5 Questions You Must Ask Your Zeolite Seller:
We want to contribute to education. And customers should develop a sense, an attitude, and be able to ask questions. Because sometimes we are very surprised at what is written in product descriptions that doesn't exist. Cannot exist. We then open our eyes wide and say: probably a typo.
We persistently receive emails in which Lifekraft Zeolite is rated with the predicate EXCELLENT. I already know this, but here it comes: I can buy it for 2,800.00 Euros for two years. Out of curiosity, I looked to see who had already bought this rating, which you can then use for one/two years. → What I want to say with this is, I understand why our customers are so confused and insecure. You can even buy an unverified quality criterion... This makes me sad.
Here you will find questions with which you can check and verify the quality of the zeolite and also the integrity of the seller. Prof. Dr. Hecht also checked us with these questions, and they were always very important to him.
1. Where is the zeolite mined?
Not all mining areas have the composition that zeolite needs to be considered a feed additive. The clinoptilolite content must be >80%. Not all can achieve this. So, ask for the country of origin. The Carpathians are long. They contain 3 different zeolite mining areas: Poland, Romania, Slovakia. With different compositions. More important than the clinoptilolite content, Prof. Hecht mentions the silicon to aluminum ratio. This should be at least 5:1. Even better, 6:1. That is, 6 times as much silicon as aluminum. This ratio also guarantees that the aluminum is firmly bound to the silicon and cannot detach. Never. So, look at the ratio. And here we are talking exclusively about natural zeolite. With synthetic zeolites, it is different.
2. What is the grain size/particle size of the zeolite powder?
Too coarse is too coarse. Because then it is not as effective, and if too little is dosed, you don't get the desired output. This is also why some users say: it didn't do anything. Then the zeolite powder was too coarse or was only vacuumed or sieved and not pulverized, opened up, and activated.
Have them show you the grain size measurement. It states exactly how much percentage is how big.

3. How was the zeolite ground?
The zeolite lattices must be opened up. Zeolite must be activated. This happens most gently and purely through tribomechanical micronization. The material breaks itself down. The particles collide with enormous speed in the airflow turbulence and grind themselves. This also creates the high basic energy and electrical charge. In comparison, there are ball mills that crush zeolite with high abrasion. The abrasion of the balls is already adsorbed. The result is that the zeolite is already quite saturated and no longer absorbs as much, and even worse, it is contaminated with heavy metals.
Again and again, we get photos where customers hold a magnet next to zeolite "dissolved" in water and then realize with a shock how black it becomes. Therefore, please pay attention. The finer zeolite is ground with conventional ball mills, the longer it is ground between the balls, and the more abrasion can occur. Recently, we heard and saw again that a zeolite seller had to recall a zeolite product because this batch was contaminated with many heavy metals. Heavy metals that get into the zeolite through the grinding method and perhaps also the transport. According to the cynical motto: a product that is supposed to detoxify, poisons. And all this ruins the reputation of this great natural all-rounder. Unfortunately.

4. How was the raw material transported?
Prof. Hecht instilled in us the importance of paying attention to this. Zeolite that is transported for long hours across Europe, possibly not sealed, as bulk material or in open BigBags or paper sacks, absorbs a lot from the environment due to its inherent adsorption capacity. Do the mining sites have sufficient quality standards? Or are there cross-contaminations because the trucks previously transported other materials, and these are still in the crevices of the truck bed, thus contaminating the zeolite? This is also why we only have zeolite from Eastern Slovakia delivered in sealed BigBags and then offer, for example, HORSEKRAFT zeolite in well-resealable buckets and cans. In horse stables, there are some animals that curiously gnaw at sacks and are very curious about open things.
Zeolite must be stored in well-resealable containers. Preferably in plastic containers (BPA-free, please) or glass containers. Zeolite absorbs. Attracts water and substances. Adsorbs. At Steinkraft-Zeolith, for cosmetics and as a feed additive, we looked at all paper sacks and definitively decided against them. Even those with internal coatings did not meet our quality criteria.
5. Was the zeolite powder produced by a registered feed manufacturer?
These have high quality standards that they must meet, and they are regularly and unannouncedly inspected by the feed authority. And the feed authority in Austria is extremely strict. They suddenly appear at the door and examine everything very closely. They check our internal controls and monitor that the feed law requirements for feed safety and feed hygiene are met. If anything is not right, it is immediately objected to, an official order is issued, and the feed manufacturer must react immediately. The Federal Office for Food Safety (BAES) ensures quick correction and optimization cycles.
That makes for a good feeling, doesn't it?
What we value at Steinkraft - most important criteria for zeolite summarized:
Importance of knowing quality criteria
We attach great importance to our customers understanding the quality criteria for zeolite and being able to make independent decisions. It is also important that customers can visually or tactilely assess the fineness of the powder. To this end, we plan to create a video to facilitate the identification and assessment of grain sizes.
Understanding "Ultrafine" in Zeolite Products
Many zeolite products are advertised as "ultrafine," but this can be misleading. A recently examined zeolite product for dogs, advertised as "ultrafine," actually had a grain size of 95 microns (d50). This means that 50% of the product is coarser than 95 microns (µm), which we at Steinkraft Zeolith do not consider ultrafine at all.
Different Grain Sizes and Their Applications
Zeolite products often vary in their grain sizes, often above 50 microns. In some mining areas, the raw material is sieved to 50 microns and sold as a commodity. Such grain sizes are suitable for industrial purposes but not recommended for other applications such as feed optimization, soil conditioners, foliar fertilizers, face masks, or tooth brushing.
Recommendations for Zeolite Grain Sizes
• Horses: Mean grain size [d50] of 24 µm.
• Dogs and Cats: 14 µm.
• Humans: 8 µm, recommended by Prof. Hecht.
• Slurry treatment: 35 µm, to float in the slurry and not settle.
• Foliar fertilizer: Less than 8 µm for effective absorption through the plant stomata.
• Cat litter: Coarser grains to avoid dust.
• Soil conditioners: A grain size of 100 µm is recommended.
Importance of the Grinding Process
The grinding process is crucial for the quality of zeolite. Ball mills that grind zeolite to 8 µm often cause abrasion that stresses the crystal lattices of the zeolite. A tribomechanical grinding process, such as our Air2Air Activation technology, prevents this abrasion and ensures higher purity of the end product.
Conclusion
To ensure the best quality and effectiveness, we recommend customers always check the grain size distribution and critically question it, especially when products are advertised as "ultrafine."
