Introduction

Looking to improve the appearance, durability, and efficiency of your fertilizer pellets? A complete fertilizer pellet coating production line is the key solution for adding a protective layer to your NPK, organic, or compound fertilizer granules. This coating process enhances fertilizer performance by reducing nutrient loss, minimizing dust, and enabling controlled or slow-release effects.

What is a Fertilizer Pellet Coating Production Line?

A fertilizer pellet coating production line is a specialized system used to apply a protective or functional coating to finished fertilizer granules. This process is commonly used in NPK fertilizer production, organic fertilizer granulation, and compound fertilizer manufacturing to:

• Prevent nutrient loss during storage and application

• Control the release rate of nutrients

• Improve resistance to moisture and caking

• Enhance product appearance and market value

Core Components of a Complete Fertilizer Coating Line

A complete fertilizer pellet coating production line typically includes the following equipment:

1. Fertilizer Pellet Conveyor System

Transfers finished granules from the granulator or dryer to the coating machine.

Can include belt conveyors, bucket elevators, or screw conveyors.

2. Fertilizer Coating Machine (Rotary Coating Drum)

The main equipment in the line.

Evenly over each pellet, apply liquid coating agents, such as polymer, sulfur, oil, or anti-caking agents.

Ensures uniform coverage and continuous production.

3. Coating Material Spraying System

Includes nozzles, pumps, and tanks for storing and spraying coating liquids.

Precisely controls flow rate and pressure for even application.

4. Dust Collector or Air Purifier (Optional)

Captures any coating material, mist, or dust during the process.

Ensures a clean working environment and operator safety.

5. Automatic Packing Machine

Final pellets are weighed, filled, and sealed into bags for storage or transport.

Supports manual or fully automatic packaging systems.

The fertilizer granule coating production line can directly improve the fertilizer granule effect, control nutrient release, improve storage performance, and enhance the competitiveness of your brand in the fertilizer market.

At the same time, we also sell NPK fertilizer production lines, organic fertilizer production lines, powdered compost production lines, compound fertilizer production lines, etc.
