Process Technology for Phosphoric Acid Production in
网页1992年1月1日 There are two main commercial processes to produce phosphoric acid: the wet process and the dry [ 1] (electrical furnace) process. Although, the acid produced (technical grade) with the dry process is pure, its production cost is much higher than that of the wet process phosphoric acid (WPPA or fertilizer grade acid).

网页2012年11月19日 Rock grinding. Until 1973, most phosphate was ground dry in roller or ball mills. In that year, Agrico, at South Pierce, Florida, converted one of its dry mills to wet slurry grinding and proved that the plant water balance could manage the rock at a 65–68% solids slurry. Since that time, most US installations have converted to wet grinding.
