Capacity:
The removable bean hopper holds ½ a pound of coffee beans.

 

Conical burrs:
The bottom burrs are driven by the motor and the top plate is stationary. The distance you position them apart precisely determines grind size. The center cone moves. A high gear reduction allows for a slow grinding speed. This allows less heat while grinding to not burn the coffee. 

 

Adjustable settings:
The easy-to-read settings allow for grind choices from ultra-fine for Turkish coffee to large and coarse for percolators
