    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 planetario 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, 2019) Maldonado Bernabé, Christian Patricio; Amores Balseca, Edwin Gustavo; López Villacís, Gonzalo Eduardo
    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.

    Diseño y construcción de un molino de bolas tipo Attritor con un sistema de refrigeración para aplicaciones de pulvimetalurgia para los laboratorios de la Carrera de Ingeniería Mecánica de la Facultad de Ingeniería Civil y Mecánica de la Universidad Técnica de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Saquinga Chicaiza, Stalin Wladimir; Chiluiza Chicaiza, Flavio Eduardo; Peña Jordán, Francisco Agustín
    This Technical Titling Project focuses on the design, construction and operation testing of an attritor-type ball mill for obtaining powders and alloys from metal chips, acquiring information about the process of powder metallurgy, data and characteristics of the material and using, selection weights of alternatives, criteria such as design and calculation corresponding to the most relevant parts of the milling. As a basis is the analysis of the grinding parameters with the attritor mill should be recorded, such as the turning speed, contamination of the powders due to the material, temperature control and grinding time. Continuing with the selection and weighting of the operating systems in the machine being valued according to weighting criteria such as reliability, maintainability, assembly and price of each of the alternatives to subsequently be calculated valued with its reliability factor. Finally, we proceed to the construction and assemble of parts and elements of the machine being these built and others acquired. One of the most relevant the frequency inverter because it regulates the turning speed and prevents the engine from suffering damage in case of jams and then goes through the operating tests, obtaining the expected results in the mechanical grinding.

    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.
