General introduction
The ceramic grinding mechanism are regularly comprised of 95% alumina or steatite. We usually use alumina for making reusable grinding burrs, and steatite for making disposable grinding burrs.
Alumina is a very hard, dense material of exceptional strength. It exhibits resistance to corrosion. Alumina grinders support refilling. In contrast, a steatite grinder has a top that can’t unscrew, so once the pepper is used up, people will throw it away.
Why choose ceramic burr?

Why choose steatite?
Steatite ceramic is used extensively in the disposable pepper mill, spice mill, or salt grinder. It is a lower-cost material than alumina (Al2O3) but has excellent electrical resistance properties (which are retained at high temperatures), along with moderate mechanical strength.
