    Desarrollo de un plan de mantenimiento preventivo para el área de molienda de la empresa Molinos Miraflores S.A de la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-09) Ortiz Cañar, Giovanni Paúl; Christian Byron, Castro Miniguano
    The accelerated development of the industry and the high demand for products in less time have allowed the increase in the use of machinery and equipment, the same as representing an investment, require maintenance processes, in order to extend their useful life and guarantee its availability within the production line. For this reason, this technical document is developed, focused on mitigating the maintenance needs required by the machines that make up the grinding área of the Miraflores mills located in the city of Ambato, in order to carry out this study A bibliographic analysis was used together with a field study that allows us to determine both the mechanical and electrical components that make up the machines, all this in order to establish the elements that are highly prone to failure or causing them in a certain period of time. weather. Keywords: Maintenance preventive, Mills, Grinding, Miraflores, Matrix, FMEA, criticality, NTP, log, Maintenance range. Using both AMFE and criticality for the failure analysis, allowing the development of the logs and the maintenance ranges based on the concepts supported within the NTP 679, which detail and delimit the failure modes and the effects that the elements have within them. the processes used in order to identify and analyze possible failures.

    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 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.
