High Output Wet Type Rotary Drum Granulator Organic Compound Fertilizer Granulator Machine for Production Line

The rotary drum granulator is a professional continuous wet granulation machine engineered specifically for large and medium organic and compound fertilizer production lines. Unlike disc granulators, it utilizes a horizontal rotary drum structure to achieve high-capacity continuous rolling granulation. Powdered raw materials are processed into round, uniform fertilizer pellets through continuous rolling, extrusion, and bonding inside the rotating drum.

With a thickened anti-corrosion drum body, a reinforced transmission system, and stable supporting rollers, the machine operates continuously for 24 hours with a low failure rate. It supports mass production and serves as the core molding equipment for standardized commercial fertilizer factories. The finished pellets feature high strength, excellent roundness, and resistance to breakage, significantly improving fertilizer quality and market competitiveness.

• Large Continuous Output: The horizontal drum rolling structure enables uninterrupted feeding and granulation, making it suitable for large-scale fertilizer production with a much higher capacity than disc granulators.
• High Pellet Strength & Roundness: Materials form dense pellets through long-distance rolling and extrusion inside the drum. Finished pellets are smooth, hard, and resistant to loosening or breaking.
• Anti-corrosion & Wear-resistant Design: The inner drum body is treated with an anti-corrosion and wear-resistant lining, effectively preventing material corrosion and extending equipment service life.
• Stable Continuous Operation: Equipped with a heavy-duty reducer and a stable support roller system, the machine runs smoothly with low noise and can operate continuously for extended periods.
• High Forming Rate: Reasonable drum speed and an internal material lifting structure ensure uniform material rolling, achieving a granulation forming rate of 85% and above.
• Wide Raw Material Adaptability: Suitable for various organic and inorganic powder materials with no strict requirement on material fineness, offering strong production compatibility.
• Easy Maintenance: The integral assembly structure facilitates daily inspection, lubrication, and replacement of wearing parts, resulting in low long-term operating costs.

The rotary drum granulator is widely used in commercial large-scale fertilizer production projects. It is the core equipment for organic fertilizer, compound fertilizer, bio-fertilizer, and humic acid fertilizer production lines. It can process chicken manure, cow manure, sheep manure, compost materials, straw powder, sludge, NPK powder, and other organic and inorganic raw materials.

It is especially suitable for medium and large fertilizer factories with daily output ranging from tens of tons to hundreds of tons, enabling standardized, mass, and industrial fertilizer production. The finished granules are widely used in farmland planting, fruit trees, vegetables, and commercial agricultural planting bases.

The rotary drum granulator adopts the wet rolling agglomeration granulation principle. After the powdered raw materials are evenly mixed with an appropriate amount of water or liquid binder, they are continuously fed into the rotating granulation drum.

As the drum body rotates slowly, the internal material lifting plate lifts and drops the materials repeatedly. Under the action of gravity, centrifugal force, and mutual extrusion between materials, the fine powder gradually gathers, rolls, and bonds into small spherical particles. These small particles continue to wrap fine powder during continuous rolling, gradually growing into uniform and dense standard fertilizer pellets.

The entire granulation process is continuous and stable. After granulation, the qualified pellets are discharged evenly and enter the next drying, cooling, and screening process to complete the full fertilizer production procedure.
