Diseño y construcción de un molino de impacto para un sistema mecánico de desintegración de diatomita con un requerimiento de 10T/día en malla 325

Abstract

The main objective of this research work was the design and construction of a new impact mill for the disintegration of diatomite ore in 325 mesh, which will be adapted to a current system that does not meet the requirements demanded by the new needs of the interested company. Initially, an analysis of the operating parameters of the calcium oxide grinding system available in the company was carried out, on the other hand, certain necessary characteristics were received in the new design. With the dimensioning of the elements obtained in the mechanical design and the selection of others necessary for the mill, we model it in the SolidWorks software for a pre-visualization of the equipment and a quick obtaining of the plans for the construction, the SAP2000 software we use it for the design of the structure, and the ANSYS software for the simulation of the impact of the diatomite particles in the different disintegration zones and the verification of resistance of the elements subjected to stress. The construction was carried out in a mechanical workshop that had all the facilities for machining parts with a high degree of quality and experience on the part of the personnel. An impact mill with a vertical axis and three disintegration zones was obtained, the power is 30 hp at a speed of 1750 rpm, which will meet the requirements demanded by the company, in addition to having the ability to pulverize or disintegrate minerals a slightly less soft, which was adapted to the milling system that the factory has. It is recommended that the diatomite ore entering the mill be properly calcined and free of other impurities or particles that may cause internal damage.
