Diseño y construcción de una trituradora de arena de moldeo para el área de fundición de la empresa MINABRADEC.

Abstract

The objective of this investigation was the design and construction of a sand molding crusher for the foundry area of the MINABRADEC company. This investigation arises due to the inefficiency of the crushing process in the company, which was done manually, so it seeks to solve this problem. For that it was necessary to investigate bibliography and technological proposals related to the different existing crushing methods, following with the conceptual design of the product, were the needs of the client and specifications of the machine were established, giving in this way different alternatives of solution to proceed to select the most appropriate, according to the results that were obtained in the study of the house, of quality and weighted criteria was selected a hammer crusher. The selected machine was modeled in the software SolidWorks to confirm its dimensions and continue with the mechanical design of each one of its elements, thus determining diameters, dimensions and safety factors of the same, then the impact simulation of the crushing process was performed in the ANSYS software checking the calculation made. A hammer crusher was obtained which crushing system consists of a main axis, 4 secondary axis each with 10 hammers and a working capacity corresponding to 25,19kg/min, delivering a final product with a granulometry of 230 to 300 microns suitable for the smelting process of the company. It is recommended that the sand entering the machine does not have traces of molten material, so as not to prematurely wear out the system and not to clog or block the elements of the machine.
