转鼓造粒机是复合(混)肥生产的关键设备之一,它的作用是使粉状物料在筒体内进行预造粒,形成粒径1～2 mm的微小颗粒。转鼓造粒机的造粒效果将直接影响成球率和产品质量。1传统转鼓造粒机结构传统的转鼓造粒机筒体结构大多是采用单一直径,筒体内加设挡料环(见图1)。从设计和制造 Drum granulator is one of the key equipment for compound (mixed) fertilizer production. Its role is to pre-pelletize the powder material in the cylinder to form tiny particles with the diameter of 1 ~ 2 mm. Drum granulation machine granulation effect will have a direct impact on the ball rate and product quality. A traditional drum granulator structure Traditional drum granulator cylinder structure are mostly single diameter, the cylinder body to add a stop ring (see Figure 1). From design and manufacture
