A centrifugal grinder with an internal grinding surface and a rotor turning within that surface includes a passage for inserting material axially into the rotor and a pocket to allow the material to contact the internal grinding surface. A spray is provided on the rotor at a location trailing the pocket, to spray liquid against the internal surface and make a slurry with ground material. An element of air-foil shape is mounted on the rotor at a location trailing the spray, the air-foil having a rounded contacting portion juxtaposed against the internal grinding surface, and have the effect of lifting the slurry away from the surface. A scoop trails the foil and has a leading edge juxtaposed against the internal grinding surface, defining a pocket for collecting the scooped-up slurry. A compartment is located axially beyond the grinding surface and a passage allows the scooped up slurry to pass from the pocket of the scoop to the compartment.
