Calcium Bentonite is a clay material made from natural bentonite ore through mineral processing, crushing and drying, with montmorillonite content ≥70%, expansion multiple ≥5 times, and cation exchange capacity ≥50meq/100g. It has certain bonding and adsorption properties, low price and abundant reserves. Widely used as an animal feed additive (mycotoxin adsorbent), a binder for metallurgical pellets, and a coating suspending agent, it can adsorb mycotoxins in feed and improve the pelletizing rate of mineral powder in metallurgy, and is an economical functional clay in the industrial field.
