Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a granulating device for producing agricultural compound fertilizers. Background Art

[0002] With the growth of the global population and the increasing requirements for agricultural product output and quality, agricultural production is increasingly dependent on compound fertilizers. Compound fertilizers can simultaneously provide multiple nutrients required for plant growth, such as nitrogen, phosphorus, potassium and various trace elements, which is beneficial to improving the yield and quality of crops. In order to meet the needs of large-scale agricultural production, the production scale of compound fertilizers is constantly expanding, which requires efficient production equipment to ensure its output. Modern agriculture not only focuses on the nutrient content of fertilizers, but also has high requirements for the physical properties of fertilizers, such as particle size, particle strength, and fluidity. Uniform particle size can ensure uniform distribution of fertilizers during fertilization, avoiding the adverse effects of localized excessive or insufficient nutrients on crops; good particle strength can reduce the breakage and pulverization of fertilizers during transportation, storage and application; excellent fluidity is conducive to the smooth transportation of fertilizers in fertilization equipment. These quality requirements have prompted compound fertilizer manufacturers to seek more suitable granulation equipment to produce products that meet standards.

[0003] However, during the disc granulation process, the rolling and agglomeration of materials in the disc are affected by many factors, such as the disc rotation speed, the material placement position, etc., which may lead to uneven particle size. Some particles may be too large or too small, affecting product quality and subsequent use effects.

[0004] Therefore, we provide a granulating device for producing agricultural compound fertilizer to solve the above problems. Utility Model Content
