Tribomechanical - this difference in zeolite grinding makes all the difference!
Conventional grinding processes are carried out using ball mills.
I recently took a closer look at such a mill. Huge spherical shapes made of various metals abrade minerals (such as zeolite). They are rubbed against each other until the raw material achieves the desired fineness. Such balls have to work for quite a long time until a fineness of 50 microns is achieved. These balls (sometimes discs) have to be replaced regularly because of high abrasion (metal).
And where does this abrasion come from during grinding with conventional ball mills?
Zeolite attracts metal, and thus the abrasion is absorbed by the zeolite and contaminates it. At the same time, the internal crystal lattices are crushed during this grinding. The effectiveness of the zeolite is subsequently minimized.
My brother always explains it with a Maltesers ball:
If you were to grind it, the internal cavities would ultimately be crushed and thus sealed. And that is exactly what we do NOT want!
And this is important to know about STEINKRAFT zeolite:
We do not have any of these issues with our STEINKRAFT products due to our special air pulverization (Air2Air) tribomechanical micronization: the crystal lattices are preserved, even more strongly broken down, the effectiveness is increased, and the zeolite is pulverized abrasion-free and finely.
What does this mean for you as a zeolite customer?
Always ask about the type of grinding. My observations are that up to 50 microns is almost always ground with ball mills directly at the mining site. In our laboratory, we can easily measure the grain size. Often, finenesses of 100 or more microns are present where 50 microns is stated. Last week, we measured a product allegedly 50 microns: it was clearly a rip-off. There were particles up to 300 microns in it. These products don't do much. Not even in the soil.
