The drum type fertilizer granulator is often used for large scale NPK granulation plant. On the one hand, this machine has a large capacity. When using this machine, it can make into 30t quality NPK fertilizer pellets within one hour. Moreover, the granulation rate of rotary drum pelleting machine can reach 85%, which means that it can improve the granulation efficiency to a large extent. On the other hand, the rotary drum making granules machine is adaptive for mass production of cold, hot cold and high-medium-low concentration compound fertilizer. Therefore, When you have demands of large NPK granular fertilizer production, this machine is your best choice. It is worth mentioning that our engineers employed the rubber plastics materials on the internal of steam drum granulation machine. This way can prolong this machine service life, meanwhile, the NPK fertilizer materials are not easy to stick to the cylinder.
