NPK Fertilizer Production Line

NPK Fertilizer Production Line

NPK Fertilizer Production Line, also widely known as a compound fertilizer production line or NPK fertilizer manufacturing equipment, is engineered to combine Nitrogen (N), Phosphorus (P), and Potassium (K) into uniform, nutrient-rich granules.

The NPK fertilizer production line is engineered to produce a wide range of complex fertilizers—including organic, inorganic, biological, and magnetic fertilizers. It is highly optimized for the efficient granulation of rare earth and ammonium bicarbonate series compound fertilizers.

Processing Raw Materials

Our compound fertilizer equipment is highly adaptable, designed to efficiently process a wide variety of raw materials for your NPK formulations. Common raw materials include:

Urea

Urea

Ammonium sulfate

Ammonium sulfate

Ammonium chloride

Ammonium chloride

Ammonium phosphate

Ammonium phosphate

Monoammonium phosphate

Crop Straw

Potassium chloride

Potassium chloride

Nitrogen (N) Sources: Urea, ammonium nitrate, ammonium chloride, and ammonium sulfate.

Phosphorus (P) Sources: Ammonium phosphate (including Monoammonium Phosphate / MAP and Diammonium Phosphate / DAP), Triple Superphosphate (TSP), and Single Superphosphate (SSP).

Potassium (K) Sources: Potassium chloride and potassium sulfate.

Final Products

NPK compound fertilizer

The end result is a highly marketable, water-soluble, and visually appealing npk granular fertilizer production line output.

Granule Size: 2–4 mm (customizable).

NPK Fertilizer Production Process Flow

The standard NPK fertilizer production process includes the following key stages:

Batching & Proportioning

Raw materials are accurately weighed and proportioned using a dynamic automated batching system. (For dry mixes, an npk blending fertilizer production line can be used here).

Crushing & Mixing

Materials are crushed into fine powders and thoroughly blended in a horizontal or twin-shaft mixer to ensure an even distribution of nutrients.

Granulation

The core of the compound fertilizer granulation line. The blended powder is fed into a granulator (rotary drum or double roller extrusion) where moisture or steam is added to form round granules.

Drying

Granules enter a rotary dryer to reduce moisture content to standard levels (usually below 2-5%), utilizing hot air up to 200°C.

Cooling

A rotary cooler rapidly drops the temperature of the dried granules to increase their physical strength.

Screening

A rotary screening machine separates the granules. Oversized and undersized granules are returned to the crusher and granulator for reprocessing.

Coating

Qualified granules are coated with a protective layer to prevent caking and nutrient loss.

Packaging

The final product is automatically weighed and bagged for distribution.

Core NPK Fertilizer Equipment

A reliable NPK Fertilizer Manufacturing Plant is only as good as its individual machines. Essential equipment includes:

Rotary Drum Granulator: The workhorse of high-capacity production, using steam and a liquid phase to ball the materials.

Double Roller Extrusion Granulator: Ideal for dry granulation without adding water, saving on drying costs.

Rotary Drum Dryer & Cooler: Essential for conditioning the granules for long-term storage.

Automatic Packaging Machine: Precision weighing and bagging for efficient dispatch.
