Mainly there are two types of coffee grinders, conical burr grinders and flat burr grinders.
A flat burr grinder produces a remarkably even particle size, meaning that all the grounds are extremely uniform in size. For this reason, flat burrs are generally more expensive than conical burrs.
| Flat Burr | Conical Burr |
| More expensive Remarkably even particle size Best for commercial use |
Quieter Consistent grind Good for home use and espresso |
Product parameters
Our ceramic burrs for coffee grinders are made of high purity alumina (95%/99%/99.5%).They have no plating, no heavy metals, no rust, strong corrosion resistance, and can evenly extract coffee oil when the beans are precisely being grinded. In contrast, steel burrs can alter the expected flavor of the coffee by generating heat. Besides, grinders with ceramic burrs are relatively quieter during grinding.
