FIELD: mixing.
SUBSTANCE: present invention relates to a tool for dry mixing and coating of powder mixtures. Tool (1) for dry mixing and coating of powder mixtures comprises fastening rod (2) and disk-shaped element (4) with diameter d fixed on it with upper surface, lower surface and connecting upper and lower surfaces with circumferential surface, wherein disc-shaped element (4) has grooves extending parallel to the axis of the rod, wherein each groove has two grooves of wall (9, 10) extending from the circumferential surface to bottom (7), wherein tooth (5) is formed between two grooves, wherein disc-shaped element (4) has a main part and at least one wear-resistant element (6, 6') attached to the main part, wherein at least one section of each groove wall (9, 10) adjoining the circumferential surface is formed by said at least one wear-resistant element (6, 6'), note here that bottom surface has at least one swirler (8, 8') extending above bottom surface, note here that swirler (8, 8') is located closer to fastening rod (2) than groove bottom (7).
EFFECT: creation of a contamination-free tool suitable for dry mixing, dry dispersion and coating of powder mixtures.
