Ammonium phosphates usually are manufactured by neutralizing phosphoric acid with NH3. Control of the pH (acidity/alkalinity) determines which of the ammonium phosphates will be produced. Pure grades can be easily made by crystallization of solutions obtained from furnace grade phosphoric acid. Fertilizer grades, made from wet-process phosphoric acid, do not crystallize well and usually are prepared by a granulation technique. First, a highly concentrated solution or slurry is obtained by neutralization. Then the slurry is mixed with from 6× to 10× its weight of previously dried material, after which the mixture is dried in a rotary drier. The dry material is then screened to separate the desired product size. Oversize particles are crushed and mixed with fines from the screen operation and then returned to the granulation step where they act as nuclei for the production of further particles. Other ingredients often are added during the granulation of fertilizer grades. The ratio of nitrogen to phosphorus can be altered by the inclusion of ammonium nitrate, ammonium sulfate, or urea. Potassium salts sometimes are added to provide a 3-component fertilizer (N, P, K). A typical fertilizer grade diammonium phosphate will contain 18% N and 46% P2O5 (weight).
There has been a trend toward the production of ammonium phosphates in powder form. Concentrated phosphoric acid is neutralized under pressure, and the heat of neutralization is used to remove the water in a spray tower. The powdered product then is collected at the bottom of the tower. Ammonium nitrate/ammonium phosphate combination products can be obtained either by neutralizing mixed nitric acid and phosphoric acid, or by the addition of ammonium phosphate to an ammonium nitrate melt.

 

 

      All Key Manufacturers and Suppliers of Baoji Guokang have routine inspections to ensure they are in compliance with the standards set in place during the original Supplier Assessment Inspection.

 

   Production Inspection Process:

Our Group service includes regular and thorough inspections throughout the manufacturing process, eliminating the need to employ additional quality control inspectors.

- Raw material before any production begins

- Pre-production samples to ensure specifications are being met

- In-process to confirm that standards are maintained

- Pre-shipping to ensure that the product arrives to the customer exactly as expected and is packaged

correctly to prevent any damage in transit.

 

   

     We can help operating split shipments, meeting the factory minimum quantity but ship them in 2 or 3 shipments with required gaps among. This allows you to move stock through your business without taking up space and capital.

We will arrange the subsequent shipments from our factory to your warehouse.

We can consolidate your small orders from multiple factories, delivering all at the same time to you or your customers,using the most cost-effective route available. At the time of order placement, we will offer details to you about the volume of each component part and what size container will be used.

 

    We can offer the complete package from concept to delivery; arranging everything up until products arrive at your own door or distribution hub.

   Delivery can be offered.

    - Utilizing your own freight-forwarder

    - FOB to a port in China

    - CIF to a port near you

   Whether you have your own freight-forwarder or you would like to organize shipment; whether you require delivery FOB in China or CIF to a port near you, we are glad to quote and supply whichever way you choose. Please feel free to discuss all options with us.
