One cereal, several flours? Yes !
Our mill comes with a 300-micron sieve that enables you to obtain T80 flour. You can also choose to have several sieves to obtain different flours.
Here are the different sieves we offer:
- 300µ sieve (T80 equivalent), supplied with your Astréia mill
- Optional 470µ sieve (T110 equivalent)
- Optional 600µ sieve (T130 equivalent)

All you have to do is lift the sieve and replace it with an extra sieve of the same size, but with a different mesh.

How does the grain get from the hopper to the sieve?
In a nutshell:
- The cereal is stored in the hopper
- It is conveyed by a vibration system between the millstones via a trough
- The grain then passes between the millstones, between which it is unwound
- It is then conveyed from the millstones to the sieving plant via a spout that connects the mill to the sieving plant casing.
- It arrives in powder form in the sieve
- It then falls to the bottom of the sifting chamber in the form of flour.
