Desenvolvimento dum sistema de controlo e supervisão de balanças doseadoras de correia, aplicável a moagem de cimento (Cimentos de Moçambique – Fabrica da Matola 1)

Abstract

The main focus of this work is the development of a control and supervision system for the dosing scales at Cement Mill 7 (Fábrica da Matola 1), with the aim of improving their operation in terms of stability and performance, compared to the current situation. Mention is made of the application of real-time monitoring instruments across the entire platform, in order to ensure that the material flow process is constant and with minimal intermittency. The PLC programming logic is described in terms of information management during the material dosing process, as well as serving as a means of communicating with supervision about the current status and warning of alarms in the event of any anomalies. In addition, the work illustrates the characterization of occupational risks, as well as the impacts with the system in operation.
