Abstract

The invention discloses an extrusion granulation processing method of an organic fertilizer. The extrusion granulation processing method comprises the following steps: A, weighing raw materials through a weighing system, and conveying the raw materials into a mixing bin through a belt conveyor or an elevator; B, uniformly turning and mixing the raw materials by a stirring and turning mechanism inthe mixing bin; C, discharging the turned and mixed raw materials into a crusher for primary crushing to obtain crushed raw materials, and performing primary sieving on the crushed raw materials to obtain a first sieved material and sieved residues; D, adding the sieved residues into a grinding machine for grinding, and performing secondary sieving to obtain a secondary sieved material; and E, mixing the primary sieved material and the secondary sieved material, and conveying the raw materials into a mixing bin granulator through a belt conveyor or an elevator for extrusion granulation. The processing method adopted by the invention is simple to operate, can realize rapid extrusion granulation of the organic fertilizer, and has the advantages of good particle uniformity and low processingcost.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer processing, in particular to an extrusion granulation processing method of organic fertilizer. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals, and are applied to the soil to provide plant nutrition as carbon-containing materials whose main function is. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food pr...
