目前团粒法生产复混肥的中小型企业 ,大部分采用高温烟道气与物料在回转式烘干机中顺流接触进行烘干处理。烘干机进料溜槽底部正对燃炉高温进气口 ,溜槽底及两侧经常被烧坏 ,生产低浓度复肥时 ,由于烘干温度相对较高 ,一般 1～ 2个月即被烧通 ,而高浓度复肥由于烘干温度较低 ,
At present, the production of compound fertilizer by the pellet method for small and medium enterprises, most of the use of high temperature flue gas and materials in the rotary dryer downstream contact drying. The bottom of the feed chute of the dryer is facing the high-temperature gas inlet of the burner and the bottom and sides of the chute are often burned. When the low-concentration compound fertilizer is produced, the drying temperature is relatively high due to the relatively high drying temperature and is generally burnt in 1 to 2 months Pass, and the high concentration of compound fertilizer due to lower drying temperature,
