Abstract
Method and apparatus for the recovery of the solid material content of solutions and/or suspensions as granules in a gas fluidized bed which contains particles, the composition of which is identical with that of the solid material in the solution and/or suspension to be processed, in which fluidized bed the solution and/or suspension is sprayed onto the surface and/or interior of the hot gas, especially hot air fluidized layer, and from which fluidized bed particulate material is continuously withdrawn at a mass flow rate corresponding to the solid material content of the liquid phase sprayed in, and also, in which system a grinding mechanical effect is created by forcing continuously particles formed in the fluidized bed through at least one slit of controllable clearance, located in the fluidized layer, itself, in order to produce in a single technological step, in a single apparatus particulate material of predetermined, given particle size distribution. The apparatus disclosed in the present invention has, inside the fluidized bed, in the fluidized layer itself, a slit-forming device consisting of free rolling rollers and a grinding surface, said rollers advantageously being periodically rotated with respect to the grinding surface.
