1. Why Choose Ceramic?
(1) Hardness of the ceramic grinding burr is close to that of diamond.
(2) It is not subject to rusting.
(3) Highly dependable and does not absorb tastes - keeping your flavors intact.
(4) It can be customized in different sizes and colors, suitable for different design styles of grinders.

Q1: Conical burrs Vs. Flat burrs
The highest-quality burrs are either flat or conical.
| Flat Burr | Conical Burr | |
| Appearance Features | Consist of two flat, ring-shaped burrs lined with grooves that break up the beans as the burrs press together. | More of a V shape, with the center burr fitting into the outer burr, both of them also lined with sharp-edged grooves that cut up the beans as they press together. |
| Advantages | More expensive Remarkably even particle size Best for commercial use | Quieter Consistent grind Good for home use and espresso |
