Coffee Burr machine or Grinder?!
Answers: What is the difference between a Coffee Burr Machine and a Coffee Grinder?
In the world of coffee grinders, you have two types. You have a blade grinder and you have a burr grinder.
The blade grinder is the least expensive one to make. It is basically a small bowl with a blade in it. A motor spins the blade to cut and break your coffee beans into particles for brewing. The problem with blade grinders is that the particle size is not consistent. If you try to make a course grind for a press pot, you will still have plenty of fine particles that can either plug your press or seep through and into your cup.
A burr grinder has a machined cone or burr that is adjustable in a feed shoot. The gap between the burr and the out feed area will set the particle size of the grind. The grind is much more consistent in size.
In making good coffee, the first step you can make is to start grinding your own beans. The next step would be to use a better grinder. If you know that you really like coffee, get a burr grinder to begin with. It will serve you well for many years.

It's the way it grinds the coffee. A 'grinder' tends to be a spinning blade. I think a 'burr' has more of a rotating disc set up.
A burr mill removes the variation in the grind size that you get in a blade based mill, and the coffee is subjected to a lower heat as it passes through the mill rather than remaining in the chamber while the blades continue to chop.
