Abstract(s)
Numa instalação de britagem, o processo de fragmentação consiste em reduzir os materiais rochosos em fragmentos de menor dimensão, através dos fragmentadores, originando lotes comercializáveis com diferentes granulometrias. Neste sentido, é possível obter a curva granulométrica para cada lote, através do ensaio de granulometria. Todavia, existe um software que permite obter esta curva granulométrica e o consumo energético, a partir dos equipamentos que existem na instalação, ou seja, o simulador “Bruno”. Para verificar se o simulador “Bruno” é fidedigno, consideraram‐se os valores obtidos através deste, tendo como linha de comparação os valores dos ensaios de laboratório sobre materiais obtidos na instalação de britagem em estudo e os dados fornecidos pela empresa ElevoAgregados, proprietária da referida instalação. Assim, numa fase inicial foram abordados todos os temas necessários à instalação de britagem, aos ensaios laboratoriais e ao simulador “Bruno”. Foram analisadas amostras da Pedreira de Fornelo e, após o tratamento de todos os dados, realizou‐se uma comparação entre os dados obtidos na simulação e os dados reais, ou seja, na instalação atualmente em funcionamento e sobre a qual recaiu este estudo. Perante os resultados obtidos, concluiu‐se que o simulador” Bruno” é uma ferramenta importante e com elevado potencial, na fase de projeto ou como instrumento de controle de uma instalação em funcionamento e que pode ser utilizado, seja para obter as curvas granulométricas, as produções ou até mesmo para o cálculo do consumo energético.
In a crushing plant, the fragmentation process involves reducing rocky materials into smaller particles through shredders, creating batches with different particle sizes. In this sense, obtaining the particle size curve for each batch through the particle size test is possible. However, the software allows obtaining this granulometric curve and the energy consumption from the equipment that exists in the installation, that is, the “Bruno” simulator. In order to verify if the “Bruno” simulator is trustworthy, we will take into account the values obtained through it, having as a line of comparison the values of the laboratory tests and the data provided by the company ElevoAgregados. Therefore, in the initial phase, all topics necessary for crushing installation, laboratory tests and the “Bruno” simulator were addressed. Samples from the Fornelo Quarry were analyzed, and after processing all the data, a comparison was made between the data obtained in the simulation and the real data, that is, in the installation currently in operation and on which this study was carried out. The results concluded that the simulator “Bruno” is reliable and can be used to obtain particle size curves, productions or even to calculate energy consumption.
