••• Burr grinders and blade grinders are two types of coffee grinders. ••• A benefit of burr grinders is providing a more even and consistent grind at the desired size. The two burrs aligned closer together grind the coffee beans until they are small enough to fall between the burrs. ••• There are two types of burr grinders, conical and flat, both of which are effective. Meanwhile, blade grinders use a spinning blade to powder coffee beans. The result lacks consistency in size and produces a lower quality ground.
