Diseño y construcción de una máquina pulverizadora para el laboratorio de procesos industriales de la ESPOCH

Abstract

The aim of this work is to design and build a grinding machine to complement a flour production line in the industrial processes laboratory that is optimally functional. The present work began with a complete bibliographic review of the elaboration of equipment previous the determining the most important characteristics of the mills, information of the environment was collected to determine through weighted criteria the most suitable alternatives of the mill to facilitate the size reduction of the particles to be studied. The characterization of the raw material was carried out based on the INEN standards of each one of them in order to understand their characteristics for the design of the pulverizing machine and to present the equations that will allow us to design each one of the assigned components, which are the following: the feeding system, the crushing system and the discharge system having as a result of the fundamental elements of the machine a motor of 1 HP, pins of 82 mm by ¼ in, a rotating and static disc of 180 mm, the shaft of 206.88 mm by 1 ¼ in, hopper separator of 57 mm, feeding hopper of 208.59 mm - 210.14mm and a support which has a dimension of 306.35 mm wide by 572.7 mm long and 500 mm high. The equipment built resulted in a product which is appropriate to the conditions of the proposed flours, having positive efficiencies and the product obtained complies with the conditions given in the corresponding INEN standards of the flour, besides having additional functions which will help with the practical knowledge of the students of the career.
