Compound Fertilizer Equipment Benefit Analysis
Sep 05, 2017

Compound fertilizer equipment is a kind of equipment used to make chemical fertilizer by using the method of ammonia spraying. Drum steam production high concentration compound fertilizer granulation process, the disc without granulation of compound fertilizer production of high, medium and low concentration process, compound fertilizer anti-caking technology, high nitrogen compound fertilizer production technology, production of urea melt spray granulation of organic inorganic compound fertilizer technology, etc. Used to fill the domestic blank.

Fermentation process

Organic fertilizer production technology is mainly to water content less than 60% of organic solid wastes and accessories (plant straw, etc.), microbial fermentation bacteria agent evenly and fully by aerobic continuous fermentation pool type rotten, sterilization, deodorant, go to the water. The moisture content of raw materials is generally within 30-35% range. After selection and magnetic separation, it can be used directly for granulation to produce ball type organic fertilizer, or after further drying to produce powdery organic.

Granulation process flow

The process flow of compound fertilizer can be divided into: raw material ingredients, raw material mixing, raw material granulation, particle drying, granular cooling, particle grading, finished packaging film, final product packaging.

1. Ingredients:

Urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, and coarse whiting, ca), potassium chloride, potassium sulfate and other raw materials according to certain proportion with (according to the market demand and the around soil test results).

2. Stirring of raw materials:

The uniform fertilizer content of fertilizer granules was increased uniformly by mixing with good ingredients.

3. Raw material granulation:

The mixture will be sent into granulator granulator.

4. Dried grain:

The granule is put into the dryer, and the moisture in the granules is dried and the grain strength is increased.

5. Particle cooling:

After drying, the granule temperature is too high, easy to be caked, after cooling, it is convenient for bag preservation, and transportation.

6. Particle grading:

After the cooling particles were graded, the unqualified particles were crushed and regranulated, and the qualified products were sift out.

7. Finished film:

The qualified products are coated and coated to increase the brightness and roundness of granules.

8. Packaging of finished products:

The particles that wrap the film are stored in the ventilated place.

Tube reactor technology

This set of NPK production equipment has chosen to introduce the patented technology of "tubular reactor", including hardware and process software package, which is advanced in the world. The patented technology has a great advantage in product quality and the traditional neutralization reaction tank + ammonification process. Its characteristics are:

The granulation process is advanced

Products according to the compound fertilizer requirements, through the microcomputer ingredients measurement of all kinds of liquid and solid material in the granulator and chemical reaction in tubular reactor, synthesis of compound fertilizer, in ammoniation graining machine was wrapped in a row, and completely spherical particles, a variety of nutrients proportion can be up to standard, and stable and guaranteed.

Product granule nutrient equalization

Because it is chemical synthesis granulation, thus granular fertilizer nutrient content is the same as the logo, can according to certain proportion at the same time give NPK nutrients and other crops, to ensure balanced crop growth.

The particle size distribution of the products is uniformly distributed, and the particle size is about 2 to 4 mm. High particle strength, good fluidity, not broken during transportation, storage and stacking. In the engineering design, the third design institute of the chemical engineering department also incorporates the advanced technology of French AZF company and Spain INCRO, which further optimizes the design performance of the device.

Molten urine granulation technology

It can meet the requirements of producing various high nitrogen nutrient compound fertilizer. On the other hand, the granule quality can be further improved, so that the nitrogen nutrient of fertilizer granules is more balanced, and the surface is smooth and the gloss is high.

New technology of the spray slurry for the line reactor

Glycine tubular reactor spray granulation technology, the technology has solved the common equipment in the production of urea-based compound fertilizers for raw materials, production environment is poor, buckle and poor adaptation, product appearance and poor nutrient evenly and issue such as difference of agglomerate, long cycle and stable operation of products, this technology makes full use of steam, urine, gas ammonia urea enterprises, air, water, electricity and other utilities, can greatly reduce the fixed assets investment and operating cost.

How to make full use of the resources of organic waste is an important issue for China to build a resource-saving society, promote circular economy and develop organic agriculture. Is big fertilizer consumption in our country, the production of fertilizer consumes a lot of non-renewable resources such as coal, electricity, natural gas, the project development of utilization of organic solid waste circular spherical particle organic fertilizer production, achieve the goal of non-renewable resources conservation and environmental protection, social efficiency is huge, with the industrial policy of energy saving and emission reduction in our country.

Ecological environmental benefits

Increase organic fertilizer applying the content, can effectively solve the livestock and poultry breeding industry such as organic wastes pollution to the environment, reduce the nitrate content of groundwater by chemical fertilizer, reduce non-point source pollution caused by eutrophication of surface waters, is conducive to improve the quality of agricultural products safety, prevention and control pollution, ecological environment is extremely remarkable benefit.
