Ceramic grind core is the key functional part of the coffee grinder. How to find a suitable grinding burr? This ceramic flat burr is suitable for commercial or household electric coffee grinders. It is made of 99% alumina ceramics. The material has no coating, no heavy metals, no rust, and strong corrosion resistance.
When the coffee beans are ground accurately, it is not easy to generate heat, and the coffee beans ground with coffee oil can be extracted evenly, and the original flavor of coffee can be preserved. The environmentally friendly ceramic burr has a high heat capacity, so it can keep its original sharp edge for a long time, and it can also remain relatively quiet during grinding work.| Mechanical Property | Ceramic Material | |||
