Ceramic Grinding Burr Category

Ceramic grinding burr is commonly made of aluminum oxides or steatite, works as a most key component existing in grinder for pepper, salt, spice, herb and coffee. Due to its excellent wear resistance, eco-friendly and cost-effective features than plastic and metal ones. It has been recognized as an ideal grinding core in the market worldwide.


 We can offer a variety of standard types grinding ceramic burr, also customized design ones as client’s requirement including conical burr, flat burr and flat milling disc and so on. When you have any needs of ceramic grinding burr for pepper, salt, spice mill grinder, you can find suitable ones from our products.
 In addition, we have been supplying many classical types of pepper mill mechanism kit, pepper millstone, pepper mill parts kit. What’s more, we could offer optional grinder mechanism such as stainless steel and carbon steel grinder burrs in it according to different customer needs. Whatever, if you need a few prototyping samples, or cost down for mass production, we will provide you an optimized solution.

We classify products into three types:
1) Ceramic Burr for Seasoning Grinder
2) Ceramic Conical& Flat Burr for Coffee Grinder
3)Pepper Mill Mechanism
 you can find the products you need from our classification.

The ceramic grinding core in a seasoning grinder is a key functional component. Considering the food use, the raw materials must not contain any hard substances; in addition, due to the high frequency of use, they should have excellent wear resistance to reduce maintenance, also, the cost of raw materials needs to be appropriate. Fortunately, the properties of alumina ceramics and steatite ceramics just meet these requirements. Alumina ceramic grinding burrs and steatite ceramic grinding burrs have been widely used in various pepper, spice, salt and herb grinders in kitchens, restaurants.

Ceramic grinding burrs in seasoning grinders have a much longer lifespan than traditional plastic and metal grinding cores, and are much less expensive than stainless and carbon steel grinding cores.Most ceramic grinding burrs are produced by mold injection, which is easy to implement for various custom designs and for high volume production needs. We can customize to every need and also have over 30 different standard ceramic burrs to choose from.

The grinding burrs are the primary function parts to pulverize whole coffee beans into powder. Flat burrs are flat and have tiny teeth to grind the coffee beans into smaller particles. Conical burrs have a cone-shaped spinning inner burr and a stationary outer burr.

Ceramic burrs for coffee grinders are usually made of 95% or 99% alumina. Why do some famous coffee grinder manufacturers choose ceramic burrs instead of stainless steel? You will learn about these below:
1. Alumina ceramic is an eco-friendly material which meet FDA, LFGB regulations fully;
2. Alumina ceramic have much better wear resistance which is around 276 times than stainless steel.
3. The ceramic burr has so less heat in grinding that the flavor of fresh coffee bean powder can be maintained.
4. The ceramic burr has stable chemical properties, will not be oxidized in the air, nor will it react with acid and alkali.
5. Ceramic grinding cores have cost advantages and high production efficiency.
Our products can be made into white, gray, brown, black and other colors as required. Whether it is R&D samples produced in small batches or low-cost projects in large batches, we can provide the best solutions and ODM customized services.

Salt and pepper mill mechanism is the key functional component inside seasoning grinders. The lifespan of the seasoning tool, both the flavor and the grain size of seasoning output will depend on the type of internal grinding mechanism directly. 

In common case, metal grinding mechanism is more suitable for doing with dry peppercorns, spices, and ceramic grinding mechanism is more fit for working with salt and humid peppers. Considering the superb durability of ceramic grinding mechanism, corrosion resistance and much cost-efficient characteristics, many of grinder manufacturers have been using ceramic grinding mechanism in their both peppercorn and spice mills.

Our factory has been producing many standard types of salt & pepper mill mechanisms, pepper grinder parts, including ceramic types, stainless steel types and carbon steel types. In addition, we support customized ones with bespoke tooling. All these salt and pepper mill parts are conforming to FDA, LFGB regulations. 


All pepper mill mechanism kits we supplied are fully adjustable to grind different grain size from fine to coarse. They can grind a variety of toughest peppercorns, sea salt, spices. It will help you to significantly enhance the experience at your cooking time.

Product Introduction

The grinding burr is an essential part of the mill mechanism. We are producing ceramic grinding burrs in 95% alumina and steatite.

High purity alumina ceramic as a fine ceramic material is widely used in making reusable grinding burrs. This material has superb performances in wear resistance, corrosion resistance and environmental protection. Besides reusable grinders, disposable grinders are also common. We often use steatite for making disposable grinding burrs.

The most important difference between the disposable grinder and the reusable grinder is that the teeth of the disposable grinder is incorporated into the body of the bottle. This reduces number of parts in the grinder and hence not only gets rid of the cost of the fixed burr but also the cost of putting together the fixed as well as the rotating burr before they are placed into the jar.

Main Advantages of Ceramic Grinding Burrs

1.The ceramic grinding burr has a longer lifespanthan that of metal.
2. It will never rust.
3. Eco-friendly, healthy, electroless, no rust, safer than stainless steel.
4. It is cost-effective, low cost, but has good performance.
