Raw material used per ton of 15-15-15 SSP fertilizer calculation

Calculate the raw material consumption for 1 ton of 15-15-15 compound fertilizer, you need to know the percentage composition of each nutrient in the fertilizer blend.

• For a 15-15-15 SSP fertilizer, it means that the fertilizer contains 15% nitrogen (N), 15% phosphorus (P2O5), and 15% potassium (K2O).

Here’s how you can calculate the raw material consumption:

1. Nitrogen (N):

   • Since the fertilizer contains 15% nitrogen, for 1 ton (1000 kg) of fertilizer:
     • Nitrogen required = 15% of 1000 kg = 0.15 × 1000 = 150 kg

2. Phosphorus (P2O5):

   • Similarly, the fertilizer contains 15% phosphorus (expressed as P2O5).
   • P2O5 required = 15% of 1000 kg = 0.15 × 1000 = 150 kg

3. Potassium (K2O):

   • The fertilizer contains 15% potassium (expressed as K2O).
   • K2O required = 15% of 1000 kg = 0.15 × 1000 = 150 kg

So, for 1 ton of 15-15-15 compound fertilizer, you would need:

• 150 kg of nitrogen source
• 150 kg of phosphorus source (usually as P2O5)
• 150 kg of potassium source (usually as K2O)

Why we should use the above Raw material 15-15-15 calcium ammonia nitrate fertilizer consumption table?

• Notice the equation in section 2 calculation only shows how much of each chemical elements is involved in 1 ton of 15-15-15 SSP fertilizer but it did not specify where these 3 elements comes from, therefore the above table we attached is very valuable, it is a internal document that is from a fertilizer plant manager, the table attached shows where the three element come from and how much each of these raw material is used, for example lets take Ammonia Chloride as an example from the upper table item number #1

Product	Composition%	N%	P%	K%	H2O%	Consumption%	Unit Price	Total Price
Ammonia Chloride	43.2%	25.4%	0%	0%	2.5%	0.434t	1000	434

What does this table means is:

• For each ton of 15-15-15 single super phosphate and calcium ammonia nitrate compound fertilizer, it contains 0.434t of Ammonia Chloride.
• For each ton of calcium ammonia nitrate compound fertilizer, ammonia chloride contains 25.4% Nitrogen(N)
• For each ton of 15-15-15 single super phosphate compound fertilizer, ammonia chloride contains 0% Phosphrous(P)
• For each ton of 15-15-15 compound fertilizer, ammonia chloride contains 0% Potassium(K)
• For each ton of 15-15-15 single super phosphate and calcium ammonia nitrate compound fertilizer, Ammonia chloride contains 2.5% water H20 that is to say. 
• For each ton of 15-15-15 SSP fertilizer, the price of ammonia chloride per ton is 1000RMB.
• For each ton of 15-15-15 calcium ammonia nitrate fertilizer, since each ton of ammonia chloride is 1000 RMB, and the consumption per ton of 15-15-15 fertilizer is 0.434t of ammonia chloride therefore the total cost is 0.434t *1000 rmb/t = 434 rmb
• Conclusion: each ton of 15-15-15 SSP calcium ammonia nitrate fertilizer consumes 0.434t of ammonia chloride and the raw material cost for ammonia chloride is 434 RMB.
• So here we notice that this formula 15-15-15 uses a lot of ammonia chloride as the N source, it is because economically, ammonia chloride is the cheapest for the source of N, other source of N might be more expensive or locally unavailable, therefore this is only for reference in this case. 

What are the sources for N composition in 15-15-15 SSP calcium ammonia nitrate fertilizer?

Common nitrogen sources in 15-15-15 SSP fertilizers include:

7. Organic sources such as compost, manure, or bio-based nitrogen sources.

15-15-15 SSP Compound fertilizer formula calculation Method step by step

• Raw Material Preparation:

1. Nitrogen fertilizer: Urea: 46-0-0-1 (H2O);
2. Ammonium chloride: 23.5-0-0-5 (H2O);
3. Phosphate fertilizer: monoammonium phosphate: 11-44-0-2 (H2O);
4. Potash fertilizer: Potassium chloride: 0-0-60-2 (H2O);
5. Filler: Clay: 0-0-0-6 (H2O);
6. Finished product index: N-P-K=15-15-15 H2O≦2%

• Calculation process:

1. The raw material of potassium fertilizer is single. Calculate the potassium dosage first.
   15/60=0.25 servings
   The preset moisture content of the finished product is 2%, the moisture content of the potassium raw material is the same as that of the finished product, and the difference is not calculated.
2. Phosphate fertilizer dosage:
   15/44=0.341 parts 0.341 parts Nitrogen content of monoammonium: 0.341×11=3.75
   The ammonium phosphate moisture content is 2%, which is consistent with the preset finished product moisture content, and the difference is not calculated.
3. Nitrogen fertilizer calculation:
   Excluding monoammonium for nitrogen supply, the amount of nitrogen supplied by nitrogen fertilizer: 15-3.75=11.25

• Because nitrogen fertilizers are available in urea and ammonium chloride, according to the granulation properties of the production materials, the optimal production formula should be a certain proportion of urea and ammonium chloride.

1. Assuming that all nitrogen is provided by urea, the dosage of urea is: 11.25/46=0.245 copies
2. Assuming that all nitrogen is provided by ammonium chloride, the amount of ammonium chloride is:11.25/23.5=0.479 copies

• According to production experience, this formula design is expected to use 0.15 parts of urea, then:

1. Urea nitrogen supply: 0.15×46=6.9
2. The amount of ammonium chloride for nitrogen supply is: 11.25-6.9=4.35
3. The dosage of ammonium chloride is: 4.35/23.5=0.185 parts
4. At this time, the moisture difference is: Urea: 0.15×(1-2)%= -0.0015 parts
5. Ammonium chloride: 0.185×(5-2)%= 0.00555 parts
6. The amount of filler is: 1-0.591-0.185-0.15=0.074 parts
7. The filler moisture difference is: 0.074×(5-2)%= 0.00296 parts
8. The comprehensive moisture difference is: 0.00296+0.00555-0.0015=0.00701 parts
9. The amount of filler after balancing the moisture content is: 0.074+0.00701=0.081 copies

• Calculation results:
  Potassium chloride: 0.25 parts
  Ammonium chloride: 0.185 parts
  Urea: 0.15 parts
  Monoammonium phosphate: 0.341 parts
  Filler: 0.081 parts

To summarize, we have introduced three things in this article, focusing on our raw material consumption table. This table is an internal document of the compound fertilizer factory, indicating which types of SSP calcium ammonia nitrate fertilizer will be consumed per ton. Raw materials, what is the NPK component ratio of each raw material, and what is the cost price per ton of each raw material. The second point of this article focuses on how to use the above raw material list, how to read the above raw material list, and how to use the raw material list to calculate the consumption of raw materials.
