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.

The reason of wear of the shell of double roller granulator
Zhengzhou SX professional technicians will analyze the reasons for the wear of the roller shell on the compound fertilizer production line on the roller granulator

1. raw material moisture, pH

The roller sleeve is made of stainless steel. It reacts strongly with the pH value of the substance. Improper moisture and pH of the material will cause acid-base corrosion on the roller surface and damage the roller surface.

2. material factors

Roller extruder mainly deals with dry powder materials. Due to the different hardness of the material, uneven forces will be produced during extrusion and ball formation, which will increase the wear of roller skin. From the perspective of material factors, the other factor is the uniformity of the raw material particle size. Different sizes of raw materials also lead to uneven force and wear of roller sleeve.

3. feed uniformity coefficient

The center of the axis of the parallel bar of the extruder is parallel to the surface of the roll skin. If the feed is seriously uneven, one end feeds more and the other end is fed less, it will cause uneven force at both ends of the roller, increase the friction between the roller and the material, and cause the roller to wear.

Measures to reduce the wear of the roller shell in the compound fertilizer production line of the roller extruder:
In the process of pelletizing of the roller extrusion granulator, the roller skin is inevitably worn.

However, if used properly, it can effectively reduce the wear of the roller skin, thus extending the service life of the roller skin. According to the above factors, the following aspects can reduce the wear of the granulator.

1. for materials with high moisture content and high pH value, inspection and adjustment shall be carried out.

2. roller material, it is very necessary to select the cylinder cover with good material, wear resistance, torsion resistance and corrosion resistance.

3. in order to supply working materials, the uniformity of feed must be controlled to avoid wear caused by uneven axial force of roller.
Effective maintenance is an important means to reduce wear.

In conclusion, the damage factors should be avoided in the daily operation of the compound fertilizer production line from to the roller extruder. Therefore, manual and conventional use can reduce the wear of the pelletizing roller of extruder, prolong the service life and reduce unnecessary waste.

Application of organic fertilizer throughout the year can renew or improve soil organic matter, improve soil physical and chemical properties, and significantly improve soil quality. With the rapid development of modern agriculture, fertilizer is essential. Fertilizer granulation plant sxfp will share with you the key points of rational use of organic fertilizer.

The advantage of organic fertilizer is that it contains a variety of nutrients, including a lot of micronutrients, and contains a lot of organic matter, vitamins and other active substances. The rational use of organic fertilizer should pay attention to the following points:

Pan Granulation Compound Fertilizer Production Line

Long term application of organic fertilizer can renew or increase soil organic matter, improve soil physical and chemical properties, and significantly improve soil quality. However, the disadvantage is that the nutrient content is low, and the nutrient form is mainly organic. It needs to decompose soil microorganisms gradually and transform them into the form of plant absorption and utilization. Because of the low nutrient supply intensity, it is difficult to meet the requirements of rapid growth cycle of high-yield crops. To use good fertilizer, the manufacture should choose a quality fertilizer granulation machine supplier, which will be the first and foremost thing.

In the process of organic fertilizer production, we should not only consider the characteristics of various organic fertilizers, but also consider the application of appropriate fertilizers. That’s what SXFP ALWAYS DO.

Rotary Drum Granulato for npk fertilizer pelleting

In terms of livestock manure, the amount of this organic fertilizer is very large. With the rapid development of livestock and poultry industry, livestock and poultry industry develops rapidly. If animal manure is not treated and applied scientifically, it will not only cause the loss of vegetables, fruit trees, tobacco, tea, potatoes and other economic crops, but also worsen the agricultural environment.

New Type Organic Fertilizer Production Line

Therefore, in the production of cash crops, it is necessary to fully develop and rationally use organic fertilizer. Because the main characteristic of organic fertilizer is that its nutrient content is higher than other organic fertilizers, the carbon nitrogen ratio (C / N) is relatively narrow, usually between 6 and 10.

Therefore, some crushed rice straw was added to form a mixed organic fertilizer, and then other NPK fertilizers were added and granulated by a double roll granulator. In this way, we can clean the environment and ensure the quality and safety of fruit and vegetable products. The application of organic fertilizer can partly replace the supply of nitrogen and phosphorus in crops, thus reducing the application of fertilizer and improving the utilization rate of fertilizer.

There are several benefits to this kind of granulator if compared to the standard models which are made. To begin with, this really is a roller fertilizer granulator, a device that may be created in a compact way. It offers steady rotation, is lightweight, and delivers a more highly precise product. It utilizes press rollers that may produce different shapes and sizes for your material which is produced. It utilizes metals that are resistant to abrasion, oxidation, and corrosion.
