Ceramic grinding burrs are typically made of low cost steatite or high performance 95% alumina. Disposable Grinders, usually with steatite burrs, is very convenient to use and you don't have to go through the trouble of washing your grinders after use or refilling them when empty.
For those who want higher quality grinders, reusable ones with alumina grinding burrs is a good choice. Alumina has superb performances in wear resistance, corrosion resistance and environmental protection, providing ultra-long-life performance.
The product you're looking at is made of 95% alumina. It exhibits the following critical properties:
1. Never blunt and therefore never need to be removed for sharpening.
2. Anti-aging, corrosion resistance with longer service cycle and free of rust forever.
