A: Huaqiang Heavy Industry’s complete organic fertilizer production line follows a standardized process flow and comprises five core units: fermentation, pre-treatment, granulation (forming), finishing, and packaging. It accommodates the production of both powdered and granular organic fertilizers, supports customized production capacities ranging from 10,000 to 500,000 tons, and meets requirements for automated production and eco-friendly dust control.

First is the fermentation and composting equipment—the core of the line—which includes trough-type and large wheel compost turners, paired with conveyors and biological deodorization systems. These enable the aerobic composting of raw materials such as livestock manure, crop straw, and sludge. Fermentation is completed in just 7–10 days, offering a short cycle and low energy consumption, while adapting to various facility layouts.
Next is the pre-treatment equipment, featuring semi-wet material crushers, automatic batching machines, and double-shaft paddle mixers. The crushers efficiently process high-moisture, high-fiber fermented materials without clogging; the batching machines ensure precise mixing ratios of raw materials and additives, while the mixers guarantee uniform blending, laying a solid foundation for subsequent processing.
The granulation stage features key forming equipment, including new type organic fertilizer granulators, disc granulators, and rotary drum granulators. Disc granulation making it energy-efficient and ideal for small-to-medium production lines, whereas rotary drum granulation offers high capacity, making it suitable for large-scale organic fertilizer plants.
Subsequent finishing equipment includes drum dryers, coolers, screening machines, and coating machines. These effectively control fertilizer moisture content, screen for qualified granules, and improve granule roundness and anti-caking properties. Finally, fully automatic packaging machines handle weighing, sealing, and palletizing, ensuring a fully automated workflow.
In addition, the entire system is equipped with comprehensive conveying, dust removal, and electrical control systems. Huaqiang Heavy Industry offers customized equipment configurations based on client-specific factors—such as raw material types, site dimensions, budget, and desired product form—providing a one-stop, turnkey plant construction solution.
