Pellets made from titaniferous ores or their derivs. - in pelletising drum producing high strength pellets of uniform size

The plant consists of a drum rotating on a horizontal axis and divided into a row of compartments connected to each other and extending from a charging hole to a discharging hole. One compartment (I) is used for agglomeration and mixing of the charge, which then enters a spraying compartment (II) in...

Beschreibung
Zusammenfassung:	The plant consists of a drum rotating on a horizontal axis and divided into a row of compartments connected to each other and extending from a charging hole to a discharging hole. One compartment (I) is used for agglomeration and mixing of the charge, which then enters a spraying compartment (II) in which a binder is used to make pellets of a desired size. The pellets then level through >=4 compartments (III) employed to increase the mechanical strength and size of the pellets. Compartments (III) each possess the same length as compartment (II); but compartment (I) is 2-2.5 times the length of the other compartment so a dry charge can be fed into compartment (I). The ore derivs. include enriched slags obtd. by melting. Drum can also be used in the winning of refractory metals. L'invention concerne la métallurgie. Le dispositif faisant l'objet de l'invention est caractérisé en ce qu'il comporte au moins quatre compartiments de pelletisation 6, dont chacun a une longueur sensiblement égale à la longueur du compartiment d'arrosage 5, tandis que la longueur du compartiment d'agrégation est de 2 à 2,5 fois supérieure à la longueur de chacun d'eux, ce qui permet d'admettre dans le compartiment d'agrégation une charge sèche. L'invention permet d'obtenir des pellets de grosseur uniforme et à résistance mécanique accrue.
