Diseño y construcción de un molino de bolas planetario para el laboratorio de materiales de la Carrera de Ingeniería Mecánica

Abstract

This technical project was carried out due to the importance of implementing a planetary ball mill for the crushing of fine powders and at the same time obtaining steel chip spraying for the materials laboratory of the Faculty of Mechanical Engineering of the Technical University of Ambato The project is oriented in the design, construction, and functional tests that at the same time is composed of a two-phase motor, pulleys and a variable speed drive among other devices, for this, different types of mills were investigated. In the theoretical and analytical, the selection of a two-phase motor was made according to the needs of the planetary ball mill, the main elements were designed such as the structure which will support the transmission system and other components. In addition, the axes have the function of generating the planetary movement by means of pulleys. A fundamental aspect is the size, weight and noise with which the machine was designed. The main parts of the mill are: variator, motor, shafts, vessels, pulleys, timer and transmission bands, etc. The project was designed with the intention of using it for powder metallurgy applications, in which fine steel powders will be obtained in a range of 45 to 250 microns. In addition, it will facilitate research carried out by students, teachers and thus create new mechanical alloys. Finally, the machine was built with materials that are resistant to corrosion, are available in the market and have an affordable cost for their respective construction.
