挤压造粒抛圆工艺生产有机-无机复混肥

介绍挤压造粒抛圆工艺生产有机肥和有机-无机复混肥的工艺流程和工艺创新点。采用有机废弃物经好氧发酵得到的有机肥原料颗粒大，堆积密度小，宜采用三级组合抛光挤压造粒设备生产，生产的有机-无机复混肥成球率高达90％以上，强度大，成球水分低（w（H2O）不超过20％），且吨肥能耗低。

Production of organic-inorganic compound fertilizer by extruding granulation polishing circle process

The extruding granulation polishing circle process for production of organic fertilizer and organic-inorganic compound fertilizer and its innovations are introduced. The organic fertilizer raw material is obtained from organic waste by aerobic fermentation, the particle is big, the stacking density is small, through using three-level combination polishing extruding granulation equipment, the ball rate of organic-inorganic fertilizer is above 90%, the particle strength is high, the w（H2O） is less than 20%, and the energy consumption per ton product is low.
