2. Process flowchart
A. melting of ammonium phosphate (urea)
Solid ammonium phosphate (urea) be crushed and weighing, send to melting vessel for melting, then send to 1# mixing tank.
B. phosphate (potash) salt powder system
Ammonium dihydrogen phosphate powder and fillers through weighing, be sent to 1# mixing tank to mix with ammonium phosphate (urea), then overflow to 2# mixing tank.
C. potash (phosphate) salt powder system
Potassium sulphate powder (ammonium phosphate) through weighing, be sent to 2# mixing tank, overflowing to evenly-mixer, from evenly-mixer to filtering trough, then to granulation machine to spray mixed slurry from top tower.
D. finished product
Granules from top tower will go to 1# sieve (1.8mm-4.3mm) and send to 1# cooling roller, nextly go to 2# sieve (1.8mm-4.3mm) and send to powder cooling device, through cooling to next procedure-coating roller, then through belt to 3# sieve (2.2mm), 1.8-2.2mm granules be sent to small size packaging area, 2.2-4.3mm granules be sent to big size packaging area.
