Triple superphosphate (TSP) TSP fertilizer

Component Ca (H2PO4) 2, can be dissolved in water, preferably mixed with farmyard manure application. Can not be mixed with alkaline substances, otherwise it will form insoluble calcium phosphate and reduce fertility. Triple superphosphate applied to a variety of soil and crops, it can be used as basal fertilizer, fertilizer and composite (mixed) fertilizer raw materials. Widely used in rice, wheat, corn, sorghum, cotton, fruits, vegetables and other food crops and cash crops; for red, yellow, brown, yellow soil, black, cinnamon, purple soil, soil and other Albic kind of soil; for glass, plastic stability, assist livestock feed. The raw materials for manufacturing triple superphosphate rock phosphate and phosphoric acid production, the fineness of phosphate rock powder triple superphosphate general requirements for 80% to 90% passing 200 mesh. Concentration (including P2O5) 48% to 52%, temperature 60 ~ 70 ° C phosphoric acid and phosphate rock reaction 0.5 ~ 3min, slurry into stay indoors at 5 ~ 20min, after curing materials are chopped to the aging warehouse can factory aged for three to four weeks later. Manufacture granular triple superphosphate production methods, a concentration of 38% to 40% phosphoric acid in 2 to 3 series, with steam heated stirred reactor reaction 30 ~ 120min, temperature 90 ~ 100 ° C. The reaction slurry is fed into the granulator, fine aggregate and the system returns the granulation in the granulator, then dried and sieved to obtain a granular product.
