ABSTRACT:
The dosage granulator comprises a feed hopper receiving reclaimed asphalt to be granulated. Under the lower opening of the feed hopper, a tearing up device is situated which is controlled by a conveyor type weigher mounted thereunder. The tearing up device comprises tearing rollers with knives, gratings, and a plurality of pressure arms reciprocating through the spaces of the gratings to press the material downwards. The tearing rollers rotate to drive the material towards the gratings, where it is cut by the knives in co-operation with said gratings. The dosage granulator may comprise a reciprocating stirrer situated between the tearing rollers. Reclaimed asphalt of a size of up to 30 cm may thereby be cut into granules of 5 cm. The amount of granulated material is adjusted by means of the conveyor tape weigher.
