Difference between burr grinder, blade grinder, blender, food processor in coffee grinding

Updated: Apr 7

Below is our former article you may be interested in.

Firstly let's check the basic principle of each appliance.

  • Burr grinder: This appliance has burr inside as its cutter to deal with the beans. There are different kinds of burrs for coffee making(flat burr, conical burr, ghost burr, etc). You can check above Blog 3 for reference.

  • Blade grinder: This grinder has a similar structure as the blender which has a sharp and thick blade inside the container to cut the material. It only has a small press button controlling the working status.

  • Blender: Blender is a very common appliance in our home and has many functions. It also relies on the sharp and thick blade to cut the material. The container is called"jar" and it is water-proof.

  • Food processor: It is an appliance similar to a blender, but the blade has a very different structure. The long and sharp blade leaves are all connected by a bar. It also uses the blade to cut the material. And the container is water-proof too.

Check our video for reference:

So let's check what will be the result of the coffee grinding.

Burr grinder:

Although we use a manual grinder, the burr grinder still did the best job. The powder it gets is very even and fineness is so good. It feels soft when you touch the powder.

Remark: I adjust to the finest for this test to make the test result obvious.

Blade grinder:

It works well too as we have tested it many times. It can break the beans into small pieces. But the particles are not even. Check the video and you will find the powders are only good for pour-over or similar coffee.


The mini blender we use did a better job than the blade grinder. It blends the beans better, but not better than the manual burr grinder.

Food processor:

I think normal size food processor can't blend coffee beans because of the result we get is just beans the same as we put. Maybe later we try some small size food processor to get the better result.


food processor< blade grinder<blender<burr grinder

Remark: these tools have so many different models, so I just do this test to show you a rough result. Maybe sometimes the result is totally different. But I think the result can reflect things in most conditions.

Thanks for reading
