How Disc Granulator Works To Make Fertilizer Pellets

The disc granulator has the characteristics of high granulation rate, simple layout, favorable price and convenient maintenance. After the material is crushed in the pulverizer and mixed in the mixer after being metered, it is conveyed by the belt conveyor to the top of the disc granulator, and then fed into the disc in a quantitative manner. The material in the disc is bonded by the sprayed adhesive, wrapped into granules, and rolled in the disc with the transformation of the disc and gradually grows up. Because the disk has the ability to automatically classify during rotating, the large particles float on the top and are discharged one after another from the bottom of the disk, and the small particles continue to bond with the newly added material in the disk and roll and grow. until removed.

The inclination of the disc must not be less than the natural angle of repose of the mixture, otherwise the material will stick to the chassis and rotate with the disc. Usually 45° is the original inclination value. It can be adjusted between 45°- 60° as required. The commonly used binder for disc granulation is sulfuric acid or phosphoric acid. The concentration of sulfuric acid is usually 50%. The amount used is about 50ks of 98% sulfuric acid for each ton of fertilizer pellets manufacturing.
The disc granulator consists of a tray and a support frame with adjustable inclination and rotation speed. The quality of disc granulation mainly depends on the description and operation of the disc granulator, such as the inclination angle of the granulator, the rotation speed, the diameter of the disc, the concentration of the binder, the dosage, the feeding and discharging method, etc. Usually the diameter of the disc is 1.6-22m, the inclination angle is 45°-60°, and the rotation speed is 28r/min


The granulation of the disc granulator is very uniform, the return material is very low, and the production capacity is large. A disc granulator can produce 1-6 tons of products per hour. The disadvantage is that the material cannot be pretreated, and the dust and smoke pollution is more serious, which is mainly due to the relatively large opening of its own.

Why Disc Granulation Line Is Recommended In Fertilizer Making

How does the disc granulation line granulate organic fertilizer? With the development of environmental protection and organic agriculture, the use of organic waste to produce organic fertilizer through biological fermentation has developed rapidly in my country, making organic waste treatment and sale of harmless and resourceful change. However, most of the organic fertilizers obtained by biological fermentation are coarse powder or irregular small pieces, which are very inconvenient to use, especially unfavorable for large-area machine spreading.

Spherical granular organic fertilizer making from the coarse powder or irregular small block organic fertilizer obtained by biological fermentation is the key to solve the problem of promoting the use of organic fertilizer in large areas. At the same time, in order to avoid uneven fertilizer effect when making grains , these raw materials will be crushed, stirred, and added with NPK, etc., which can not only increase the nutrients of organic fertilizers, but also distribute these nutrients evenly and consistently to each particle; Here, SX pan granulation line can perfectly finish the above processes.

Next, I will explain to you how to compress and granulate organic fertilizers: the coarse powder or irregular small pieces of organic fertilizer after biological fermentation are characterized by high moisture (30~40%), loose The bulk density is 0.3~0.4t/m3), and there are many fibers. The existing coarse powder or irregular small block organic fertilizer after biological fermentation is made into spherical granules. Click here to learn more

Pan Granules Production Line Technology:

First of all, these organic fertilizers are decomposed into small molecular substances that can be directly absorbed and utilized by plants. During the fermentation period, the organic fertilizer fermentation machine needs to be continuously turned over to avoid insufficient supply of internal oxygen, and even produce anaerobic reaction to affect the rate of decomposing; the decomposing is completed. After that, the organic materials and the medium and trace elements to be added are pulverized evenly, and then sent to the automatic batching system.

There is a conveyor belt under the batching system to transport the material to the horizontal mixer at a uniform speed, and then enter the next granulation link after mixing evenly;

The use of fertilizer disc granulation making machine to condense chemical components and organic fertilizers can avoid nutrient differentiation in the later transportation process. At the same time, granulated fertilizer is more conducive to storage and transportation, which is also in line with the future development trend of fertilizer market and is suitable for mechanized fertilization; granulation After that, drying and cooling are carried out, so as to link packaging and transportation to realize automatic continuous production. After the granulation process is completed, the new fertilizer manufacturers can carry out screening, coating and other processes according to their own needs to further improve the economic value of commodities.
