Ceramic burrs are a pair of ceramic cones (or discs) with coarse and fine teeth. They work by using the shearing and grinding pressure generated by the relative rotation of the two cones (or discs) to break down ingredients into uniform particles.
Ceramic is not only hard but also naturally pure, never rusts, and will never affect the authentic flavor of coffee beans or spices.
Ceramic burrs can grind ordinary refined table salt, dry fine sea salt, and coarse sea salt for cooking. However, it cannot be used to grind wet, large-particle rock salt or mineral salt, as this may cause physical damage, blockage and clumping, and increased wear.
We cannot make any guarantees without knowing the specific structure of your grinder. Generally speaking, as long as your grinder uses standard-sized, replaceable ceramic burrs, our products are highly likely to be compatible. However, to be on the safe side, if you are purchasing in bulk, we recommend ordering a small quantity of samples for trial installation first.
If you use custom ceramic burrs, you will need to send us the drawings. We will assess the feasibility of production and provide you with a quote.
Rinse with water (no detergents) and dry thoroughly. Avoid grinding extremely hard materials (e.g., stones) to prevent chipping.
Yes, we have a grinder mechanism that comes with ceramic burrs and a stainless steel shaft. It’s perfect for grinding salt. Please contact us to learn more.
Technically it’s possible, but we don’t recommend it. The most serious problem is flavor contamination. Both pepper and coffee are intensely flavorful ingredients and absolutely cannot share a grinder without mixing flavors. Then there’s the issue of mismatched grind designs. Coffee flavor extraction requires extremely high particle uniformity, while pepper grinding doesn’t demand such uniformity. Finally, there’s the cleaning problem. The oils in coffee and the aromatic oils in pepper cannot be removed by simple rinsing.
Ceramic burrs are safe for everyday use. They are non-toxic, stable, corrosion-resistant, and do not easily damage the flavor of ingredients (such as coffee beans and pepper) during grinding. They are also washable.
Furthermore, our ceramic burrs have food contact material testing reports from authoritative laboratories and meet US FDA and EU food safety standards.
Yes, we can customize ceramic burrs. Our customization services include shape and specifications, tooth patterns and specific properties (such as the particle size of the ground powder), and laser marking. If you have any customization needs, please contact our customer service team directly via email or phone.
Some standard products are in stock. We can ship them within 2-3 business days. The standard lead time for customized products is 4-6 weeks.
