Dicalcium Phosphate Plant, Voltage : 110V

Dicalcium phosphate is used as animal feed and ip grade. The plant uses phosphoric acid and calcium oxide or calcium carbonate as raw materials. Phosphoric acid and calcium carbonate are first reacted together with water, then fed to the updraft of the combustor where the reaction is finished and drying begins. The drying is coming from the reaction heat. No dryer is needed. It dries, sieves and mills dcp product to desired size. Secondly dcp will made by single super phosphate(ssp) it direct reaction with sulphuric acid  and powder rock phosphate

Plants based on following raw material :

• Based on sulphuric acid , rock phosphate & lime.
• Based on hydrochloric acid
• Based on phosphoric acid
• Based on single super phosphate(ssp)

Manufacturing of dicalcium phosphate process are of two types , first is direct phosphoric acid with calcium oxide reaction and second is based on the reaction with sulphuric acid and rock phosphate powder to produce single super phosphate.

If we use phosphoric acid for dcp production than first we make phosphoric acid with sulphuric acid 98%, ground rock phosphate 28-30% and water filter the react material by neutsche filter to separate the phosphoric acid and gypsum. Concentrate deflourinated phosphoric acid collected in mixing tank to mix lime solution with agitator. After complete reaction in mixing tank than precipitated dcp material do the filtration with filter press to separate the dcp wet cake and neutral solution. Filtrate   dcp wet cake put in to the electric oven in tray and dry it 2-3 hour to remove the moisture after drying remove from oven dcp material to pack into the bag with packing in 2,5,10,20,50 kg weight.

Secondly dcp process through single super phosphate (ssp) powder than to make single super phosphate with reaction of sulphuric acid 98%  and rock phosphate powder  28-30%   in paddle mixer and den conveyor , that’s are green ssp  to put for curing to complete reaction in heap for one weak . Cured ssp powder and water to take in mixing tank to mix with agitator after completion of mixing to separate solution and gypsum through neutsche filter / filter press / filter belt conveyor , filtered solution to collect in and other mixing tank to mix lime solution with agitator maintained ph 6.5-7.0  . After completion of mixing same procedure for both process as above as filtration, drying and packing
