Process and device for introducing additive materials in a receptacle at the area of highest pressure

A method for feeding non-dry particulate, additives or coating stuffs to a material, the method comprising:

• providing a receptacle having a lateral wall;
• charging the receptacle with the material to a charging level;
• providing at least one mixing tool of a predetermined shape within the receptacle;
• rotating the mixing tool at a rotational speed wherein the speed and shape of the mixing tool moves or rotates the material in the receptacle thereby generating a region on the lateral wall at which the moving or rotating material exerts a highest pressure;
• providing the receptacle with at least one feeding device located on the lateral wall at the region of highest pressure;
• feeding the non-dry particulate, additives or coating stuffs into the receptacle at the region of highest pressure to uniformly disperse the non-dry particulate, additives or coating stuffs into the material within the receptacle to produce a final product.
