Cone knife: the shape is close to a conical shape, the interior fits tightly, and the coffee beans are cut up through two tapered drills.

Flat knife: a flat blade in which coffee beans are ground in parallel as they pass.

Bean grinder blade material:

Hardened steel: this is the most commonly used material for bean mill blades, they are the standard for most bean mill manufacturing and models, and have all-round advantages in terms of grinding efficiency and cost-effectiveness.

Ceramic: this is a great substitute for metal blades, but when blunt objects or foreign bodies such as screws are encountered, their shortcomings are exposed and are easy to break or break (as shown in the following figure).

Titanium: titanium blades have a longer life and do not absorb heat quickly than non-standard hardened steel blades, but the disadvantage is that they are more expensive than standard steel.

Red Speed: titanium aluminum, they are used for large machines and extend grinding life, while Red Speed absorbs heat more slowly.
