Shanxi Province boasts abundant agricultural and livestock resources, with large-scale cattle and sheep farms generating significant amounts of manure. To thoroughly address the problems of manure accumulation, pollution, and resource waste, local agricultural technology companies invested in the construction of a standardized organic fertilizer production base. On June 12, 2025, the complete 30,000-ton/year disc granulator organic fertilizer production line undertaken by our company successfully completed all on-site installation, integrated commissioning, and trial production with materials, and officially commenced production.

This project is a standardized, fully automated granular organic fertilizer production line. Its core configuration is a Φ3000 high-efficiency disc granulator, a mainstay model suitable for large-scale mass production. The disc height and tilt angle are electrically and intelligently adjustable, and it is equipped with a high-pressure humidification and atomization system. Targeting the characteristics of locally fermented cow and sheep manure and straw mixtures, the equipment achieves a stable granulation rate of ≥85%, with finished granules concentrated in the 2-4mm range. The granules are dense, round, and have high compressive strength, completely solving the problems of excessive powder and uneven particle size associated with traditional granulation methods. The production line is designed to produce 5-6 tons per hour, with a stable annual capacity of up to 30,000 tons at full load.

The entire production line is equipped with a fully automatic four-bin batching machine, a 7.5kW high-power twin-shaft mixer, a drum dryer and cooler, multi-layer grading and screening equipment, and a fully automatic quantitative packaging machine, all under centralized PLC frequency conversion control. The on-site construction adopts a standardized assembly line layout with reasonable equipment spacing and smooth conveying, suitable for the regular factory conditions. Considering the dry and windy climate of Shanxi, dustproof protective devices have been added to the core transmission and granulation parts of the equipment, and wear-resistant parts have been upgraded and thickened to effectively extend the service life of the equipment.

Our technical team is on-site to complete equipment hoisting and alignment, wiring layout, and parameter calibration. They optimized the granulation speed and humidification parameters based on the local raw material moisture content and fiber ratio, and provided comprehensive training to operators on equipment maintenance, troubleshooting, and process adjustment. After commissioning, the finished product moisture content is ≤14%, and the organic matter content meets the national standards for commercial organic fertilizer, which is widely used in the local grain, fruit tree, and medicinal herb planting industries.
