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 particularly discloses a compound fertilizer preparation method. The method comprises the following steps that 1, raw materials are prepared, wherein solid raw materials are crushed and mixed by means of a raw material crushing and stirring device; 2, granulating is conducted, wherein the raw materials mixed in step 1 are added in a cylinder granulator, and the raw materials become granular compound fertilizer; 3, drying is conducted, wherein the compound fertilizer processed in step 2 is sent into a dryer to be dried, tail gas generated in the drying process is collected through an exhaust fan, and the tail gas and steam are mixed and discharged into the cylinder granulator; 4, screening is conducted, wherein the compound fertilizer is dried and then delivered into a vibrating screen to screen the compound fertilizer; 5, cooling is conducted, wherein the qualified compound fertilizer obtained through screening is put into a cooling mechanism to be cooled; 6, quantitative packaging is conducted, wherein the granular compound fertilizer is packaged by weight. According to the scheme, recycling of thetail gas is achieved, the production environment is protected, and the cost is lowered.

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 ...
