Dynamic mixer, dispensing assembly and method of dispensing multi-component material from a cartridge

A dynamic mixer comprising:

• at least two inlets arranged at an inlet side of the dynamic mixer;
• an outlet arranged at an outlet side of the dynamic mixer;
• and
• a mixing element configured to be coupled via a coupling to a drive shaft to drive the mixing element about a longitudinal axis of the mixing element, the mixing element comprising a rotor body and at least three rows of rotor blades arranged one after another and projecting radially from the rotor body away from the longitudinal axis between the rotor body and a housing accommodating the dynamic mixer, the rotor body decreasing in size from the inlets towards the outlet at least over 30% of a length of the rotor body, a first row of at least three rows of rotor blades arranged at a different axial position along the longitudinal axis of the mixing element in comparison to the third row of the at least three rows of rotor blades at least three rows of stator blades are provided with a respective row of the at least three rows of stator blades being arranged in alternating arrangement with the at least three rows of rotor blades each of the at least two inlets formed by a passage having an inlet opening and a mixer entry opening formed adjacent to the first row of the at least three rows of rotor blades, a respective inlet opening for the at least two inlets arranged in parallel to the mixer entry opening, and in parallel to an outlet opening of the outlet.
