分析复合肥结块原因及采取的技改措施:筛分后利用流化床冷却进一步降低包装温度;提高喷浆造粒干燥机机尾温度,降低产品的水分;增加产品分级筛网,生产1.5~2.5 mm、2.5~3.5 mm、3.5~4.5 mm 3个等级的复肥产品,提高产品粒度的均匀性;增加包膜机对复合肥进行防结块处理,提高磷矿石品位等,从而有效解决了硫基复合肥的结块问题。
Analysis of the reasons for the compost cake and technical measures taken: the use of fluidized bed after screening sieve cooling to further reduce the packaging temperature; improve jet tail granulation dryer temperature, reduce product moisture; increase the product classification sieve to produce 1.5 2.5mm, 2.5 ~ 3.5mm, 3.5 ~ 4.5mm three grades of compound fertilizer products to improve the uniformity of product size; increase the coating machine anti-caking compound fertilizer to improve the quality of phosphate rock, etc., which effectively Solve the problem of agglomeration of sulfur-based compound fertilizer.
