Amidst the wave of green agricultural transformation, organic fertilizer granulation equipment is undergoing a profound shift from “crude extrusion” to “precision intelligent manufacturing.” Since 2025, a new generation of organic fertilizer granulators—integrating materials science, intelligent control, and biotechnology—has rapidly entered the market. These machines are no longer merely tools for mechanical shaping; they are versatile systems that combine efficient molding, preservation of biological activity, and intelligent regulation.

The technological breakthroughs in these new granulators are primarily evident in the revolutionary redesign of core components and processing methods. Take the ring-die granulator, for example: it employs a dual-layer structure consisting of an inner wear-resistant alloy die and an outer temperature-regulating die. The inner layer, made of high-strength tungsten steel alloy, features an etched honeycomb microporous structure capable of compressing material to a density of 1.8 g/cm³ under 15 MPa of pressure. The outer temperature-regulating layer incorporates a graphene thermal-conduction layer; by precisely maintaining a low-temperature environment of 35–45°C, it preserves over 85% of microbial activity while keeping the powdering rate below 5%.

The deep integration of intelligent control systems endows these new machines with the ability to “think.” Equipped with IoT sensors, the granulators monitor key metrics—such as material moisture content and granule strength—in real-time and automatically adjust pressure and rotation speed. When excessive moisture is detected, the system automatically reduces extrusion speed and activates localized low-heat assistance, consuming only 10% of the energy required for traditional drying methods. Furthermore, intelligent granulators equipped with 200 internal temperature sensors can respond to and regulate temperature differentials across 12 key points within just 0.3 seconds.

From the low-temperature microbial preservation of ring-die pelleting machine and the binder-free, high-pressure molding of roller granulators to the process integration of “two-in-one” granulators, these new machines each offer unique advantages. Yet, they all share a common goal: transforming agricultural waste into high-efficiency organic fertilizer with lower energy consumption, superior quality, and enhanced biological activity. They represent not merely an upgrade in machinery and equipment, but also an indispensable “particle engine” driving the green transformation of Chinese agriculture.
