The apparatus has a vertically oriented drive shaft (17) with a bladed impeller (33) attached to the drive shaft. A housing (20) surrounds a mixing chamber (21) in which the impeller is located. The lower end of a powder inlet tube (41) is disposed in very close proximity to the highest vertical extent of the impeller blades (42). A liquid enters the mixing chamber exterior of the powder inlet tube. The resultant slurry leaves the mixing chamber via a slurry discharge port (22).
