Solution Grade Gypsum Calcium Sulfate fertilizer 50 pound bag 22% calcium and 17% sulfur AGC “Gypsum is our business, Custom is our creed” The ACG Materials ValuFil® 650 Calcium Sulfate Dihydrate, is a very fine, freeflowing, odorless, tasteless white powder produced by finegrinding and air separating a select grade of highpurity white gypsum.

Terra Alba No. 1 is a dihydrate form of calcium sulfate produced by fine grinding and airseparating highpurity, white gypsum containing 20% water of crystallization. It releases combined water as it is heated above 50°C, releasing 75% of water as temperatures reach 180°C (only when temperatures exceed 400°C is water totally removed).

This highyield process (approximately %) produces a relatively strong acid (approx. 36% of P 2 O 5) and a dry gypsum (less than 8% humidity) by natural rehydration of hemihydrate and dihydrate. Rehydration in this way substantially reduces the energy costs involved in drying the gypsum.

Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris 2CaSO 2 O.
