A mixing apparatus has a shaft, at least one arm radiating outwardly of the shaft, and a mixing element affixed to the arm away from the shaft. The mixing element has a generally frustoconical member with a wide opening at an end thereof and a narrow opening at an opposite end thereof. The mixing element also includes a throat section of a generally constant diameter connected to the narrow opening of the frustoconical member and a diffuser section having an end affixed to an end of the throat section opposite the frustoconical member. The mixing elements have a longitudinal axis extending at an acute angle to horizontal. A motor is cooperative with the shaft so as to rotate the shaft. Each of the mixing elements includes a Venturi.
