How Does a Coffee Bean Grinder Work?

Owning a coffee bean grinder is a great way to have great coffee. It gives you the freshest possible brew and can take your coffee experience farther than you could ever imagine. So, how does a coffee bean grinder work?

Blade Grinder
The cheapest type of coffee bean grinder is the blade grinder. This is a very simple concept. It is a flat blade that resembles one you would find in a blender or a food processor. This blade causes the coffee beans to bounce and the blades chop up them up. This often creates an uneven grind that has a lot of large coffee pieces and a lot of small coffee bean pieces. In fact, it even creates some coffee dust.

Burr Grinder
The next kind of grinder is a burr grinder. It has a disk in the hopper and it has burrs on one side of the disk. It then crushes the beans. In most cases it does this against the side of the bean hopper as the beans work their way down the chute. It also creates an uneven grind, but it is a lot more even then the blade grinder. These coffee bean grinders are a little more expensive and a better choice than the blade grinder.

Conical Burr Grinder
The final type of coffee grinder is the conical burr grinder. It has two disks with burrs in it. The coffee beans are then crushed between these two disks. Of all the grinders this one has the most advantages including a much more even grind while staying cooler, producing less sound, and even being a lot less messy. With all of these advantages in mind this is the best coffee bean grinder for your money.

For the blade grinder you have a hit and smash technique going on. For the other coffee bean grinders they are going to crush the beans to the desired size. Some are better at this than others, but it all boils down to crushing.
