Alumina Ceramic Components FDA Certificated Alumina Ceramic Grinding Mechanism For Pepper Mill


FDA Certificated Alumina Ceramic Mechanism For Pepper Mill

Material: 95% alumina, 85% alumina, steatite

The description of the ceramic mechanism
Ceramic mechanism is a key part of the pepper/spice/salt mill or grinder. It plays a grinding role. As advanced ceramics have superior performance, especially good toughness, wear-resistance, and eco-friendly, the ceramic grinding burr is a good replacement for plastic ones.
Besides ceramic mechanism is easy to get through molding, so the cost of the ceramic burr is much lower than metal ones. It's a very popular application in the disposable pepper mill, spice mill, or salt grinder.

1) High hardness.

2) High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.

3) Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.

4) High electrical resistivity: alumina is an electrically insulating material.

5) High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
