A process is disclosed for the production of granulated dicalcium phosphate dihydrate from fine-grained, powered dicalcium phosphate dihydrate, wherein 80 t0 95% of dicalcium phosphate dihydrate with a grain size of less than 120 .mu.m and 20 to 5% of calcium hydroxide with a grain size of less than 120 .mu.m are dry mixed and continuously sprayed and granulated in a fluidized bed with 20 to 50% of water, relative to the amount of solids, in which is contained an amount of phosphoric acid sufficient for the neutralization of the calcium hydroxide. The granulate obtained is dried at a temperature of 150.degree. to 200.degree. C., and the portions of coarse and fine grained material are optionally sieved off.
