Introduction of Drum granulator:
Drum granulator is one of the key equipment of compound fertilizer industry, and this type granulator is suitable for cold and hot granulation and high and low concentration of compound fertilizer production on a large scale. This machine cylinder, with a special jointing sheet lined with or acid stainless steel lining board, has realized automatic scar removal to take off the tumor, and canceled the traditional scraper. The granulator machine has the features of high strength into the ball, good appearance and quality, corrosion resistance, resistance to wear, low-energy consumption, long service life, convenient operation and maintenance, etc.
The main features of Drum Granulator:
(1)Rate of ball-becoming up to 70%, have a small amount of returned material, expected, small granularity of returned material, can be re-granulation.
(2)Steam heating, improve material's temperature, so that have lower moisture when material change into the ball, improve dryness efficiency.
(3)Use rubber plastic for lining, raw materials difficult to stick cylinder, and played the role of anti-corrosion, keep warm.
(4)High yield, little power consumption, low maintenance costs.
Working Principle of the Drum Granulator:
The main working method is aggregate wet granulation. Through a certain amount of water or steam, basic fertilizer mix wet in tube body after the full chemical reaction. Under a certain liquid conditions, in virtue of rotary exercise of the rotating cylinder, so that material particles have a extrusion stress, reunite to ball.
Drum granulator Applications:
1.Sludge drum granulation process
2. Sludge organic and inorganic fertilizers drum granulation process
3. Livestock manure organic drum granulation process
4. Industrial waste organic fertilizer drum granulation process
5. Compound fertilizer steam drum granulating process
