Drum granulators play a vital role in modern fertilizer production—transforming mixed powdered raw materials into uniform, highly efficient fertilizer granules. However, few realize that this process involves a complex and coordinated system of equipment.
Drum granulators use the centrifugal force of a rotating drum to cause the wet powdered material to tumble and agglomerate within the drum, gradually forming uniform granules. This seemingly simple process is based on sophisticated engineering principles:
Precisely angled design ensures that the material passes through the granulation zone at an optimal speed.
Scientific internal structure – The lifting plate design promotes thorough tumbling and mixing of the material.
Controllable liquid phase system – Precisely control the binder addition amount and distribution uniformity.
Wear-resistant materials – Special stainless steel or anti-corrosion treatment extends equipment life.
“A high-quality drum granulator requires not only a sturdy structure but also a sophisticated control system. Our equipment uses variable frequency speed regulation technology, which allows for speed adjustments based on different formulations, ensuring that each batch of product achieves the ideal granule strength and uniformity.”
Although the drum granulator is critical, it is only one link in the fertilizer production line. Producing high-quality granular fertilizer requires the precise coordination of a series of equipment.
Pre-processing equipment
Fertilizer crusher – Removes clumped raw materials and ensures uniform particle size
Batching system – Accurately measures various raw materials to ensure formulation accuracy
Mixer – Thoroughly mixes raw materials to prepare for granulation
Post-processing equipment
Dryer – Reduces granule moisture and improves stability
Cooler – Rapidly cools granules to prevent clumping
Screener – Separates qualified and unqualified granules to ensure product consistency
Coating machine – Adds a protective layer to improve fertilizer performance
Packaging machine – Automates packaging to improve production efficiency
When a granulator works in conjunction with a precise batching system, efficient drying equipment, and an intelligent screening system, efficient, stable, and high-quality fertilizer production can be achieved.
