Abstract (en)

[origin: EP1504865A2] To soak loose materials with a bonding agent, they are dried to a residual moisture content level of 3-20% and transferred to a conveyor channel (4). They are carried in a heated air stream to the wetting station (7), where a preceding section (8) with a reduced cross section accelerates the flow speed directly in front of it. At the wetting station, the bonding agent is delivered by jets (9), and the saturated material is passed through a dwell section (10), before passing into a conveyor channel (13) using a heated carrier gas giving final drying.
