Description
product details
The Rotary Drum Granulator is a fundamental piece of equipment in the compound fertilizer industry, designed for large-scale production of uniformly shaped granules. This robust machine utilizes the wet granulation method (agglomeration) to transform powdered raw materials into durable, spherical particles. It is highly versatile, capable of processing both cold and hot materials and producing fertilizers with a wide range of nutrient concentrations. The process involves introducing a controlled amount of water or steam into the rotating drum, which creates the ideal liquid phase for chemical reactions and causes fine particles to adhere and grow into granules through a tumbling and compaction action.
Introduction to the Features of the Drum Granulator
High-Capacity Production:
Benefit: Engineered for continuous, large-scale operation, making it the most efficient solution for meeting high output demands in major fertilizer production facilities.
Exceptional Granule Uniformity & Strength:
Benefit: The tumbling action inside the rotating drum produces strong, spherical granules with a consistent size distribution. This results in improved product appearance, easier packaging, storage, and application, and reduced dust.
Proven Wet Agglomeration Process:
Benefit: By carefully controlling the addition of liquid binders (water/steam), it facilitates necessary chemical reactions and promotes efficient particle-size growth, ensuring high granulation yield and product quality.
Unmatched Process Versatility:
Benefit: Successfully handles a broad spectrum of raw material formulations for low, medium, and high-concentration compound fertilizers, supporting both cold and hot granulation processes with minimal adjustments.
Robust & Reliable Design:
Benefit: Built with a heavy-duty drum, reliable drive system, and durable internal liners to withstand continuous operation in a corrosive environment, ensuring long service life and minimal downtime.

Frequently Asked Questions (FAQ)
Q: What is the typical granulation yield (efficiency) of this machine?
A: The granulation yield is generally very high, often exceeding 90%. The exact figure depends on the raw material characteristics, binder selection, and process parameter optimization.
Q: How is the drum speed controlled, and why is it important?
A: The drum speed is typically adjustable via a variable frequency drive (VFD). Precise speed control is critical as it directly affects the material retention time and the tumbling action, which are key factors in determining granule size and density.
Q: Can it handle the granulation of organic-based fertilizers?
A: Yes, it can process organic or organic-inorganic blends. However, the fibrous nature of some organic materials may require recipe and process adjustments, and potentially the addition of specialized binders, to achieve optimal results.
