Abstract:
The invention relates to granulating solid products, in particular mineral fertilisers using liquid and solid initial products. The inventive drum granulator comprises a main drum provided with a transport attachment embodied in the form of distribution blades which are arranged in several ranges on the internal surface thereof and in form of retaining blades which are arranged prior to said distribution blades and a retaining ring on the output end of the drum. Said drum granulator also comprises an additional external drum, a reverse conveyor worm which is arranged between the drums and rotates therewith, a product loading chamber embodied in the form of an external ring provided with receiving-transporting blades which are arranged oppositely with respect to the reception windows of the main drum, conveying chutes arranged after each reception window, a screw conveyor placed between the loading chamber and the retaining blades, a product unloading chamber, a device for returning a fine fraction to the main drum disposed in the annular space between drums after the reverse conveyor worm, a nozzle and a loading tube mounted on the fixed part of the loading chamber. The main drum comprises a classifier connected to two drums and a classifier cleaner fixed to the wall of the unloading chamber. The device for returning the fine fraction is embodied in the form of radial receiving-distributing-transporting blades which pass through the reception windows to the main drum and is disposed between the retaining and distribution blades. Said invention makes it possible to ensure a uniform circulation of the fine fraction and the mixing of components.
