The invention provides a method for the production of a zeolite particle composition which has optimized characteristics, such as enhanced adsorption and specific ion exchange properties. A method and an apparatus for producing improved zeolite particle compositions are provided, where the particles are treated with an oxygen-containing gas during micronisation. The zeolite particle compositions can be used in a method for treatment of the human or animal body by therapy and/or prophylaxis, and specifically in a method of treating or preventing conditions of the human or animal body or symptoms of these conditions that are related to heavy metals, endotoxins, exotoxins, and/or bacterial, viral or parasitic intoxications in or of the digestive system, mucosal surfaces or the skin. Also, new zeolite particle compositions can be used as food additive, as filter for purification of water, in packaging materials, or as cosmetic ingredient.

Apparatus (10; 110) for the micronization of a powdered material or product (P) comprising a micronizer mill (20), of the type with high-energy jets of a gaseous fluid, in turn comprising a micronization chamber (20a), in which micronization chamber the powdered material (P) is micronized as a result of the collisions between its particles caused by the high-energy jets (G) of a first gaseous fluid (A), such as nitrogen or air, wherein the micronization chamber (20a) of the micronizer mill (20) is delimited by walls (20f) which have at least one porous portion which is traversed by a regular flow (f1), of a second gaseous fluid (F), aimed towards the interior of the micronization chamber, so as to avoid the formation of incrustations and/or accumulations of powdered material in the same micronization chamber (20a). More particularly the micronization apparatus (10) comprises a first outer annular chamber (20b) which extends around the micronization chamber (20a) and is fed by the first gaseous fluid (A) which generates the high-energy jets in the micronization chamber, and a second intermediate annular chamber (20d) which is associated with the porous wall (20f) which delimits the micronization chamber (20a) and is fed by the second gaseous fluid (F) aimed to flow through this porous wall, or, in a variant (110) of the micronization apparatus, comprises instead of the first annular chamber a system of channels (120b) which convey the first gaseous fluid which generates the high-pressure jets and extend through the annular chamber (120d) fed by the second gaseous fluid (F) which traverses the porous wall. Advantageously the apparatus of the invention (10; 110), avoiding the formation of incrustations and similar accumulations inside the micronization chamber (20a) of the micronization mill (20) and in the adjacent areas, improves the efficiency of the micronization process and the quality of the micronized end product and moreover considerably reduces the costs of maintenance with respect to conventional micronization mills and apparatuses, with high-energy jets of a gaseous fluid.

Various wear resistance designs may be applied to a reactor configured to facilitate chemical reactions, and/or comminution using shockwaves created in a supersonic gaseous vortex. The reactor may include a rigid chamber having a substantially circular cross-section. A first gas inlet may be configured to introduce a high-velocity gas stream into the chamber. A first replaceable wear part may be disposed in the chamber to absorb wear impact caused by the gas stream. In some implementations, the first replaceable wear part may be a cylindrical rod continuously fed into the chamber. In some implementations, the first replaceable wear part may be coated with, or composed of, a catalytic material, and/or may be electrically isolated from the rest of the reactor. In some implementations, a second gas inlet may be disposed to steer the gas stream to a desired area within the chamber to even out the wear impact.
