Blade grinders are good for basic use. They help you grind coffee beans. This inexpensive kitchen item is just about okay for normal use. The fact of the matter is that they do not really grind the coffee beans. They simply chop and smash them in to tiny bits, with the fast moving blades.
What happens is that by continually chopping the beans at high speed the end result is not very satisfactory. What you get is a grind that is inconsistent in size. So you get a lot of powder and chunks of coffee beans. The powder-sized particles could clog both a French Press and the espresso machine.
This isn’t the best way to grind coffee beans. Using metal blades that chop up the beans you can continually keep reducing the size. The blade grinders allow you to control the fineness of the ground beans depending on how long the grinder runs.
However the coffee thus ground is uneven in size, often leading to inconsistent brew quality. But what some of us may not like is the burned taste of the final coffee that occurs due to the substantial heat emanated in the grinding process.
