Component Specifications

Definition
Internal lifter plates are strategically positioned steel plates mounted on the inner wall of rotary drum granulators used in compound fertilizer production. These plates lift the fertilizer mixture as the drum rotates, creating a cascading motion that enhances material mixing, agglomeration, and heat transfer during the granulation and drying processes. Their design directly impacts granule size distribution, density, and production efficiency.
Working Principle
As the rotary drum rotates, internal lifter plates scoop and elevate the fertilizer material to a predetermined height. When the material reaches the apex, it cascades back down in a curtain-like shower, exposing maximum surface area to hot air streams. This continuous lifting and cascading action promotes uniform coating of particles, efficient moisture evaporation, and controlled agglomeration through repeated contact between particles and binding agents.
Materials
Typically constructed from abrasion-resistant steel (AR400 or AR500), stainless steel (304 or 316 for corrosive environments), or carbon steel with protective coatings. Material selection depends on fertilizer composition, operating temperature (typically 80-200°C), and corrosion resistance requirements.
Technical Parameters
  • Spacing 300-600 mm along drum length
  • Plate Height 150-300 mm
  • Mounting Angle 45-60 degrees
  • Surface Finish Smooth or textured depending on material flow characteristics
  • Plate Thickness 8-16 mm
Standards
ISO 9001, DIN 8580, ASME B46.1

Frequently Asked Questions

What is the primary function of internal lifter plates in rotary drum granulators?

The primary function is to lift and cascade fertilizer material to create uniform mixing, promote agglomeration, and enhance heat and mass transfer during granulation and drying processes.

How do lifter plate design parameters affect granule quality?

Plate height, angle, and spacing directly influence material residence time, cascading pattern, and particle collision frequency, which determine granule size distribution, density, and sphericity.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
