A static spray mixer for the mixing and spraying of at least two flowable components is proposed having a tubular mixer housing (2) which extends in the direction of a longitudinal axis (A) up to a distal end (21) which has an outlet opening (22) for the components, having at least one mixing element (3) arranged in the mixer housing (2) for the mixing of the components as well as having an atomization sleeve (4) which has an inner surface which surrounds the mixer housing (2) in its end region, wherein the atomization sleeve (4) has an inlet channel (41) for a pressurized atomization medium, wherein a plurality of grooves (5) are provided in the outer surface of the mixer housing (2) or in the inner surface of the atomization sleeve (4) which respectively extend toward the distal end and which form separate flow channels (51) between the atomization sleeve (4) and the mixer housing (2) through which the atomization medium can flow from the inlet channel (41) of the atomization sleeve (4) to the distal end (21) of the mixer housing (2). Each flow channel has a respective changing inclination toward the longitudinal axis (A) in the direction of flow.
