In a recirculating mixer assembly for liquid components the central cylinder section (7) incorporates a mixing chamber (15,16) which is emptied by a thrower (1). The novelty is that liquids are introduced into the mixing chamber by decentral pipes (15,16) the inlet valves of which are angled (14) to the central mixing chamber (12) and are hydraulically controlled (A,B) by a central cylinder (4).
