Why Choose Ceramic Burr for Seasoning Grinding?
Advanced ceramic material (usually 95% alumina and steatite) is used in grinding burr applications due to its high hardness and excellent corrosion resistance. The product you are browsing is made of steatite.
Some people find it’s bothering about refilling or cleaning and maintenance. They prefer purchasing a new set of throwaway grinders because they are convenient and that is why they are called disposable. The grinding core of the disposable grinder is generally made of steatite.
Reusable Grinder vs. Disposable Grinder
Reusable Grinder | Disposable Grinder | |
PROS | Reusable Consistent in grind sizes Totally recyclable For the higher end market |
Easy to use No need to wash Cheap and affordable For the low-end market |
CONS | Relatively expensive Refilling may be troublesome Requires cleaning and maintenance |
Non-refillable / one-time use / disposable Doesn’t do well with grinding consistency Difficult to recycle |
About the Raw Material
Steatite is a silicate ceramic material based on soapstone. Typical steatite materials are mainly composed of SiO2 and MgO. Sintered at approx. 1300 °C, steatite exhibits the following critical properties:
high mechanical strength
age-resistant
Mechanical Property | Ceramic Material | |

Density (g/cm3) | ≥2.70 | ≥3.65 |
Water absorption (%) | 0 | 0 |
Hardness (HV) | 800 | 1500 |
Flexural strength (Mpa) | ≥190 | ≥320 |

How does the ceramic burr grinders work?
The burrs, looks like a grooved cone (Inner Ceramic Burr) set inside a grooved ring (Outer Ceramic Burr), acting like a drill bit with several rows of teeth.
First the ingredients get cracked in half by large teeth. Then they are crushed again between smaller rows of teeth into finer particles, as they travel down between the inner and outer burr.
A small adjustable screw at the top or bottom of the mill tightens or loosens the spring that brings the conical burr nearer to or farther from the outer ring of teeth, changing the coarseness of the ingredients.
