NPK compound fertilizer production line

The NPK compound fertilizer production line is specifically designed for producing compound fertilizers with different nutrient ratios and formulations. This production line utilizes advanced granulation technology, offering advantages such as low investment, high granulation rate, stable operation, and high economic benefits.

This production line is widely used in the production of NPK compound fertilizers, organic fertilizers, inorganic fertilizers, bio-fertilizers, and other mixed fertilizer products. The system supports various raw materials and can produce fertilizers of different concentrations and specifications according to customer requirements.

This production line features one-time granulation, compact structure, simple operation, low energy consumption, and high production efficiency, making it suitable for fertilizer plants, chemical enterprises, feed companies, and pharmaceutical granulation projects.

High granulation rate, uniform fertilizer particles, stable operation, low energy consumption, compact structure, small footprint, simple operation, convenient maintenance, strong corrosion resistance, long service life, suitable for various fertilizer raw materials, automatic control system improves production efficiency, environmentally friendly, and low dust pollution.

1. Automatic Batching System

According to fertilizer formulation requirements, different fertilizer raw materials are accurately weighed and proportioned.

2. Fertilizer mixing equipment

The raw materials are uniformly mixed after batching to improve the uniformity of nutrient distribution in the fertilizer granules.

3. Granulator

The mixed raw materials are fed into the granulator to form fertilizer granules with uniform size and high strength. The granulator is one of the core pieces of equipment in the NPK compound fertilizer production line, featuring excellent granulation performance, corrosion resistance, low energy consumption, and long service life.

4. Drying and cooling equipment

Fertilizer granules produced by granulators contain a certain amount of moisture. Drying and cooling equipment removes excess moisture, increases granule strength, and facilitates storage and transportation. After drying, the fertilizer granules are still at a high temperature. Cooling machines lower the granule temperature, prevent clumping, and improve storage conditions.

5. Screening Machine

The screening machine classifies the fertilizer granules into qualified and unqualified products. Qualified granules proceed to the next process; oversized or undersized granules are crushed and returned for regranulation. Rotary screening machines are widely used in compound fertilizer production lines due to their simple structure, stable operation, and ease of maintenance.

6. Coating Machine

Qualified fertilizer granules undergo a coating process to improve their appearance, smoothness, and anti-caking properties.

7. Automatic Packaging Machine

Finished fertilizer is automatically weighed, bagged, and packaged for storage and transportation. This packaging system supports both powdery and granular materials.
