Rotary Drum Granulator
Rotary Drum Granulator
Description of rotary drum granulator:
Rotary drum agglomerator/granulator (also known as balling drums or rotary granulators) is very popular equipment that can process a wide array of materials
The equipment is typically used for high capacity applications and usually requires some type of recycle depending on the product specifications. Drum granulators are used when an agglomeration - chemical reaction process is required.
Application of rotary drum granulator:
Typical applications of a rotary drum granulator include, but are not limited to the following:
Agglomeration involving chemical reactions where the feed component(s) consist of reactive liquids or gases
The liquid and/or gas can be added into the bed of material to get a complete reaction and contain or reduce any emissions that may be generated
Many inorganic fertilizers are produced in this manner conversion of fine mineral ores into easy to handle agglomerates or balls for further processing. Iron ore, copper ore, and gold ore are a few examples.
Granulation where the only feed or the majority of the feed is a liquid or melt such as urea granulation
Coating of finished products by spraying a liquid onto the bed of material
Mixing drums that can mix multiple solids and/or liquids.
Specialty applications like a combination granulation-cooling drum.
Rotary Drum Granulating Machine/Granulator Advantages:
The cylinder body adopts special stainless steel or rubber plate lining structure. It can remove scar and peel burl automatically It has the advantages of high intensity of granule, high production, erosion proof, abrasion proof, low energy consumption, long service life, convenient operation and maintenance etc.
Working Principles of the Rotary Drum Granulator:
Raw materials to be granulated can be steam, gaseous ammonia, phosphoric acid, ammoniacal solution, ammonium phosphate slurry, and triple superphosphate slurry. After these solid fertilizer particles enter into the rotary drum, they will make reciprocating movement under functions of gravity, centrifugal force, and friction force between fertilizers. With the rotary movement of the drum, produced materials spray onto the surface of granulation nucleus. Then the coating layers become thicker and thicker until produced materials are granulated into required dimensions. Finally, those obtained products are spilled out from the discharging hole.
As the one of the key equipments in fertilizer industry, rotary drum granulator is applicable to cold, heat, and guniting and ammoniated granulation and big scale fertilizer production of high, medium and low concentration
The cylinder body adopts special stainless steel or rubber plate lining structure
It can remove scar and peel burl automatically.
