Diseño y simulación de una zaranda mecánica oscilatoria con una capacidad 50 kg/min de arena

Abstract

In the present project we looked for the best option for the design of an oscillatory mechanical zaranda that can sift an amount of 50 Kg / min of sand. Brief explanations were given about the history of the zaranda, operation, classification, types of movements, applications and basic concepts of the aggregate. The most suitable option was selected among three possible designs for the machine, with the help of an assessment of established parameters that allowed to observe the best option of zaranda to adapt to the working conditions that are needed. Following the design, the recommended materials for the structure and elements of the machine were chosen, being STEEL ASTM A-36 and AISI 1018. The dimensions of each of them were established with recommendations of mechanical design and material strength. Through the use of simulation with the help of specialized software (Solidworks 2017) it was verified that the most critical elements resisted the applied loads and it was possible to observe the deformations that each one presented, verifying that the design and material selected was the correct one. As a final part, an economic analysis was carried out obtaining a total value for the construction of the zaranda and compared with a similar machine that is offered in the market.
