What is the difference between a Conical burr and a flat coffee blade?
Grinder blades or burrs grind the coffee beans to consistent-sized particles.
Flat blades have smaller teeth that are used to grind the coffee beans into finer particles. Flat burrs work a bit differently since they spin at higher speeds for even consistent particles and is easier to adjust the grind
Conical burrs have a cone-shaped inner burr that spins where the outer burr is held stationary. Conic burrs are found in hand grinders and high-end high-performance grinders. With a conical burr, there will be some variation, very tiny particles that are called “fines” can occur with conic blades. Typically, it’s easier to dial in espresso shots with a conic burr, and calibration and alignment by the user are usually not required
How to clean coffee grinder blades?
