Standard Alumina Ceramic Conical Burrs Overview
The standard ceramic conical burr set is manufactured from high-quality 95% alumina ceramic and designed for consistent grinding performance in pepper mills, salt grinders, spice grinders, and seasoning dispensers.
Compared with metal grinding mechanisms, ceramic burrs offer superior wear resistance, corrosion resistance, and flavor neutrality, making them an ideal choice for food-contact grinding applications.
Relevant outer ceramic burr dimensions are shown below.
Relevant inner ceramic burr dimensions are shown below.
The dimensional tolerance of the ceramic grinding core is approximately ±0.3mm. It is directly hot-pressed and sintered, which basically meets the assembly requirements of various grinders. If you require higher dimensional accuracy, we can also improve and meet it by adjusting the mold and forming conditions. The conical burr geometry allows efficient crushing and grinding while maintaining consistent particle size distribution.
95% alumina ceramic offers an excellent balance between hardness, durability, manufacturing cost, and grinding performance. It has become one of the most widely used materials for ceramic grinding mechanisms in household and commercial grinding equipment.
Key Advantages
The ceramic conical burr is a key part of manual grinders or adjustable grinding systems, there are following advantages:
Alumina ceramic possesses high hardness, allowing the grinding teeth to maintain their shape and sharpness over extended use.
Unlike metal burrs, ceramic burrs resist corrosion from salt, spices, and humid environments.
Ceramic materials do not react with food ingredients and help preserve the original aroma and flavor.
Precision-engineered grinding teeth provide stable grinding performance and uniform particle distribution.
The high wear resistance of alumina ceramic helps extend product lifespan and reduce replacement frequency.

Ceramic conical burrs are primarily used in pepper mills, salt grinders, spice grinders, and seasoning dispensers. Their conical geometry helps provide efficient crushing action and consistent particle size while maintaining long service life and food-safe performance.
Ceramic burrs generally provide better corrosion resistance, improved flavor neutrality, and excellent wear resistance. They are especially suitable for grinding salt and spices where metal components may experience corrosion or affect flavor over time.
Yes. Alumina ceramic burrs are widely used in salt grinding applications because they resist corrosion and wear caused by salt crystals. They provide reliable grinding performance even during long-term use in humid environments.
No. Alumina ceramic is chemically stable and does not react with spices, peppers, or salt. This helps preserve the original aroma and taste of ingredients while avoiding metallic flavors sometimes associated with metal grinding mechanisms.
Yes. Ceramic burrs can be customized in dimensions, grinding tooth geometry, surface finish, and assembly design. OEM production and customized grinding solutions can be developed according to customer drawings and application requirements.
