Grinding core material: Al2O3 95%, SiO2 3.29%, CaCO3 0.25%, other 0.48%

Sintering temperature: 1680 degrees Celsius

Hardness greater than 1350HV5, high wear resistance, high temperature resistance

Product model: YCB-TC-AD 20260118016

Size: Height 18mm

Packaging size: 4.2 * 8.4 * 2.5cm

Total weight: 60 grams

Number of internal teeth: 5

Number of external teeth: 14

Unique design of grinding curve: The initial offset of the Archimedean spiral used for the outer teeth is 0.155, and the initial offset of the Archimedean spiral used for the inner teeth is 0.355,which can be adjusted

Durability: With extremely high hardness and almost no wear, it maintains precise grinding even after long-term use, and its lifespan far exceeds that of metal cutting discs. 

Uniform and stable grinding: no loss or deformation, high consistency in particle size, more balanced extraction, and cleaner flavor expression. 

Low temperature grinding: slow thermal conductivity, low heat generation due to friction, avoiding premature volatilization of aroma and retaining more flavor compounds. 

No odor, no rust: chemically stable, will not oxidize or rust, and does not produce metallic odor, suitable for grinding spices and salts. 

Easy to clean and maintenance free: can be directly washed with water, no residual powder adhesion, no need for oil maintenance, hygienic and safe.
