In organic fertilizer production, the rotary drum granulator is the core piece of equipment determining product quality and efficiency. High-quality granulation not only improves particle uniformity and strength but also significantly boosts capacity while lowering production costs.

1.Optimize Raw Material Mix and Pre-treatment

The fineness and moisture content of raw materials directly affect granulation. Aim to crush materials to 20-40 mesh and control moisture between 25%-35%.Adding suitable binders like humic acid or bentonite can significantly improve particle formation rate and strength.

2.Precisely Control Operating Parameters

Rotation Speed: Typically keep it at 15-25 rpm. Too high causes particle breakage; too low reduces output.

Tilt Angle: The best angle is 2-5 degrees, adjustable based on material properties.

Temperature Control: Maintaining the rotary drum granulator temperature at 50-70°C helps moisture evaporate and particles harden.

3.Improve the Granulation Process

Using a “wet granulation + low-temperature drying” process preserves organic matter activity and avoids nutrient loss from high heat.And installing internal lifting plates improves material tumbling efficiency, leading to more uniform particles.

4.Upgrade to a Smart Control System

Adding a PLC automatic control system allows real-time monitoring and adjustment of feed rate, moisture content, and temperature.Smart control can increase production capacity by 15-20% while ensuring consistent product quality.

Choosing a high-performance rotary drum granulator and combining it with scientific production methods is key. This approach not only enhances fertilizer quality but also greatly improves production efficiency, making it a smart choice for modern organic fertilizer manufacturing.
