Product Description

Agricultural grade bentonite/Improved soil bentonite 325 mesh-1250 mesh
For compound fertilizer granulation, it has the characteristics :
1.high granulation speed,
2.high ball rate,
3.uniform particle,
4.smooth surface, 
5.high particle strength and good water solubility of fertilizer.

When bentonite is applied to the soil, it can absorb water and swell, change the proportion of solid, liquid and gas in the soil, loosen the soil structure, improve the physical properties of the soil, make the soil retain water, keep the fertilizer without contaminating the soil environment, and in the arid area It is an extremely effective soil conditioner.

Bentonite other Properties

1. Proven to be one of the most effective sealants on the market

2. Swells much larger than its mass, then forms a strong water & chemical proof

3. Sodium bentoniteproduced by a naturally occurring mineral, environmentally-friendly

4. Acts as a hydrated aluminum silicate & it is a rock composed of crystalline clay like Montmorillonite  Mineral clay

5. High swelling & gelling properties

6. Strong viscosity with excellent colloidal properties

7. Animal feed grade

8. Fertilizer grade

9. Cosmetic grade

10. Cement/drilling factory
