20,000 ton compound fertilizer production line

Short Description 

The annual production line of 20,000 tons of compound fertilizer is a combination of advanced equipment. Low production cost and high production efficiency. Compound fertilizer production line can be used for granulation of various composite raw materials. Finally, compound fertilizers with different concentrations and formulas can be prepared according to actual needs, effectively replenish the nutrients needed by crops, and solve the contradiction between crop demand and soil supply.

Product Detail

Composite fertilizer production line can produce high, medium and low concentrated compound fertilizer for various crops. The production line does not need to be dry, with small investment and low energy consumption.

The roller of the composite fertilizer production line can be designed into different shapes and sizes to squeeze and produce particles of different sizes.

Generally speaking, compound fertilizer contains at least two or three nutrients (nitrogen, phosphorus, potassium). It has the characteristics of high nutrient content and few side effects. Compound fertilizer plays a vital role in balanced fertilization. It can not only improve the fertilization efficiency, but also promote the stable and high yield of crops.

As a professional manufacturer of fertilizer production line equipment, we provide customers with production equipment and the most suitable solutions for different production capacity needs such as 10,000 tons per year to 200,000 tons per year.

Raw materials available for organic fertilizer production

Raw materials for compound fertilizer production include urea, ammonium chloride, ammonium sulfate, liquid ammonia, ammonium monophosphate, diammonium phosphate, potassium chloride, potassium sulfate, including some clay and other fillers.

1) Nitrogen fertilizers: ammonium chloride, ammonium sulfate, ammonium thio, urea, calcium nitrate, etc.

2) Potassium fertilizers: potassium sulfate, grass and ash, etc.

3) Phosphorus fertilizers: calcium perphosphate, heavy calcium perphosphate, calcium magnesium and phosphate fertilizer, phosphate ore powder, etc.

Work Principle

Generally speaking, the composite fertilizer production line generally consists of the following parts: mixing process, granulation process, crushing process, screening process, coating process and packaging process.

1. Dynamic Batching Machine:

The ingredients of more than three materials can be carried out. The batching machine has more than three silos, and can appropriately increase and reduce the silo according to customer's requirements. At the exit of each silo, there is a pneumatic electronic door. Under the silo, it is called a hopper, which means that the bottom of the hopper is a belt conveyor. It is said that the hopper and the belt conveyor are hung at one end of the transmission lever, the other end of the lever is connected to the tension sensor, and the sensor and pneumatic control part are connected to the computer. This machine adopts the cumulative weighing of electronic scales, which is automatically controlled by the batching controller, and the weighing ratio of each material is completed in turn. It has the advantages of simple structure, high ingredient accuracy, simple operation and reliable use.

2. Vertical Chain Crusher:

Combine different composite materials in a certain proportion and put them into a vertical chain crusher. The raw materials will be crushed into small particles to meet the needs of the subsequent granulation process.

3. Vertical disc feeder:

After the raw material is crushed, it is sent to the Vertical disc feeder, and the raw material is mixed and stirred evenly in the mixer. The inner lining of the mixer is polypropylene or stainless steel plate. Such raw materials with high corrosion and viscosity are not easy to stick to. The mixed material will enter the drum granulator.

4. Roll Extrusion Granulator:

Adopting dry extrusion technology, the drying process is omitted. It mainly relies on external pressure, so that the material is forced to be compressed into pieces through two reverse roller clearances. The actual density of the material can increase by 1.5-3 times, thus reaching a certain strength standard. Especially suitable for places to increase the product stack weight. The operation elasticity and wide range of adaptation can be adjusted by liquid pressure. The equipment is not only scientific and reasonable in structure, but also has little investment, quick impact and good economic benefits.

5. Rotary Drum Screene:

It is mainly used to separate the finished product from the recycled material. After sieving, qualified particles are fed into the wrapper machine, and unqualified particles are fed into the vertical chain crusher to make granulated again, thus realizing product classification and uniform classification of finished products. The machine adopts a combined screen for easy maintenance and replacement. Its structure is simple and fucked. Convenient and stable operation is an indispensable equipment in fertilizer production.

6. Electronic Quantitative Packaging Machine:

After the particles are screened, they are packaged by the packaging machine. The packaging machine has a high degree of automation, integrating weighing, suture, packaging and transportation, which realizes rapid quantitative packaging and makes the packaging process more efficient and accurate.

7. Belt conveyor:

The conveyor plays an indispensable role in the production process, because it connects different parts of the entire production line. On this compound fertilizer production line, we choose to provide you with a belt conveyor. Compared with other types of conveyors, belt conveyors have large coverage, making your production process more efficient and economical.
