Capacity of a coffee grinder

These devices have a millstone type of work and engine power from 300 W to 1 kW.
Grinded coffee grinders

You can buy mill millstone type, in which this indicator is regulated by means of special structural elements. Adjustment is performed by rotating the disc with notches, which is attached under the hopper. A 1-step turn accelerates the extraction time by an average of 2 seconds.
