Flat Die Pelleting Machine: The Compact Granulation Specialist

Ingenious Design: Simple Yet Sophisticated

The working principle of the flat die pelleting machine is based on a direct and efficient design concept. It consists of a horizontally placed die (flat die) and a set of vertically moving press rollers. When raw materials are fed into the machine, the press rollers rotate on the die surface, forcing the material through the die holes to form continuous strands, which are then cut into pellets.

The greatest advantage of this design lies in its compact structure and easy maintenance. Compared to complex ring die pelleting machines, flat die machines have fewer moving parts, meaning lower failure rates and simpler maintenance procedures. This aspect is particularly appreciated by many farmers and small to medium-sized fertilizer producers whose technical teams may not be highly specialized, making equipment ease of maintenance crucial.

The die, as the core component, can be easily replaced as needed. Dies with different hole diameters can produce pellets ranging from 2mm to 12mm in diameter, accommodating various fertilizer formulations and crop requirements. Die materials typically use high-quality alloy steel, undergoing special heat treatment processes that ensure sufficient hardness while maintaining certain toughness, extending service life.

Multifunctional Adaptability: Beyond Organic Fertilizer Production

While the flat die pelleting machine excels in organic fertilizer production, its application scope extends far beyond:

Animal Feed Production: Processing grains, soybean meal, vitamins, and mineral premixes into nutritionally balanced pellet feed, improving feed utilization and reducing waste.

Biomass Pellet Fuel: Transforming agricultural waste such as wood chips, straw, and rice husks into high-density fuel pellets, achieving waste resource utilization.

Industrial Raw Material Granulation: Certain chemical raw materials and mineral powders also require granulation to improve flowability, reduce dust, and facilitate transportation.

This wide application range makes the flat die pelleting machine a truly multifunctional workstation, particularly suitable for small and medium-sized enterprises needing flexible production line adjustments. One machine, multiple uses, significantly improving return on investment.

Collaborative Operation: Complete Fertilizer Production Line

Although excellent on its own, the flat die pelleting machine requires harmonious cooperation with other equipment in a complete fertilizer production line to maximize effectiveness:

Raw Material Preprocessing System: Includes crushers and screening machines ensuring raw materials reach appropriate fineness and purity. Crushers break large raw material chunks into fine particles, while screening machines remove impurities and unqualified materials, providing high-quality raw materials for the granulation process.

Precision Batching System: Automatic weighing equipment and computer control systems ensure various raw materials are mixed according to precise proportions. This is crucial for producing compound fertilizers with specific formulations, guaranteeing nutritional balance in each batch.

Efficient Mixing Equipment: double axis mixer thoroughly blend various raw materials evenly, ensuring raw material consistency before granulation. Modern mixing equipment typically includes liquid addition systems that can uniformly spray binders or trace element solutions during mixing.

Post-Processing Equipment:

Dryers: Remove excess moisture from pellets, improving storage stability

Coolers: Reduce pellet temperature, preventing caking and mildew

Polishing Machines: Improve pellet surface smoothness, reducing dust generation during transportation

Packaging Machines: Automatically complete weighing, bagging, and sealing, improving packaging efficiency

Intelligent Control System: Modern production lines typically feature PLC or computer control systems, achieving automated monitoring and adjustment of the entire production process. Operators simply set parameters, and the system automatically controls the operating status of each equipment, ensuring process stability and consistency.
