Product Description

Product Description

Ceramic Mill Burr / Ceramic Grinder Mechanism

Widely compatible with manual coffee grinders, electric spice mills, pepper & salt grinders, commercial kitchen seasoning equipment, supporting full-size OEM customization for global kitchen appliance brands.

Ceramic Burr / Ceramic Grinding Core / Ceramic Grinding Burr

Low-temperature grinding: Ceramic has a low thermal conductivity, so the grinding process generates almost no heat, preventing high temperatures from ruining the coffee's aroma and oils.  
No metal contamination: Natural ceramics are corrosion-resistant and don't rust, so they won't give your coffee a metallic taste, keeping the flavor pure.  
Long-lasting and wear-resistant: Extremely hard (Mohs hardness 7-8), generally lasting over 5 years, with a wear rate much lower than ordinary stainless steel over time.

grind particle deviation controlled within ±5μm, 87% less uneven coarse/fine powder compared with ordinary ceramic core.

 Consistent particle size for espresso, pour-over, French press, black pepper, sea salt without repeated secondary grinding.

Ceramic Grinding Burr

Raw Material: 95% / 99% High Purity Al2O3 Alumina Ceramic (customizable)
Mohs Hardness: 9 (close to diamond, stainless steel only Mohs 4.5)
Compressive Strength: ≥1850 MPa
Water Absorption Rate: ≤0.01% (zero moisture absorption, no mold & odor residue)
Self-wear Rate: ≤0.02% per 1000kg grinding material
Working Temperature Range: -20℃ ~ 320℃, no crack under long-term heating

The chemical properties of the material are extremely stable. When ground, it does not release metal ions or produce a rust-like smell like metals do. This allows the original natural flavor of coffee beans or spices to be retained to the greatest extent. 
Smoothly ground and not prone to overheating 
The ceramic grinding discs are mostly designed in an integrated style with a fixed pitch, maintaining a constant gap between the teeth.

This ensures that the powder is ground to a uniform consistency. Additionally, they have a low friction coefficient, and do not generate much heat during high-speed grinding, thus preventing the aroma from evaporating prematurely.
