Place of Origin: Guangdong, China
Material Introduction:
Made from high-purity alumina ceramic materials, this ceramic grinding core is designed for grinding equipment that requires wear resistance, heat stability, and low contamination. Alumina ceramic provides good hardness, chemical stability, and dimensional reliability for repeated grinding and friction applications.
Key Features:
High wear resistance for long service life
Good heat stability during continuous grinding
Smooth ceramic surface for cleaner material contact
Resistant to corrosion, moisture, and many chemicals
Custom tooth profile, center hole, slot, OD, ID, and tolerance available as part of our custom ceramic parts capability
Application Industries:
Coffee grinding equipment, spice and grain grinding machines, laboratory sample preparation, pharmaceutical powder processing, food-related grinding equipment, industrial powder processing, and precision mechanical equipment.
Lead Time:
Lead time depends on material grade, part size, tooth geometry, tolerance, quantity, and inspection requirements. Please send drawings, samples, photos, or equipment installation dimensions for evaluation before quotation. For custom projects, you can contact us through Contact Us.
This alumina ceramic grinding core is made from high-purity Al2O3 ceramic and is used in grinding equipment where wear resistance, heat stability, and clean material contact are important. It can be used for coffee, spices, grains, laboratory samples, pharmaceutical powders, and industrial materials. Sizes, slots, holes, and tooth profiles can be customized according to drawings or samples.

Material: 95%, 96%, or 99% alumina ceramic, selected according to working conditions and cost requirements.
Alumina ceramic is often used for grinding and wear parts because it has good hardness, wear resistance, heat stability, and chemical resistance. In grinding equipment, it can help reduce metal wear, corrosion, and contamination from worn metal parts.
CERAMPRO can produce alumina grinding cores by custom forming, sintering, machining, grinding, and polishing. If the part needs to fit an existing machine, we recommend sending drawings, samples, or installation dimensions before quotation.
