Abstract: The production technology of suspended liquid fertilizer was summarized. In view of the problems of slow production rhythm, tedious production process and waste of ingredients in the existing liquid fertilizer production equipment, a suspended liquid fertilizer production technology and integrated equipment which combined mixing formula material and producing fertilizer together were designed. And the structure and advantages of the integrated machine for suspended liquid fertilizer production were also introduced. The production practice had proved that the suspension liquid fertilizer production process has the advantages of high accuracy, stable and reliable performance, is simple to operation, economical application.
