Conical Ceramic Burr: Unlike blade grinders, our electric grinder uses a conical ceramic burr that does not heat up during the grinding process. The slow and steady grind ensures that all the essential oils of the coffee beans are retained, better preserving the natural flavor and aroma of the coffee beans. Multiple Grind Settings: The portable conical coffee grinder has multiple grind settings to grind your coffee beans for any desired brewing method. With our electric coffee grinder, you will never have to worry about uneven coffee grounds. You can choose the precision of the powder according to your needs. Quieter than other coffee grinders: The average noise is 58-62 dB, which is quieter than other coffee grinders.
