Abstract
Un procedimiento para preparar un fertilizante que contiene fosfato dicálcico a partir de un fosfato de origen mineral, en presencia de fosfato monocálcico, que comprende granular los granos mayores que 5 mm del fosfato tamizado o sin tamizar de origen mineral hasta un tamaño de grano de 1 a 4 mm, mezclar el fosfato con fosfato monocálcico y activar los cristales de fosfato haciendo colisionar los granos de la mezcla a una velocidad de 70 a 120 m/seg.A process for preparing a fertilizer containing dicalcium phosphate from a phosphate of mineral origin, in the presence of monocalcium phosphate, comprising granulating grains larger than 5 mm of the sieved or unsieved phosphate of mineral origin to a grain size of 1 at 4 mm, mix the phosphate with monocalcium phosphate and activate the phosphate crystals by colliding the grains of the mixture at a speed of 70 to 120 m/sec.
