1. Ceramic burrs tend to stay sharper for longer than their metal counterparts. This means that you won't need to replace your grinder as often.
2. The ceramic grinding burr is easy to wash without leaving impurities.
3. Food-grade material and compliant with FDA, LFGB and RoHS standards.
4. Support various customized sizes per clients' drawings or samples.
The product you're looking at is made of 95% alumina.
High purity alumina as a fine ceramic material is widely used in making reusable grinding burrs. This material has superb performances in wear resistance, corrosion resistance and environmental protection.
