Dynamic mixer

A dynamic mixer for low viscosity to high viscosity components, having

• a rotor;
• and,
• a housing, which has front inlet openings for the components and at least one rear outlet opening and the inner space of which includes a pre-chamber and a main chamber,
• with the pre-chamber opening into the main chamber in a distal, tapering transition section, the tapering transition section comprising a conical surface extending between the pre-chamber and the main chamber, the conical surface being disrupted by at least one channel as a passage from the pre-chamber into the main chamber,
• wherein the at least one channel comprises a surface opening on the conical surface, the surface opening extending between a closed end and an open end, the open end opening into the main chamber with the width of the at least one channel extending over a part of the periphery of the transition section,
• wherein the length of the at least one channel extends axially over essentially the entire transition section and
• wherein a portion of the rotor has at least one opening configured to align and coordinate with the at least one channel such that a volume flow of the components to the main chamber from the pre-chamber through the transition section occurs only from the opening in the rotor into the surface opening on the conical surface and out through the open end of the at least one channel.
