Recently, a disc granulation organic fertilizer production line with an annual capacity of 30,000 tons, constructed by Huaqiang Heavy Industry, entered the installation and commissioning phase at a client’s facility in Shanxi. Inside the spacious steel-structure workshop, the main equipment—painted in a distinctive blue-green—is arranged alongside yellow safety guardrails. Key components such as the automatic batching system, chain crusher, double shaft paddle mixer, disc granulator, dryer, cooler, drum screener, packaging machine, and multiple belt conveyors have been positioned, clearly revealing the production line’s process layout.
Utilizing agricultural waste—such as livestock manure and crop straw—as raw materials, the process begins with fermentation and decomposition. The materials are finely crushed by a chain crusher, precisely proportioned via the automatic batching system, thoroughly mixed in the twin-shaft paddle mixer, and then fed into the disc granulator to be rolled into spherical granules. After classification by the rotary screen, the wet granules undergo dehydration in the dryer and cooling in the cooler; qualified products are then weighed and sealed by the packaging machine. The entire process is linked by belt conveyors, ensuring a high degree of automation with minimal manual intervention.
The disc granulator serves as the core equipment; through disc rotation and tilt angle adjustment, materials naturally form into spheres. This method yields a high granulation rate and produces round, uniform granules, making it particularly well-suited for organic fertilizer raw materials characterized by high viscosity and fluctuating moisture content. To address the specific operating conditions in Shanxi—namely low winter temperatures and high raw material moisture—Huaqiang Heavy Industry optimized the drying system’s thermal efficiency and insulation thickness, ensuring stable output of the 30,000-ton annual capacity even in cold environments.
With years of expertise in the fertilizer equipment sector, Huaqiang Heavy Industry consistently provides customized services covering the entire process, from raw material characteristics to finished product standards. The successful implementation of this Shanxi project reaffirms the company’s comprehensive capabilities in the design, manufacturing, and installation of organic fertilizer production lines. Once operational, the project will effectively promote the resource utilization of local agricultural waste and provide robust equipment support for the development of green agriculture.
