Ⅰ.The Importance of Granulation Process

For granular fertilizers, granulation is far more than simply turning powders into granules. Functional ingredients such as humic acid, fulvic acid, beneficial microorganisms, and amino acids are sensitive to processing temperature, meaning that the granulation process can directly affect product activity and field performance.

Ⅱ.CityMax LTG Extrusion Technology Principles and Advantages

CityMax adopts LTG (Low-Temperature Granulation) extrusion technology, designed to maintain excellent granule quality while minimizing the impact of high temperatures on active ingredients.

Unlike conventional high-temperature granulation, CityMax’s LTG process does not rely on thermal melting. Instead, granules are formed by precisely controlling moisture content, extrusion pressure, and particle structure under low-temperature conditions. This gentler manufacturing process helps preserve the activity of microorganisms, humic substances, and other functional ingredients while reducing product moisture, increasing granule hardness, and minimizing breakage and dust formation during storage and transportation.

Another key advantage of extrusion granulation is the production of high-strength, uniformly sized granules. By carefully controlling granule structure, the products are better suited for broadcasting, basal application, and side dressing, reducing losses caused by powdering during application. The optimized particle structure also allows the granules to gradually interact with soil moisture after application, enabling a more stable and sustained release of functional ingredients.

Ⅲ.Citymax Product Introductionwhich adopts LTG Technology

Citymax DIAMONDMAX NO.2

Effective Viable Count:≥1×10¹⁰ CFU/g Bacillus subtilis+Bacillus licheniformis+Bacillus mucilaginosus:1×10¹⁰ CFU/g Humic Acid:18% Silicon Dioxide:15% Calcium Oxide (CaO):7% Magnesium Oxide(MgO):3% Iron (Fe):1.5% pH(1:100 Dilution):6.0-8.0 Particle Size(2.0mm-4.0mm):90% Appearance:Gray Irregular Granules

DiamondMax NO.2 contains ≥1×10¹⁰ CFU/g of beneficial microorganisms, combined with humic acid, silicon, calcium, magnesium, and iron. Through LTG low-temperature extrusion granulation, microorganisms, organic substances, and mineral nutrients are integrated into a single granule while maintaining both biological activity and physical stability. The product is specifically designed to improve soil health, stimulate root development, supply silicon, and enhance crop resistance to environmental stress and lodging.

Citymax ULTRA HUMIMAX-WSG

Humic Acid:80% Potassium(K2O):10% pH(1:100 dilution):9.0-11.0 Appearance:Black Flake/Powder

UItra HumiMax WSG features a high concentration of humic acid and is produced by using the same LTG low-temperature extrusion technology. The granules are uniform, highly durable, and fully water-soluble. UItra HumiMax WSG can be applied by broadcasting, drip irrigation, or liquid fertilization systems, making them particularly suitable for soil improvement, increasing fertilizer use efficiency, and promoting healthy root development.

Q: What are the advantages of CityMax’s extrusion granulation technology compared with conventional granulation?

A: CityMax utilizes LTG low-temperature extrusion granulation technology, which forms granules without high-temperature melting. This process minimizes heat exposure to active ingredients such as microorganisms, humic acid, and fulvic acid, helping preserve their functionality. At the same time, precise control of raw material moisture, extrusion pressure, and granule structure produces granules with low moisture content, high hardness, uniform particle size, and excellent resistance to breakage. These characteristics improve storage and transportation stability while ensuring more uniform field application through broadcasting or mechanized spreading. For multi-functional formulations, LTG technology also enables different active ingredients to be stably incorporated into a single granule, allowing the product formulation to deliver its full performance in practical agricultural applications.
