Introduction of rotary drum granulator

Rotary drum granulator is a molding machine that can manufacture materials into specific shapes. Otherwise, the barrel made of a special rubber sheet lining or acid-resistant stainless steel lining, eliminating the traditional scraper unit. Rotary drum granulator filled with steam, gaseous ammonia or phosphoric acid or nitrogen solution, phosphorus ammonia slurry, heavy calcium slurry, and then completed chemical compounding and heating compound fertilizer granulation process in the cylinder, or the cold granulation process of the compound fertilizer supplemented with a small amount of water. The material needs to granulate through the rotating motion of the cylinder and then condensed into a ball under a certain humidity and temperature to complete the ball making process.

Rotary drum granulator is a common equipment for compound fertilizer granulation. It is mainly used in the production of NPK compound fertilizer, heavy superphosphate(TSP), monoammonium phosphate(MAP), diammonium phosphate(DAP) and other products.

Working principle of rotary drum granulator

The inner part of the rotary drum granulator is composed of granulating area, blanking area, steam nozzle, annular baffle, etc. In the production of compound fertilizer, steam and ammonia are sprayed on the rolling material layer inside the barrel. The powder material is extruded and rolled through the barrel rolling, and micro-granular nuclei are formed in the barrel, which eventually agglomerate into granules. The granulation effect of drum granulator will directly affect the granulation rate and product quality of materials.

Feature of rotary drum granulator

(1) Drum granulator is one of the key equipment in compound fertilizer industry.

(2) It is suitable for hot and cold granulation and high, medium and low concentrations of mass production of compound fertilizer.

(3) The shell of the machine uses special rubber slab lining or acid-resistant stainless lining board which realizes auto scar removal and de-tumor instead of traditional drawknife equipment

(4) High balling strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, easy operation and maintenance, etc.
