Abstract
Pellets are produced in a mixing vessel. In this process, the material to be pelletized is passed through a propeller-like mixer with a helical centrifugal motion and sprayed with a finely nebulized wetting agent until pellets of the desired size have been formed. High yields of well-rounded pellets can be obtained in this way. The pellets can be coated for the purpose of controlled release of the active ingredient.

A process for the production of pellets, comprising passing the material to be pelletized through a mixer with an approximately helical centrifugal motion in an orbit in the direction of motion of the mixer in the mixing vessel and, by continuous or batchwise application of a finely nebulized wetting agent, which may contain a binder, to said material until the relative moisture content is at least 70%, measured in the stream of material, the agglomeration of said material is maintained until pellets with a diameter of 0.5 mm to 2.5 mm are obtained.
