Compound Fetilizer Rotary Drum Granulator Dry Mineral Powder Granulator Machine

Introduction of Rotary drum granulator
Rotary drum granulator is a kind of fertilizer granulator machine can make the material into a specific shape. Drum granulator is one of the key equipment of the compound fertilizer industry. It is suitable for large-scale production of cold &hot fertilizer granulation line and high and low concentration compound fertilizer line. Main work method for aggregate wet granulation, through a certain amount of water or steam, the basis for fertilizers in the cylinder body after full wet chemical reaction, in a certain liquid under the conditions of the rotating cylinder with campaign, reunion between particles to produce extrusion pressure of material into a ball.

The cylinder of drum granulator adopt special rubber lining or acid stainless steel plate, has realized the automatic except scar, tumor, cancel the traditional scraper device. The machine has the characteristics of high ball strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, easy operation and maintenance.

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.
