We have been making ceramic grinding parts for more than 15 years. Customized services are available. 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 | 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 |
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:
1. High mechanical strength
2. Age-resistant
| Mechanical Property | Ceramic Material | |
| MgO.SiO2 (Steatite) |

| Density (g/cm3) | ≥2.70 | ≥3.65 |
| Water absorption (%) | 0 | 0 |
| Hardness (HV) | 800 | 1500 |
| Flexural strength (Mpa) | ≥190 | ≥320 |
| Compressive strength ( Mpa) | ≥551 | ≥2000 |
| Fracture toughness (Mpam^1/2) | - | 3-4 |
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.
