Vorschrift

continuously introducing into a pre-reactor (i) phosphate rock containing 66-75% tricalcium phosphate comminuted to a size such that 90% passes a 100-mesh screen and 70-80% passes a 200-mesh screen, (ii) phosphoric acid containing 38-54% P2O5 in an amount sufficient to provide a ratio of P2O5 to CaO in the reaction mixture of 0.7 to 1.0, and (iii) water in an amount sufficient to dilute the phosphoric acid to 38-44% P2O5,
