This Tube Mill control is the world's first that was patented. This batch mill comes with a disposable grinding chamber. It gets rid of the effort cleaning takes as well as contamination that is involved. The chamber and the cover are created from transparent material so the testing can always be seen. This mill can work with brittle and dry materials. It works with grinding seeds like wheat and corn. In the creation of this mill, security was important. The mill will only turn on with the hood closed. If the chamber isn't properly in or closed right, the drive unit will bring an error message and it won't start. When running, the chamber can't be opened. Both have a labryinth seal.
