The main working method of rotary granulator is aggregate wet granulation. Through a certain amount of water or steam, basically the fertilizer mixing 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.the rotary fertilizer granulator is one of the key fertilizer production line 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 rotary granulator 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 rotary 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 Rotary 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)the rotary granulator use rubber plastic for lining, raw materials difficult to stick cylinder, and played the role of anti-corrosion, keep warm.
(4)the rotary granulator has high yield, little power consumption, low maintenance costs.
