Granule Making Machine Small Capacity Overview: Material Standards, Technical Specifications, and Performance Insights

Types of Small-Capacity Granule Making Machines

A small-capacity granule making machine is an essential piece of equipment in industries such as pharmaceuticals, agriculture, and animal feed production. These machines efficiently convert raw powders or fine materials into uniform granules, improving flowability, solubility, and storage stability. Below is a detailed overview of the most common types of small-scale granulation equipment, their working principles, applications, and performance characteristics.

Single Screw Extruder Granulator

An efficient and widely used machine for small-batch granulation, particularly in pharmaceutical and feed processing.

Advantages

• Simple and robust design
• Easy to operate and maintain
• Consistent granule size and density
• Ideal for heat-sensitive materials with temperature control

Limitations

• Lower throughput compared to twin-screw models
• Limited mixing efficiency for complex formulations
• May require pre-mixing of raw materials

Best for: Pharmaceutical granules, fertilizer pellets, animal feed, and research & development labs

How It Works: Single Screw Extrusion Process

The granulation process begins when raw powder or blend is fed into a hopper, which then gravity-feeds the material into the extruder barrel. Inside, a rotating screw conveys the material forward while applying shear and heat—either through external heaters or internal friction—to melt or soften the mixture. The homogenized, semi-molten material is then forced through a dies plate at the end of the barrel, forming continuous strands. These strands are immediately cut by a rotating knife into uniform granules. A downstream cooling conveyor or fluidized bed rapidly solidifies the granules, preventing agglomeration before packaging or further processing.

Pro Tip: For optimal performance, ensure raw materials are uniformly dried before feeding into the extruder to prevent clogging and inconsistent granule formation.

Cage-Type Granule-Making Machine

A mechanical agglomeration system ideal for producing high-quality organic fertilizer granules with excellent sphericity and strength.

Advantages

• Produces highly spherical and durable granules
• Effective for organic and compost-based materials
• Low energy consumption and compact design
• Uniform granule size distribution

Limitations

• Sensitive to raw material moisture content
• Requires precise control of spray rate and airflow
• Not suitable for thermoplastic materials

Best for: Organic fertilizers, compost granulation, soil conditioners, and eco-friendly agricultural products

How It Works: Cage-Type Granulation Process

In this method, raw organic materials—such as compost, manure, or plant residues—are introduced into a rotating cage or drum equipped with high-speed paddles or blades. As the machine rotates, the materials are continuously lifted and tumbled, promoting even mixing and nucleation. A fine mist of water or binding solution is sprayed into the chamber to initiate granule formation through agglomeration. Simultaneously, hot air is blown into the system to reduce moisture and harden the newly formed granules. After sufficient curing time inside the machine, the granules pass through a vibrating screen or rotary sieve to separate properly sized particles from fines or oversized lumps, which are typically recycled back into the process.

Rotary Drum Granulator

A highly efficient machine for producing compound fertilizer granules on a small to medium scale with excellent binding and coating capabilities.

Advantages

• High granulation efficiency and yield
• Excellent for NPK and multi-nutrient compound fertilizers
• Adjustable granule size and shape
• Compatible with liquid binders and coatings

Limitations

• Larger footprint than other small-scale machines
• Requires regular maintenance of seals and supports
• Potential for dust generation during operation

Best for: Compound fertilizers, NPK blends, slow-release nutrient granules, and commercial farming inputs

How It Works: Rotary Granulation Process

The process starts with the dry mixing of raw ingredients (such as urea, phosphate, and potassium) in a pre-mixer to ensure homogeneity. The blended powder is then fed into a slightly inclined rotating drum. As the drum turns, a controlled amount of liquid fertilizer or binding agent (like molasses or polymer solutions) is sprayed onto the tumbling material. This causes the fine particles to adhere and gradually grow into larger granules through a layering and compaction mechanism. The rotation speed, inclination angle, and spray rate are carefully calibrated to control granule size and density. After exiting the granulator, the warm granules pass through a rotary cooler to lower their temperature and improve structural integrity before being screened and packaged.
