Problems solved by technology

[0003] In my country, due to the long-term application of chemical fertilizers, insufficient organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil microbial flora have been damaged to varying degrees, which has affected the safety of agricultural products to a certain extent.
The problems that may be caused by the long-term use or improper application of chemical fertilizers are: decreased quality of cultivated land, decreased yield, decreased quality, and environmental pollution
These raw materials have high cellulose content, poor self-viscosity, and high water content, resulting in difficulty in granulation and poor roundness of granules.
Due to the short storage time due to the high moisture content of the product, the produced fertilizer must be applied in a short time, otherwise it will be hardened; the roundness of the particles is poor, and it is not accepted by users from the appearance, which greatly limits the production and sales of fertilizers. ;Low capacity, high cost

Embodiment 1

[0022] As shown in the attached figure, the organic raw materials are fermented and become ecological organic fertilizers, which are measured separately with inorganic raw materials such as ammonium phosphate, general calcium, urea, and potassium chloride, and then enter the raw material conveying device. All raw materials should have good Physical properties and certain fineness; including organic raw materials, the raw materials entering the system are less than 1mm ≥ 60%; after passing through the crusher, the particle size of the material at the outlet of the crusher reaches: less than 2mm ≥ 95%; then enter the bucket elevator, and then be lifted by the bucket The machine is fed into the drum granulator, granulated by water, steam, and urine, and the material is formed in the granulator by the rotation of the body to form a fluidized bed of mechanical solid materials. During the flow of materials, extrusion and friction Under the action of the drum granulator, it will be ag...

Embodiment 2

[0032] In this embodiment, the granulation temperature is 40°C, the moisture content of the granulated material is controlled at 10%, and the drying temperature is controlled at 60°C. Other steps are identical with embodiment 1.

Embodiment 3

[0034] In this embodiment, the granulation temperature is 60°C, the moisture content of the granulation material is controlled at 5%, and the drying temperature is controlled at 80°C. Other steps are identical with embodiment 1.

Abstract

A technology problem solved by the invention is to provide a production process of organic-inorganic compound fertilizer with high pelleting rate, round appearance and low moisture. The process has the steps of: fermenting organic raw materials into ecological organic fertilizer, adding inorganic raw material into a crusher; pelleting by assistantly adding water, steam and urine after crush of thematerial in the rotary drum comminutor; pelleting continuously using the material in the disk comminutor from the rotary drum comminutor; carrying out two-stage drying for the material after pelleting, and cooling the material; sieving macrobead in the cooled material; packing the sieved product after anti-blocking treatment and then delivering them out of factory. Using the technical scheme cansufficiently play the roles of the two kinds of pelleting methods, as well as solve the problems of bad appearance quality of product, and high moisture of pelleting.

Description

technical field [0001] The invention belongs to a compound fertilizer production process. Background technique [0002] Fertilizer is an indispensable agricultural material in agricultural production. The existing fertilizers are divided into inorganic fertilizers and organic fertilizers. Inorganic fertilizers are fertilizers processed from minerals or inorganic chemical reactions. Organic fertilizers are natural humus. The production technology of inorganic fertilizer and organic fertilizer is very mature. [0003] In my country, due to the long-term application of chemical fertilizers, insufficient organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil microbial flora have been damaged to varying degrees, which has affected the safety of agricultural products to a certain extent. The problems that may be caused by long-term use or improper application of chemical f...
