Compound fertilizer production equipment

Compound fertilizer production equipment.

The compound fertilizer is a single fertilizer in different proportions for mixing ingredients, and a compound fertilizer containing two or more elements of nitrogen, phosphorus, and potassium is synthesized through a chemical reaction.

The nutrient content is uniform and the particle size is uniform. The compound fertilizer production line has a wide range of adaptability to the granulation of various compound fertilizer raw materials.

The raw materials for compound fertilizer production include urea, ammonium chloride, ammonium sulfate, liquid ammonia, monoammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfate, and some fillers such as clay. In addition, organic materials such as various animal manures are added according to the needs of the soil.

The compound fertilizer production line can produce high, medium and low concentration compound fertilizers for various crops. The production line has the characteristics of small investment, low energy consumption, uniform granulation, bright color, stable quality, and easy dissolution and absorption by crops.

Compound fertilizer equipment usually includes: 　

1. Mixing equipment: horizontal mixer, double shaft mixer

-After the raw material is crushed, it is mixed with other auxiliary materials and then granulated.

2. Crushing equipment: vertical crusher, cage crusher, double shaft chain mill

-The grinder is widely used in the organic fertilizer production process, and has a good crushing effect on wet raw materials such as chicken manure and sludge.

3. Granulation equipment: rotary drum granulator, double-roll extrusion granulator

-The granulation process is the core part of the organic fertilizer production line. The granulator achieves high-quality uniform granulation through continuous mixing, collision, inlay, spheroidization, granulation, and compaction processes.

4. Drying equipment: drum dryer, dust collector

-The dryer makes the material fully contact the hot air and reduces the moisture content of the particles.

5. Cooling equipment: drum cooler, dust collector

-The cooler reduces the water content of the pellets while reducing the temperature of the pellets.

6. Screening equipment: drum screening machine

-Both powders and granules can be screened out by a drum sieving machine.

7. Coating equipment: Coating machine

-Equipment for coating powder or liquid on the surface of fertilizer particles to realize the coating process.

8. Packaging equipment: automatic packaging machine

-The automatic quantitative packaging machine can automatically weigh, transport and seal the bag.
