    Blade Coffee Grinders

    A blade coffee grinder is a type of coffee grinder which uses propeller-like metal blades typically moving at speeds of 20,000 rpm to 30,000 rpm to chop up (smash) the whole coffee beans.  The grind size varies from fine to coarse, and this is controlled by how long you continue to run the grinder.

    What is Wrong with a Blade Coffee Grinder?

    A criticism of blade coffee grinders is that they produce an uneven grind size (e.g., smaller and larger particles), which leads to inconsistency in brewing. The blades also produce coffee dust that may clog the sieve in an espresso machine (espresso coffee maker) or a French Press.

    Excess heat may be generated when coffee is ground very fine using a blade coffee grinder, and this may essentially re-roast the beans and impart a burned taste to the coffee.

    The hopper is the part of the coffee grinder that holds the coffee beans during grinding.
