The working principle of the disc granulator in the fertilizer production line

fertilizer granulator Nov 19, 2019

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.

5, high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.

Fertilizer granulator machine is the core equipment for fertilizer manufacturing process. As one of leading fertilizer machine manufacturers in China, in addition to the disc granulator, we also produce other types of fertilizer granulator machines, and other equipment such as compost turning machines, mixer machine, crusher machine, etc.

The technology of organic and inorganic fertilizer production

The inorganic non-chemical produced by chemical method has the advantages of high nutrient content, fast fertilizer efficiency, convenient storage and transportation, and convenient application. Organic-inorganic compound fertilizers are not a simple blend of organic and inorganic fertilizers. In order to produce organic-inorganic compound fertilizer stably and efficiency, it is necessary to solve the granulation property of the mixture. The organic fertilizer production line is mainly divided into two major steps: one is the fermentation of organic matter; the other is the mixing of organic fertilizer and inorganic fertilizer after fermentation. The materials that need to be deal with organic fertilizer include poultry manure, wheat straw, rice husked. These materials are needed to be broken first, and the livestock manure must be fermented in order to move out the odor. The fermented organic fertilizer is mixed with inorganic fertilizer to granulate.

The fertilizer granulating production:
Making the raw material aftermentating by using the fermentation compost turner machine put into the fertilizer mixer machine to mix and then add some N,P,K, to fermentation again. After that making the material to be dried using the drum dryer and then enter the fertilizer granulator to make fertilizer granules. At the time the temperature is high and we need to use the drum dryer to dry the water to the requirement of producing the organic-inorganic fertilizer granules. After cooling ,using the drum screening machine to separate the fertilizer granules which don’t meet the requirements of the fertilizer size and make them into the fertilizer granulator machine to be granulated again.
