    Diseño y construcción de un molino de bolas de alta energía con sistema de refrigeración para aplicación de pulvimetalurgia para el Laboratorio de Materiales de la Carrera de Ingeniería Mecánica
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2020-10) Moya Campaña, Alex Abraham; Saquinga Sangucho, Edwin Vinicio; López Villacís, Gonzalo Eduardo
    This technical project was carried out due to the importance of implementing a high-energy ball mill for powder metallurgy application and in turn obtaining metal powders for the materials laboratory of the Faculty of Mechanical Engineering of the Technical University of Ambato. The project is directed at the design, construction, and operation tests, which are made up of a biphasic motor, eccentric, axles, gear wheels, tensioners, structural system components, for which the theoretical and practical part was investigated, with a grinding mechanism composed of a grinding base box, box lid, grinding tray and demolition elements, defining its support, where the axes have the function of generating movement through the gear wheels and the synchronous belt; where the size, weight and noise of the mill are very important parameters to design as well as the maximum volume of material to be ground; Thus defined its purpose of construction obtaining particle sizes of 0.30 to 4.72 mm, in a time that varies from 0 to 120 minutes. Finally, the machine was built with materials available on the market at affordable prices in case any change or maintenance is required.

    Diseño y construcción de un molino de bolas para aplicaciones de pulvimetalurgia en los Laboratorios de Ingeniería Mecánica de la Facultad de Ingeniería Civil y Mecánica de la Universidad Técnica de Ambato

    The ball mill is designed to help obtain new mechanical alloys, the design part of the amount by weight of material to be ground which is 2 kg. The ball mill has a stainless steel drum, the dimensions are 21 cm diameter and 34 cm in length ideal to withstand high grinding temperatures, it is also designed under milling parameters such as the critical speed at which the mill must operate, the actual power to be generated by the mill, is capable of supporting up to 18 kg which are decomposed into material to be ground, 8 kilograms by weight of the grinding bodies and 8 kilograms in wet milling, the support capacity of the drum is determined by software of fine elements, this type of mills is indispensable the calculation of the system of cascade, so that in the construction of the mill was added 4 interior grids that facilitates the obtaining of the metallic powder. In order to maintain the critical speed of 74 rpm, the transmission ratio in which the required gear unit and chain drive system is determined is calculated. The ball mill according to the distribution of the balls can obtain a size of 20 um of grain, which makes it ideal for making new mechanical alloys.
