The utility model provides a slurry pump for producing fertilizer, comprising a centrifugal pump I and a slurry pond I, wherein the slurry pond I contains slurries; and the centrifugal pump I is directly inserted in the slurry pond I. The slurry pump is characterized in that a centrifugal pump II and a slurry pond II are added, wherein the slurry pond II contains no slurries; and an inlet of the centrifugal pump II is communicated with the slurry pond I by a pipeline. The slurry pump overcomes the defect that the water is difficult to control by the existing slurry pump in the process of producing fertilizers. In the utility model, the slurry pump is changed from a suction type into a guide type; the slurry flows in the centrifugal pump II from a pipeline between the slurry pond I and the inlet of the centrifugal pump II and is pumped up by the work of the centrifugal pump II; the existing water control index 30 is adjusted as 27.5; furthermore, a milling machine and production output are not affected; and th
