The drum granulator is a type of granulation equipment that is used to produce granular materials by rolling fine powder or granular materials in a rotating drum with the addition of a liquid binder. The drum is lined with a rubber or polyurethane coating to prevent material sticking to the surface and to reduce wear.

Application of Rotary Drum Granulator

The drum granulator is a versatile piece of equipment used for a wide range of materials including:


  • Fertilizer industry: ammonium sulfate, ammonium nitrate, urea, nitrogen, phosphorus, and potassium compounds.
  • Chemical industry: PVC resin, carbon black, potassium chloride, zinc oxide, magnesium oxide, and lead oxide.
  • Food industry: sugar, salt, and spices.
  • Pharmaceutical industry: various pharmaceutical materials.
  • Industrial byproducts: fly ash, slag, and waste materials from different industries.

Technical Features Of Rotary Drum Granulator

  1. Our drum granulator features advanced technical innovation and structural improvements, including a special rubber plate or acid-resistant stainless steel lining that automatically removes scars and eliminates the need for a traditional scraper device.

  2. With a focus on high wear resistance and easy maintenance, our drum granulator boasts high ball strength, superior appearance quality, corrosion resistance, low energy consumption, extended service life, and effortless operation and upkeep.

  3. Our drum granulator has a logical and practical layout, incorporating leading-edge technology that consumes minimal power, produces no waste discharge, and ensures stable operation. The process layout is rational and efficient, leveraging advanced technology to keep production costs low.

  4. Our drum granulator boasts a high pelletizing rate and exceptional drying efficiency, with pelletizing rates up to 70%. Our drum granulator returns only a small amount of material and can re-granulate even small particles. Plus, steam heating elevates the material temperature to achieve optimal results.


Working Principle Of Rotary Drum Granulator

The rotary drum granulator is a machine that is used to produce granular materials from raw materials. The working principle of the rotary drum granulator involves a combination of rolling and tumbling movements that result in the formation of granules.

The raw material is fed into the drum, which is lined with a rubber or polyurethane lining. The drum is then rotated, and a liquid binder is sprayed onto the raw material as it tumbles inside the drum. The liquid binder coats the particles, causing them to stick together and form small agglomerates.


As the drum rotates, it increases the size of the agglomerates by adding more raw material and binder. The rolling and tumbling motion of the drum shapes the agglomerates into spherical granules.

Then, the drum releases the granules, which can undergo further processing or serve as a final product. Adjusting the drum speed, binder application rate, and raw material particle size controls the size and shape of the granules.

In summary, the rotary drum granulator operates by combining rolling and tumbling movements, applying liquid binder, and agglomerating raw materials to form granules. This process is highly efficient and reliable, producing high-quality granular materials from a wide range of raw materials.
