A Protocol for When to Adjust a Grinder Setting and When to Purge
When you adjust the grind setting on a grinder, you are moving the burrs closer together or further apart. Usually one of the burrs is attached to a plate that screws up and down on a thread when you twist the dial on the grinder. This means when you make the grind setting coarser, you are making it easier for the grinds to fit between the burrs because the opening is bigger.
