the Basic Knowledge
1. About ceramic grinding burrs
1.1 Working principle
It looks like a fluted cone that fits inside a fluted ring, like a drill bit with rows of teeth.
First, the seasonings is split in half by the coarse teeth. They are then crushed into smaller particles again between the fine teeth as they travel down between the inner and outer burr.
An adjustable screw on the top or bottom of the grinder tightens or loosens the spring to move the inner burr closer or farther away from the outer burr, thus changing the grain size of the pepper, salt and spice powder.
1.2 Main characteristics
Ceramic grinding burrs have the characteristics of wear resistance, corrosion resistance,eco-friendly, less heat generate at grinding process, and will not affect the flavor of food, but much longer service lifespan.So they have great development potential in the field of grinders.
1.3 Material selection
The most common materials for ceramic grinding burr are 95% alumina and steatite. The burr in reusable grinders usually is made from alumina, while the burr in disposable grinders is made out of steatite.
① Alumina
High-purity alumina is widely used in the manufacture of reusable grinding cores. This material has excellent performance in wear resistance, corrosion resistance and environmental protection.
② Steatite
Steatite is another advanced ceramic. It has moderate mechanical strength and costs less than alumina ceramics.
Comparison of Material Properties
| Mechanical Property | 95% Al2O3 | MgO.SiO2 (Steatite) |
|---|---|---|
| Density (g/cm3) | ≥3.65 | ≥2.70 |
| Water absorption (%) | 0 | 0 |
| Hardness (HV) | 1500 | 800 |
| Flexural strength (Mpa) | ≥320 | ≥190 |
| Compressive strength ( Mpa) | ≥2000 | ≥551 |
| Fracture toughness (Mpam1/2) | 3-4 | - |

2.2 Type of grinding burrs
The type of grinding burr in the best seasoning generally includes ceramic, stainless steel, or carbon steel burrs. They have their own strengths and weaknesses in performance, you can choose according to your needs.
3. How to choose a grinder
3.1 Seasoning grinder
3.1.1 What food materials can be ground by the burr grinder
The ceramic grinding burr is suitable for grinding various seasonings, coarse cereals, herbs and spices, etc. You can refer to the applicable table below.
| Food materials you can grind | Small and uniformly shaped |
|---|---|
| Seasonings | Peppercorns like black pepper, white pepper, pink pepper and green pepper, chillis, sea salts |
| Coarse Cereals | Rices, wheats, linseeds, sesame seeds, soybeans, mung beans |
| Herbs and spices | Seeds of rosemary, mint, oregano, sage, thyme, parsley, basil, dill, clove, mustard, fennel, cardamom, cumin, cilantro, coriander, fenugreek, chive, star anise (crushed before grinding) |
3.1.2 Burr grinders Vs. blade grinders
A blade grinder does not guarantee the same grinding quality as a burr grinder. This is because blade grinders chop food materials in a rough and irregular manner. Burr grinders, however, pulverize food materials into particles of consistent size.
3.1.3 Disposable seasoning grinder Vs. reusable seasoning grinder
Reusable grinder supports refilling. In contrast, the top of the disposable grinder cannot be unscrewed, so once the seasoning is used up, people just throw it away. Refer to the table below for their performance comparison.
| Reusable Seasoning Grinder | Disposable Seasoning Grinder | |
|---|---|---|
| PROS | Reusable | Easy to use |
| Consistent in grind sizes | No need to wash | |
| Totally recyclable | Cheap and affordable | |
| For the higher end market | For the low-end market | |
| CONS | Relatively expensive | Non-refillable / one-time use / disposable |
| Refilling may be troublesome | Doesn’t do well with grinding consistency | |
| Requires cleaning and maintenance | Difficult to recycle |
3.2 Coffee grinder
3.2.1 Conical burrs Vs. flat burrs
True coffee experts will tell you that the best way to grind coffee beans is with high-quality burrs. There are two main types of coffee grinders on the market: with flat burrs or with conical burrs.
Conical burrs: Common in entry-level electric grinders and hand grinders due to their smaller size. When it comes to espresso, conical burrs tend to produce a better tasting grind. Because of their smaller diameter, they are generally slower.
Flat burrs: Typically used in commercial coffee machines. They are convenient, fast, consistent, and efficient, but expensive.
3.2.2 Can the pepper grinder be used to grind coffee beans?
No. Even if you have a great pepper grinder with the ability to adjust the grind setting based on the size of the grind (note that a coffee bean is about 10 times the size of a peppercorn), there are still two issues to consider: It is difficult to precisely adjust to the original position when switching between the two grinds. Second, your coffee will taste like pepper!
3.2.3 Are manual coffee grinders better than electric ones?
It depends on your needs. If you brew a lot of coffee, you’ll love the convenience of an electric grinder. However, for smaller brews, hand grinders are a good option, and they’re cheaper, quieter, smaller, and portable.
3.3 Simple troubleshooting
If your grinder is not working properly, you can refer to the following solutions.
3.4 How to clean
Clean the exterior of any grinder with a dry or slightly damp soft cloth. To clean the inside, use a soft, dry small brush to gently brush off any debris. If it gets wet, be sure to wipe it dry immediately after cleaning.
the Future Trends
The future development trend of ceramic grinding burrs mainly has the following directions.
AI Technology
By learning the user’s grinding habits and taste preferences, it can automatically adjust the grinding degree and speed to achieve a more personalized grinding effect.
Green and Environmental Protection
Made of biodegradable bio-ceramic materials, or made of recycled ceramic materials to reduce the impact on the environment.
Self-cleaning Design
Through the built-in cleaning device or automatic cleaning program, the grinding burrs can be cleaned and maintained more conveniently, and the life of the grinder can also be improved.
