Estudo de caso: implantação de uma linha de britagem e moagem de calcário

Abstract

This work aims to present a case study of the development of an automation project for a limestone crushing and grinding plant. The development process will present the stages involved, from the design phase to startup. Initially, using AutoCAD software, a plant layoutwas developed, with a suggested ideal equipment arrangement flowchart. Next, a detailed list of inputs and outputs for all planned equipment and instrumentation was created, along with a list of sensors and actuators necessary for the project. A digital architecture was also developed, specifying the digital and analog cards for communication between field devices, as well as the Programmable Logic Controller (PLC). Interconnection diagrams were created, detailing communication connections, power supply for motors, inverters, soft-starters, and other equipment, ensuring complete system integration and the functionality of the industrial plant. Finally, the commissioning and start-up of the developed plant were carried out. The challenges faced throughout the project and the operational gains achieved after its completion will also be presented.
