Problems solved by technology

At present, because different raw materials need to be crushed with different particle sizes, different raw materials are usually mixed by different types of mixers, and then the crushed raw materials are mixed. In this way, not only the operation is troublesome and the cost is increased, but also the fertilizer production process, reducing production efficiency

Abstract

The invention belongs to the technical field of chemical fertilizer production, and specifically discloses a preparation method of compound fertilizer, comprising the following steps: (1) raw material preparation, using a raw material crushing and stirring device to crush and mix the solid raw material; (2) granulating, the step (1) Add the raw materials mixed in the cylinder granulator to granulate, so that the raw materials become granular compound fertilizers; (3) dry, and send the compound fertilizers processed in step (2) into the dryer Drying, the tail gas generated during the drying process is collected by the exhaust fan and mixed with steam and discharged into the cylinder granulator; (4) Screening, after the compound fertilizer is dried, it is transported into the vibrating screen to screen the compound fertilizer (5) Cooling, the qualified compound fertilizer after screening is put into the cooling mechanism for cooling; (6) Quantitative packaging, packing the granular compound fertilizer by weight. This scheme realizes the reuse of tail gas, protects the production environment and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, and in particular relates to a preparation method of compound fertilizer. Background technique [0002] Compound fertilizer is a kind of substance that provides two or more essential nutrient elements for plants, improves soil properties and improves soil fertility level, and is one of the material basis of agricultural production. When configuring compound fertilizers, the raw materials of different components need to be proportioned, and the crushed raw materials are easier to fuse. At present, because different raw materials need to be crushed with different particle sizes, different raw materials are usually mixed by different types of mixers, and then the crushed raw materials are mixed. In this way, not only the operation is troublesome and the cost is increased, but also the fertilizer production process, reducing production efficiency. Contents of the invention ...
