There are two basic kinds of coffee bean grinders. Blade grinders and burr grinders. Back before electricity was available, coffee beans were either smashed with a mortar and pestle, or after the technology was developed, smashed with a burr grinder. All those old wooden coffee grinders with the little wooden drawer in the bottom and the big metal handle on top are burr grinders. They have a set of gears in them that mesh with each other, drag the beans in and grind them up.
After the advent of electricity, and later high speed motors...somebody realized that it was a lot cheaper to just attach a blade to the motor, kinda like a little steel propeller, make it spin around real fast and dump some coffee beans into it and chop them up. It's really a coffee bean chopper, not a grinder. No grinding at all actually.
The coffee aficionados insist that the output of an electric chopper is not uniform and affects the taste. And also that the speed of the blades, burns the coffee slightly and affects the taste. I can't taste the difference myself. But I never claim to be an aficionado.
My amends for the long answer. To link this back to the long lost subject of the thread...some coffee aficionados might say the use of a blade coffee chopper is what's wrong with Americans.
