The following is an overview of Blade vs. Burr grinders.  Most electric coffee grinders are
the blade type.  We use the superior Conical Burr grinder!
"Burr Grinders
Burr grinders crush the beans between a moving
grinding wheel and a non-moving surface. The
positioning on the burr is what regulates the ground
size, which allows for a more consistent grind. In the burr
category, there are two different types.
Wheel Burr - The less expensive of the two burr grinders.
The wheel spins very fast, and these grinders can be
noisy. The higher speed rotation make these grinders
more messy as well.
Conical Burr - The best grinders you can get are conical
burr grinders. The burr spins slower than the wheel
model, which makes them quieter and less messy. You
can use a conical burr grinder for oily or flavoured coffees
and it's not likely to clog, like the other kinds of grinders.

Blade Grinders
Most inexpensive grinders use a metal blade to chop up
the beans. The blade cuts up the beans, and you control
the fineness by how long you let the grinder run.
Unfortunately, the resulting coffee grounds can be
uneven in size, leading to inconsistent brew quality.
Another downfall, is that if you are grinding finely, and
therefore leaving the beans in the grinder for a longer
period of time, there can be significant heat created by
the blades. This can give your final coffee a burned taste.
These are fine grinders for basic use, but that's about it."

Here is a look inside our grinder.  
Notice the burrs on the end of the
shaft.  This shaft turns crushing
the beans against the non-moving
burrs.
This view shows how the burrs interact with each other.  Our
mechanisms are fully adjustable and normally there would
not be this much room between the burrs.  The wider the
gap, coarser the grind (eg. French press).  They can also
be adjusted for a very fine grind (eg. espresso shots)
