A method for producing a laundry product comprising generally spherical beads formed from particles of soap, synthetic detergent, or the like. In the method of this invention, the particles are formed into an annular fluidized bed of particles and gas in a rotatable chamber as a result of relative high speed rotation of the chamber and continuous introduction of gas into the rotating chamber. Periodically the particles are tumbled in the chamber by abruptly reducing the rotational speed of the chamber. The particles may be treated in the chamber by the introduction of fluids onto the particles in the rotating chamber.
