Raw Material Pretreatment and Fermentation/Turning: High-moisture organic materials (such as livestock manure) require moisture adjustment and pretreatment. A half-wet material crusher can process fermented, matured material with a moisture content of ≤30%, breaking down compacted, decomposed material to a fineness of ≥60 mesh to provide suitable powder for subsequent granulation. During the fermentation stage, a double-screw compost turner—featuring a counter-rotating dual-shaft design—can achieve a turning depth of 1.6 meters and a width of 12 meters. It simultaneously performs turning, mixing, and oxygenation, shortening the fermentation cycle by 20%–30%; the machine is stable in operation and capable of servicing multiple fermentation channels.
Diverse Options for Wet Granulation: For organic materials with high moisture content and high viscosity, the "new type organic fertilizer granulator" and the "new type two-in-one organic fertilizer granulator" offer expanded possibilities. The two-in-one model integrates mixing and granulation functions, allowing a single machine to complete both processes and thereby saving on floor space and investment costs. The disc granulator is a classic piece of wet granulation equipment; by adjusting the disc inclination angle (35°–55°) and rotation speed (11–20 rpm), it achieves a pelletizing rate of over 93%, producing granules with excellent sphericity and a smooth, round appearance. For dry powder materials, the organic fertilizer dry granulator utilizes physical compression molding—eliminating the need for added water—making it ideal for moisture-sensitive formulations. The complete disc granulation production line integrates crushing, mixing, granulating, screening, and packaging processes; it is well-suited for small-to-medium-scale production, offering intuitive operation and easy maintenance.
Selection Recommendations: Choose a double-roller extrusion granulation line if raw materials have low moisture content, high granule strength is required, and energy consumption needs to be minimized. Opt for a disc granulation production line if raw materials have high moisture content, superior granule appearance is desired, and the scale is small-to-medium. Select the new "two-in-one" organic fertilizer granulator if handling diverse materials and prioritizing equipment integration. Conducting a trial run with raw materials prior to selection is recommended to ensure a precise and successful investment.
