Diseño y construcción de un molino de martillos para la molienda de granos secos y hojas para té

Abstract

The study of the analyzed microenterprise does not have a design and construction plan for hammer mills, so they made empirical designs, where a very high capital investment was made compared to Other competitions, obtaining a minimum profit. The present curricular integration work had as its objective to design and build a hammer mill for grinding dry grains and tea leaves, to optimize economic resources and have a high percentage of emciency of functionality. The methodology implemented was to perform a competitiveness analysis with existing models in the market to obtain the design parameters through the QFD, for the best construction and assembly alternative, an analysis was carried out using a morphological matrix based on the requirements of the selected microenterprise, obtaining a hammer mill with twenty-four hammers and seven discs driven by a 5Hp single-phase electric motor. For the detailed design Of the grinding chamber components, it was carried out based on equations existing in machine element design books. In the hopper, frame and support base, computer-aided engineering (CAE) was applied using ANSYS Workbench 2021 R2 software for the design. By implementing finite elements, it was possible to validate all the mechanical components, guaranteeing adequate safety factors in the working conditions of each mechanical component- The hammer mill was built and assembled and evaluated using a performance testing methodology for grinding dry grains and tea leaves. It was concluded that the hammer mill reduced costs and manufacturing times, guaranteeing the design parameters and obtaining an adequate percentage of efficiency
