Rotary Drum Fertilizer Granulator Machine

Rotary drum granulator is usually used in the compound fertilizer production line.And the rotary drum granulator always be equipped with in the fertilizer production line. Its granulation production process is to send each basic fertilizer raw material into its own storage hopper, according to the requirements of formula proportions, through the computer-controlled metering and conveying equipment, and sent into the raw material crushing or secondary remixing or storage hopper, each basic fertilizer, fine material and crushed coarse granules are returned to the granulation equipment through belts for granulation. The new blended raw materials are fed into drum granulator at a uniform rate according to the balling rate. At the same time, the saturated steam is fed into the material layer as required, so that the granulation process can be granulated at a lower moisture content, which not only raises the temperature of the material, but also causes the material to be humidified, thereby reducing the drying load. But, it needs to depend on the granulation rate, if necessary, a small amount of water or fertilizer solution may be sprayed on the material to maintain the optimum liquid phase for the granulation of the material.

Rotary drum granulator Features:
1.The balling rate reaches 70%, there is a small amount of return material, at the same time, the return material size is small, and it can be re-granulated.
2. Using the steam heating, to raise the temperature of the material, that makes the material low in moisture after balling, and improve the drying efficiency.
3. Using the rubber engineering plastic as the lining, raw materials are not easy to stick the tube, and play a role in anti-corrosion insulation.
4. It has the larger output, the less power consumption, and the lower maintenance costs.
