  I claim: 1. In a classifier which comprises a downwardly tapering chamber, means for withdrawing material respectively from lower and upper portions of the chamber,gypsum powder plant and an agitator disposed in the lower portion of the chamber, the combination which comprises a cage-like agitator in the lower portion of the chamber driven from the top by an 76 upright hollow shaft, a float disposed within the agitator and attached to a rod extending upwardly through the hollow shaft, means for increasing the speed of withdrawal of material from the lower portion of the chamber when said float is buoyed up and means operatively connecting the float and said means for increasing the speed of withdrawal.
  
  2. In a classifier circuit comprising a settling chamber, a wet grinding means, means for discharging wet ground material from the grinding means into an upper central portion of the settling chamber, means fV r withdrawing settled material from a lower portion of the settling chamber and returning it to the grinding means, and means for withdrawing unsettled material from an outer upper portion of the settling chamber, the combination which comprises a hydrometer disposed in the upper central portion of the chamber, means for supplying liquid to the wet grinding means,stone quarry machinery means operatively connected to the hydrometer and to the means for supplying liquid to the wet grinding means for increasing the amount of liquid to the wet grinding means when said hydrometer rises, a second hydrometer disposed in the outer upper portion of the chamber adjacent the withdrawal means for unsettled material, a plurality of conduits communicating with the settling chamber at points intermediate the top and bottom thereof, means for introducing water into the settling chamber through said conduits when said second hydrometer rises, means operatively connecting said second hydrometer and the means for introducing water into the settling chamber.
