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 |
Q2: Are manual coffee grinders better than electric?
It depends on your needs. If you brew a lot of coffee, you'll appreciate the ease of an electric grinder. However, manual grinders are great options if brewing in smaller quantities, and they're less expensive, quiet, compact, and portable.
Q3: How long do ceramic burrs last?
Ceramic burr grinders are durable and long-lasting, but they may eventually wear out with extended use. The lifespan of a ceramic burr grinder will vary depending on the quality of the grinder and how often it is used. If you use your grinder regularly, it is best to invest in a high-quality model that will last for many years.
