Description:
Every DECO Lab soil grinder is equipped with a round frame sieve. While grinded powder passing through the sieve, the particle can be classified into different sizes. The screen has 10 types including 20/ 40/ 60/ 80/ 100/ 120/ 140/ 160/ 180/ 200 sieve number. You can get different size powder by choosing the appropriate screen.
Matches between sieve & particle is as followed:
| Sieve number (mesh) | Particle diameter (μm) |
| 20 | 830 |
| 40 | 380 |
| 60 | 250 |
| 80 | 180 |
| 100 | 150 |
| 120 | 120 |
| 140 | 109 |
| 160 | 96 |
| 180 | 80 |
| 200 | 75 |
Note:
* For fragile materials: Input size: 10mm maximum; Output size: 0.1um minimum; Time needed: 20~30mins per time milling.
* For hard materials: Input size: 3mm maximum; Output size: 0.1~5um minimum; Time needed: Depends on the material hardness.
