High-Precision Disc Granulator for Pigeon Health Grit Production

Overview: Custom Mineral Supplement Granulation

As a leading fertilizer equipment manufacturer, we recently developed a specialized production solution for a client in the avian nutrition sector. The challenge was to transform a complex blend of laterite (red soil), stone powder, and oyster shell powder into uniform, high-strength granules for pigeon health grit.

This mineral supplement is critical for pigeon digestion and skeletal health. By utilizing our heavy-duty disc granulator (pan pelletizer), we achieved a 95% granulation rate while maintaining the integrity of the raw materials.

The Challenge: Balancing Diverse Mineral Densities

Producing pigeon health grit requires blending materials with vastly different bulk densities:

1. Laterite (Red Soil): Provides essential trace elements but can be sticky.

2. Oyster Shell Powder: Rich in calcium but abrasive to machinery.

3. Stone Powder: Adds necessary grit for gizzard function.

The primary goal was to create a uniform spherical granule that wouldn't crumble during transport but remained porous enough for post-processing additives.

The Solution: Optimized Disc Granulation Technology

Our technical team selected the adjustable-angle disc granulator as the core of the production line. Unlike extrusion methods, the rolling motion of the pan pelletizer creates a more natural, rounded shape that pigeons find easier to ingest.

Key Equipment Features for Mineral Grit:

• Variable Speed Control: Allows precise adjustment of centrifugal force based on the moisture content of the laterite and shell powder.

• Adjustable Pan Angle: Ranging from 35° to 55°, enabling the operator to control the residence time and final granule size (typically 2mm–4mm for pigeons).

• Corrosion-Resistant Liners: Given the high mineral content, we utilized reinforced, wear-resistant scrapers to prevent material buildup and ensure 24/7 stability.

Post-Granulation: Enhancing Palatability and Nutrition

A unique aspect of this project is the post-pelleting enrichment. Pigeon breeders know that birds are naturally attracted to the scent of allicin (garlic extract).

Once the mineral base is formed and dried, the granules are move to a secondary coating stage where:

• Allicin is sprayed to improve "pigeon-friendly" palatability and provide natural antibiotic benefits.

• Essential Amino Acids are infused into the porous structure of the red soil and shell powder base, ensuring a nutritionally complete supplement.

Results and ROI

By transitioning to an automated pan granulator production line, the client reported:

• 93%+ Granule Uniformity: Reducing waste and dust during packaging.

• High Physical Stability: The granules withstand the physical blending of allicin and amino acids without breaking.

• Scalable Output: Capacity increased from small-batch manual mixing to a continuous 1-3 ton per hour industrial flow.
