A different philosophy applies to the crushing and grinding of Gypsum. Gypsum as a mineral (CaSO4·2H2O) is number 2 on the Mohs scale of hardness; only Talc is softer. This would lead one to believe that it should be easy, to crush, like coal for example, and our equipment was formerly designed on this basis.

The highest concentration of heavy metal in gypsum brick was iron (Fe) with 3.13, 3.61, 3.66, 3.83 and 3.85 ppm for 10, 20, 30, 40 and 50%, respectively. The Fe concentration in the gypsum brick also showed a huge difference compared to the control brick, which was 0.033 ppm, which represented the permeability and durability of bricks [38].

When considering the specific gravity of heavy liquids, sorting with heavy liquids that have a specific gravity of 2.5 g/cm 3 is the least effective for concentrating each element. Concentration rates at specific gravities of 2.75 and 3.0 g/cm 3 have different tendencies for each sample and element, and no common characteristics are observed ...

InBio GYPSUM can help create favorable soil by lowering EC, as a high EC value of soil is undesired for the crop growth. High EC of soil can be due to fertilizer application as well as weathering of soil minerals. Gypsum, being readily soluble, results in proper buffered solute concentration (EC) in soil to maintain soil in a flocculated state.
