Regarding a complete fine coal briquetting line, fine coal and binder from the tank was passed to the screw mixer. The mixtures was transported to the central tank, where the screw conveyor fed the roller press. Separated briquettes were transported by a drying conveyor to the drying chamber. Any separated fines were recycled by reverse conveyor to the stacker of the briquetting unit. Dried and cooled briquettes were transported by container or big-bag. Axisymmetric, flattened, barrel-shaped briquettes were obtained. The briquettes were then dried and cured.
