ABSTRACT:
The subject invention relates to method for briquetting fines and ultrafines comprising mixing the fines and ultrafines on a continuous basis with a binder system having low viscosity of up to about 200 cps and at least 50% solids, such that the resulting briquette contains less than about 3% binder by weight of the briquette.
The invention further relates to a process for producing briquettes from fines and/or pretreated ultrafines comprising discharging the fines and/or pretreated ultrafines into a high speed mixer; discharging the components of a binder system into the high speed mixer through fog nozzles simultaneously with the discharge of the fines and/or pretreated ultrafines; agitating the binder and the material to produce a homogeneous binder-fines-ultrafines mixture; discharging the homogeneous binder-fines-ultrafines mixture into a delay box for a period of time such that the mixture is at the point of incipient cure; discharging the mixture at the point of incipient cure into a briquetting press and forming briquettes therefrom; discharging the briquettes onto a heated conveyor for a period of not longer than 4 minutes to cure the briquettes, and collecting the cured briquettes.
