Device and method for mixing, in particular dispersing

A device for mixing comprising:

• a housing with at least one inlet,
• a first process region for mixing and in particular dispersing supplied materials, and the materials are introduced into the first process region through the at least one inlet,
• a second process region for diverting the mixture to an outlet,
• a first gap forming element which is assigned to the first process region and comprises openings,
• a second gap forming element which is assigned to the second process region and corresponds with the first gap forming element, and the second gap forming element comprises openings,
• wherein at least one of the gap forming elements is designed so as to be rotatable about an axis of rotation relative to the other gap forming element,
• the openings of the first gap forming element and the openings of the second gap forming element are arranged in such a manner that the openings do not overlap and a mixture, produced from the supplied materials, is conductible from the first process region into the second process region through the openings in the two gap forming elements such that the mixture only passes from the openings of the first gap forming element to the openings of the second gap forming element through a gap between the openings.

A method for dispersing materials in a device comprising the steps

• introducing at least two materials, preferably a solid and a liquid, into a first process region of a device,
• mixing the at least two materials in the first process region to form a mixture,
• conducting the mixture through a gap which is formed between a first gap forming element and a second gap forming element,
• wherein the gap forming elements comprise openings, said openings do not overlap, and the two gap forming elements move relative to each other, and the mixture is conducted from the first process region into a second process region through the gap and the openings such that the mixture only passes from the openings of the first gap forming element to the openings of the second gap forming element through a gap between the openings.
