Top 3 Crushing Techniques in NPK Fertilizer Production
In NPK fertilizer production, crushing is an important process to break compound NPKs into smaller particles for better mixing and granulation. Thus, there are three common crushing techniques, which are urea grinding, cage grinding and chain grinding technology.
This technology can break larger urea pellets and convert into fine powders to facilitate subsequent mixing and granulation processes. Typically, this method usually uses the gap between the roller and the concave plate to grind and cut urea particles into 0.3-0.5 mm. When it comes to capacity, SXNS-80 can dispose 5-8 tons of raw materials per hour, with the inlet moisture of less than 5%.
Cage crushing technology is suitable for grinding soft and brittle materials, such as industrial furnace slag, shale, medium hard coal, etc. Also, it can play a role in mixing and crushing multiple raw materials at the same time. In fact, the cage crusher has loose requirement for the raw materials’ water content, generally within 12%. When it comes to capacity, SXLSF-800 can process 6-10 t/h materials with 0.2 mm in size.
The last technique is suitable for crushing blocky and hard objects into less than 3 mm in compound fertilizer production like phosphate rock, coal, limestone, etc. For instance, our engineer develops two types of chain crusher. One is single shaft vertical crusher with the capacity of 2-3 t/h and the cheap price of $900. Besides, another equipment has two shafts with the largest capacity in NPK fertilizer crushing of 10-15 t/h.
These crushing techniques have a significant impact on breaking down raw materials into the desired particle sizes for further processing in NPK fertilizer production.
Top 2 Batching Techniques for NPK Compounds Processing
When it comes to the batching technology in NPK fertilizer production, our company has designed dynamic and static batching machines to ensure that the ingredient-mixing process has an error of less than 0.01. Besides, both of these machines have unique characteristics and applicability.
How to Fomulate 15-15-15 NPK Compound Fertilizer?
Taking a common NPK fertilizer formula as an example. Firstly, the proportion of NPK is 15-15-15, which means that the content of 15% N, 15% P2O5 and 15% K2O. Here are some details of this formula.
- Urea (nitrogen content 46%): Adding about 32.6%.
- MAP (phosphorus content 61%): Adding about 24.6%.
- Potassium sulfate (potassium content 52%): Adding about 28.8%.
- Other fillers and trace elements: Adding about 14%.
In the actual batching process, an operator will add various raw materials to dynamic or static batching machine according to the corresponding NPK ratio of the specific formulas. Then, you can add the necessary auxiliary materials to meet the requirements of the finished fertilizers. Additionally, the advanced control system automatically calculates the amount of each NPK component and strictly monitors the ratio during the batching process. Thus, this ensures the accuracy of the NPK ratio of 15-15-15.
Of course, we will ask the customer in advance if they are considering an automatic feeding system to reduce human intervention. As a result, this high-precision batching technology makes the NPK fertilizer production process more reliable and efficient, meeting the needs of different industries, including professional users in agriculture, horticulture, and soil improvement.
How to Make The Best Ratio in NPK Fertilizer Production Process?
In most cases, NPK ratio (N:P2O5:K2O) is 1-1-1 (e.g.15:15:15 or 20:20:20) will provide all of the nutrients that all plants require for optimal growth. Besides, here are some formulas for NPK fertilizer prodution are as follows/
Besides, you can make the NPK mixtures ratio of 4-2-3 or 4-3-2 for full growth period of crops.
Fertilizer factory can raise phosphorus content, like 1-2-1 NPK fertilizer ratios.
You can increase potassium ratios to 1-1-2, 1-2-2, or 2-1-2.
NPK fertilizer factory need to achieve 2-1-1 or 3-1-1 fertilizer ratios.
If you want to make accurate compound NPKs proportion, you need more than one high-quality batching machine. However, if raw materials contain large pieces that are difficult to handle, like DAP or other phosphorus sources, you should crush them firstly.
