ABSTRACT:
The adjustable measuring device of the present invention has a housing containing an arcuate chamber guide having movable plates attached to it so as to define a metering chamber of variable size. The housing has a housing inlet at the top, communicating with a chamber inlet, and a housing outlet at the bottom, communicating with the metering chamber. An amount, predetermined by the size of the metering chamber, of material to be ground leaves a hopper, and enters the metering chamber through the housing inlet and the chamber inlet. The housing is slid, thereby closing the hopper, until the housing outlet is positioned over a grinding area. Then, the material is discharged into the grinding area to be ground.
