Compound Fertilizer Production Line

Our company offers the compound fertilizer production equipment with compact layout, scientific and reasonable design, and advanced technology. Furthermore, they have advantages of energy saving and consumption reduction, no environmental pollution, stable operation, reliable operation and convenient maintenance.

Its wide adaptability of raw materials make it applied frequently in compound fertilizer, pharmaceutical, chemical, feed and other industrial granulation, with a high granulation rate.
Basic raw materials of compound fertilizer production need to be crushed to a certain fineness, such as ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc.

Compound Fertilizer Production Process

Compound fertilizer process contains raw material batching, mixing, granulation, drying, cooling, screening, coating, packing parts.

Batching

Raw materials for compound fertilizer production are urea, ammonium nitrate, ammonium chloride, MAP, DAP, (heavy) calcium superphosphate, potassium chloride, etc. You need to blend the ingredients according to local market demands and results of soil detection.

Mixing

The crushed materials are mixed with some auxiliary materials to improve the overall fertilizer effect.

Granulating

There are various models of pelletizing machine, you can choose the right compound fertilizer granulation machine according your requirements.

Drying

The belt conveyor sends organic fertilizer granules to the dryer to reduce the moisture content and increase the strength.

Cooling

The fertilizer granules have higher temperature and are more prone to clumping after drying. Cooling can make them conveniently stored and transported.

Screening

After cooling, the pellets are screened, the qualified products are separated out, and the unqualified pellets are returned to the crusher and then re-granulated.

Coating

Qualified organic fertilizer granules are coated, which can effectively supply micro-elements and increase the brightness and roundness of the granules.

Packing

You can use the automatic packing machine to pack the finished organic fertilizer granules into bags and store them in a dry and ventilated place.

What Is The Equipment Needed for Compound Fertilizer Production Line?

1. Batching System

Batching system mainly consists of feeding system, weighing device, stock bin and conveyor belt. For instance, static batching machine has higher precision, better stability and easier measurement compared with dynamic batching machine.

Dynamic batching machine is suitable for continuous proportioning which is adaptive for large scale industrial production. It has higher working efficiency and degree of automation than static batching machine.

2. Mobile Belt Conveyor

Compared with the ordinary belt conveyor, it increases the mobile device and lifting device, which makes conveying capacity increase. Hence, we advise you can equip with a loader to change the appropriate place for loading and unloading materials.

3. Horizontal Mixer

Horizontal mixer is a generic mixing machine. It widely occurs in chemical industry, pharmaceutic industry, food processing plant, architectural material industry and other fields.

4. Rotary Drum Granulator

Rotary drum granulator is a molding machine that can make material to a specific shape. It is also one of the key equipment in compound fertilizer industry. Moreover, this machine has good appearance quality, corrosion and wear resistance, low energy consumption, long service life, simple operation and maintenance, etc.

5. Rotary Screening Machine

The rotary screening machine is commonly used in compound fertilizer production, which is mainly used for the separation of finished products and returned materials, but also achieves the classification of granules. Besides, the machine has easy maintenance, simple structure, easy and smooth operation, which is the ideal equipment in compound fertilizer production.

6. Rotary Coating Machine

Rotary coating machine consists of screw conveyor, rotary cylinder, oil pump, motor, reducer, and gears. It can effectively prevent the agglomeration of compound fertilizer. The inner cylinder consists of polypropylene or stainless steel with good corrosion resistance.

7. Packing Machine

The automatic quantitative packaging machine, which includes single bucket packaging scale and double one, is a mechanical device for quantitative weighing and packaging of granule and powder shape of bulk materials.
