The conical burr coffee grinder is the best kind of coffee grinder you can buy. It is far superior to the metal blade grinder, whose metal blades chop your coffee beans very quickly resulting in an uneven coffee grind. They are also better than wheel burr grinders, which grind using a wheel in the same way that conical burr grinders do, except that a wheel burr grinder grinds quickly, make noise and somewhat of a mess. Conical burr grinders move slowly, preventing noise, mess, and clogging. Because of no clogging, you can use conical burr grinders on your favorite gourmet and flavoured coffees.
