Brief introduction of BB fertilizer production process:

1. The nitrogen, phosphorus, potassium, filler and other raw materials are transported to the relevant silos.
2. After weighing by each automatic metering device, it is sent to the premixer.
3. It is transferred to the horizontal BB fertilizer mixer (intermittent and continuous), the particles rotate through the horizontal BB fertilizer mixer to form an irregular curtain, and the evenly mixed particles incline slowly along the direction of the mixer. The discharge port rolls.

4. Transfer to the finished product bin, slide into the automatic packaging scale for weighing, packaging and warehousing.

The key to the production of BB fertilizer (mixed fertilizer) is as follows:

Follow the rules of chemical compatibility.

1. After mixing different base fertilizers, some reactions will reduce the critical relative humidity (CRH) and make the products absorb moisture and agglomerate. For example, urea and ammonium nitrate cannot be mixed directly. Because the CRH of the mixture is only 18.1%, most areas will absorb moisture, and some reactions will even cause nutrient loss, such as ammonium nitrogen (ammonium nitrate, ammonium sulfate, ammonium phosphate, etc.).

It should be mixed with alkali fertilizer with strong chemical activity (such as hot phosphorus fertilizer and potassium fertilizer) to avoid the loss of ammonium nitrogen (NH4-N). The addition of neutralizing agent (such as limestone, dolomite powder, etc.) in the mixed fertilizer also caused nitrogen loss.

2. Superphosphate and ammonium nitrate are mixed to form calcium nitrate [Ca (NO3) 2], which makes BB fertilizer (mixed fertilizer) viscous.

3. When superphosphate is mixed with urea, crystal water will precipitate, but ammoniated superphosphate can be mixed with ammonium phosphate to obtain stable synthetic fertilizer. Ammonium superphosphate is mixed with ammonium nitrate or urea and chlorinated. The product made from potassium is more dry and has better fluidity than that made from granular calcium.

The dry liquid mixed fertilizer with nutrient concentration more than 50% can be obtained by using ammonium phosphate formula, and the qualified calcium phosphate is only 25% ～ 31%. Calcium is mixed with ammonium sulfate. It starts to heat up, then it settles, the water gets wet and forms a hard lump.

Strictly use of grain based fertilizer to reduce secondary separation

1. The strength of basic granular fertilizer should be guaranteed first. Its static strength should not be less than 2 × 106pa, can bear the extrusion, friction and other external forces in the production process without pulverization.

2. The grain size range of each base fertilizer is – 6 + 16 mesh, and the dosage of each material is between 25% and 45%. When the difference of the middle particle size of different components is less than 10%, the mixture will not be separated again. In addition, the turbulence and storage in the mixing process are reduced, and the soft mixing is realized, which can effectively reduce the segregation and secondary separation of the mixed products.

As a professional fertilizer mechanism manufacturer in China, we produce various equipment, dumper, granulator, mixer, etc. for fertilizer plant. These are the main processes of chemical fertilizer production, but how is the transportation between machines? Yes, it depends on the belt conveyor, which is a necessary part of the production line.
We have a variety of belt conveyors, here we introduce belt conveyors and mobile conveyors.

With regard to belt conveyors, it can be used for horizontal and inclined transport. It is widely used in modern factories, such as coal, chemical industry, building materials, grain and other industries. Belt conveyor has the advantages of large volume, simple structure, convenient maintenance, low cost and strong universality. Continuous or intermittent movement of conveyor belts is used to transport powdery and granular goods. It is fast in operation, stable in operation and low in noise, and can be transported up and down.

Mobile belt conveyor is mainly used in places where loading and unloading places often change, such as fertilizer plant, coal yard, mine, warehouse, construction site, sand and stone yard, farm, etc. Short distance transportation, loading and unloading of materials or bulk materials with a single weight less than 100kg. It is a kind of continuous loading and unloading equipment with high efficiency and good maneuverability. It is light, beautiful and flexible. The rotary device is an electric drum, and equipped with tire wheels, which is convenient to move. The tilt angle and height are adjustable.

So you can see that the biggest difference between the two belt conveyors is that one is fixed, the other is detachable. Usually, the customer chooses the fixed one for transportation, the detachable one for packaging, or if you can pack only by manpower.

Classification characteristics and application of urea ammonium phosphate, aaty mmonium, phosphorus and potassium compound fertilizer. We also provide professional NPK fertilizer production machine and production line.

Urea ammonium phosphate

Ammonium phosphate of urea is composed of CO (NH2) 2 · (NH4) 2HPO4, which is made of ammonium phosphate and urea. Its nutrient content can be 37-17-0, 29-29-0, 25-25-0 and so on. It is a high concentration of nitrogen and phosphorus compound fertilizer. N and P nutrients are water soluble, and N: P2O5 is 1:1 or 2:1, which is easy to be absorbed by crops.

Ammonium phosphate urea is suitable for all kinds of soil and all kinds of crops, its fertilizer efficiency is better than the nitrogen and phosphorus content of simple fertilizer, and its application method is the same as ammonium phosphate.

Ammonium, phosphorus and potassium fertilizers

Ammonium phosphate potassium fertilizer is a ternary compound fertilizer made of ammonium sulfate, potassium sulfate and phosphate in different proportions, or by adding potassium salt into ammonium phosphate. The nutritional ratios were 12-24-12, 10-20-15 and 10-30-10, respectively.

The proportion of phosphorus in ammonium phosphate and potassium fertilizer is relatively large, so nitrogen and potassium fertilizer can be applied properly, and the ratio can be adjusted to give full play to fertilizer efficiency. Potassium ammonium phosphate fertilizer is a kind of high concentration compound fertilizer. How to make npk compound granules? Go here for more.

The third process is the granulation process of granular NPK fertilizer production line. In this process, the rotary drum granulator is an important equipment with a production capacity of 5-20 T / h.

Drum granulator is a kind of molding machine which can make material into specific shape. It is one of the key equipment of NPK compound fertilizer production line, suitable for cold and hot granulation and batch production of high and low concentration compound fertilizer. The main working mode is wet granulation.

Pelletizing process fertilizer production line

The rotary drum plays an important role in the granulation process of the world-class 50 million T / a NPK compound fertilizer production line.
