Tribomechanical – this difference in zeolite grinding makes the difference!
Conventional grinding processes are carried out using ball mills.
I recently took a closer look at such a mill. Giant spheres made of different metals grind the minerals (such as zeolite). They are rubbed against each other until the raw material reaches the desired fineness. Such spheres have to work for quite a long time to achieve a fineness of 50 microns. These spheres (sometimes also discs) must be replaced regularly because of the high level of metal abrasion.
And where does this abrasion go during grinding with conventional ball mills?
Zeolite attracts metal, so the abrasion particles are absorbed by the zeolite and contaminated. At the same time, this grinding crushes the inner crystal lattices, thus minimizing the effectiveness of the zeolite.
My brother always explains it with a Maltesers ball:
If they were ground, the inner cavities would ultimately be crushed and thus sealed. And that's exactly what we DON'T want!

And this is important to know about STEINKRAFT zeolite:
We don't have any of this with our STEINKRAFT products thanks to our special air-pulverization (Air2Air) tribomechanical micronization: the crystal lattices are preserved, are even more broken down, the effectiveness is increased and the zeolite is abrasion-free and finely pulverized.
What does this mean for you as a zeolite customer?
Always ask about the type of grinding. My observations are that anything down to 50 microns is almost always milled with ball mills directly at the mining site. In our lab, we can easily measure the grain size. Often, even where the label says 50 microns, there are 100 or more micron finenesses. Last week, we measured a product that claimed to be 50 microns: it was clearly a scam. It contained up to 300 micron particles. These products don't have much effect. Not even in the soil.
But more about that in another blog article on the subject of grain size >>
