Before we dive into the case study, a little background information may be necessary. An iron ore pellet is a tiny iron ore ball (between 8 and 18mm of diameter) composed of pellet feed and iron ore fines, which are the finest forms of the iron ore, mixed with a flux (in Brazil usually limestone) and a thickener, which gives the pellets their consistency.
EXPONOR is an exhibition of global technology and innovation for the mining industry that takes place every two years in Antofagasta, Chile. A city located in a region at the heart of Chile's mining industry, which accounts for 54% of the country’s total metallic and non-metallic mineral production, including 16% of copper production.
The sugarcane industry is one of the most flourishing segments of the Brazilian Economy. With a production of up to 624 million metric tonnes of sugarcane in the 2017 harvest season, the country holds the world record production for both sugar and ethanol from this raw material. A broader view reveals that more than 37 million tonnes of sugar and 27 million cubic meters of ethanol were produced to meet national and expanding global demand.
Bulk material handling is an engineering field that is centered on designing and manufacturing of special equipment utilized to handle mainly dry materials such as ores, grains, sand, gravel and stone in loose bulk form. Mineral production, for instance, depends on a great quantity of bulk material handling equipment in order to move an impressive portion of the iron and copper ore productions in the world. In the following we want to explain how hydrodynamic couplings operate and how they can improve the MTTR of bulk material handling equipment drives.
