Flat Die Granulator: The Magic Factory of Fertilizer Transformation

The Glamorous Makeover of Raw Materials
Before the granulation journey begins, raw materials undergo a "deep beauty treatment." Organic materials like livestock manure and straw first complete a 30-45 day fermentation "sauna," then are ground into 80-100 mesh powder as fine as baby powder. For compound fertilizer ingredients, elements like NPK are measured with bartender-like precision, requiring over 90% mixing uniformity and moisture content strictly controlled within the golden range of 15%-25%.

Perfect Shaping Under Pressure
The pretreated materials enter the granulator's "pressure chamber." Here, rotating rollers apply 10-30MPa of pressure (equivalent to 300kg concentrated on a coin-sized area), forcing material through precision holes in the flat die. The equipment operates at an elegant 10-30 RPM, like an experienced potter shaping clay into perfect forms.
