Abstract

Through this work, it is proposed to develop a computer program destined to follow the wear and tear of parts of a mill, with the objective of obtaining the parameters of the variables that have a direct inffluence on the process. Thus, there will be a starting point for the development of a multi-functional program, formulated with a base from a dynamic database from field and laboratory results, past and present, which allow the parts manufacturer to follow up the performance of his products, making possible their improvement, aiming to obtain the best cost/benefit relationship. The losses from wear and tear in the mineral industry are considerable, so much so that, for example, the refitting of the mills may represent up to 20 per cent of the cost of milling. This demonstrates the importance that must be given to the metallic consumption in milling, either in the search for better designs and materials or as well in the increase of the availability of the equipment. The forms of the worn out pieces vary as a function of their specific application - and even then, identical pieces, working side by side with the same mineral, may require different types or forms of design. Diverse methods have been developed to follow up the wear and tear of mill linings, among them that of control by the physical mapping by ultrasound and control by calibration. (AU)
