined material in the production line of building material requies the evaluation of the stability and accuracy of these systems. The article presents the experimental and process out-of data method of the weighing results in order toevaluate the the stability and accuracy of the weighing system of combined material in theproduction of building material. The weighing results obtained on 100 samples have shown thatthe tested weighing system has probability of weighing values is 98,85% with average differenceof weighing values against the center of distribution being 0,94 kg and accuracy being 1.5%.These values have proved that the tested weighing system has small dispersion of weighingvalues, high stability and accuracy, thus fully meeting the requirements for a weighing system ofbuilding material. In fact, this weighing system have been put in use in several cement plants thestability and accuracy of which have been certified as in accordance with the publicized ones
