Outotec is the world's leading supplier of Grate Kiln pellet plants, with more than 50 installations globally totaling over 130 mtpa of production. The Outotec technology produces superior-quality pellets while minimizing overall plant operational expenses.
This is shown by critically examining the dust generation of pellets from several facilities. The dustiness of pellets is associated with overall pellet strength, and is an important quality measure of fired pellets on its own. A clear distinction between the dustiness of grate-kiln and straight-grate fired pellets is established.
