摘要：Apparatus for wetting discrete particles of dry powder material such as polyelectrolites, carbon and other hard to wet material, is disclosed in this application. The apparatus comprises a wetting tank which is porvided with liquid supply and discharge mechanisms and a rotary drum which is only partially immersed in the liquid contained in the wetting tank. As the drum rotates it carries a thin layer of liquid on the surface portions not immersed in the liquid and also agitates the liquid in the tank. The powder is carried in a feeding hopper and discrete particles are discharged to the layer of liquid carried by the drum and thereafter the individually wetted particles are discharged into the liquid in the wetting tank where it starts to form a solution. The solution flows through the discharge mechanism and into a separate aging tank where the solution is finally formed. In one preferred embodiment of the invention a special spreader nozzle is used to spread the particles along a straight line on the drum.
