Resumo(s)
Na presente dissertação concebe-se e projeta-se um moinho para a preparação de amostras
de minério destinado ao Departamento de Ciências da Terra da FCT NOVA. Avaliando as várias
possibilidades, opta-se pela conceção e pelo projeto de um moinho de martelos. Pretende-se que
o moinho processe um mínimo de 30 kg/hora e que reduza a granulometria do material de 70 mm
para 2 mm. O moinho é projetado para processar basalto por ser um material com um elevado
índice trabalho.
No dimensionamento do moinho consideram-se aspetos funcionais, de resistência e de
rigidez. Foram realizados modelos tridimensionais do moinho e também os desenhos técnicos,
nos quais foram considerados toleranciomentos.
In this dissertation, a mill is conceived and designed for the preparation of ore samples for the Department of Earth Sciences at FCT NOVA. Assessing the various possibilities, we opted for the conception and project of a hammer mill. It is intended that the mill processes a minimum of 30 kg/hour and that it reduces the particle size of the material from 70 mm to 2 mm. The mill is designed to process basalt as it is a material with a high labor index. When dimensioning the mill, functional, strength and rigidity aspects are considered. Threedimensional models of the mill were carried out, as well as technical drawings, in which tolerances were considered.
