There are mainly two types of coffee grinders on the market: with flat burrs and with conical burrs. We can't simply say who is good and who is bad when it comes to conical or flat grinding.
Most professional coffee drinkers feel that flat burrs give a more consistent grind, which results in a cleaner cup. Conical burrs, on the other hand, yield more fines and produce a cup with more body feel.
