Disc granulator (also known as pelletizing disc, disc granulator), with simple structure, low cost, convenient maintenance and other characteristics, granulation principle is the same as the rolling round night in southern China, the basic physics in the pulverizer respectively crushed, metered in the mixer mixed well, there is a belt conveyor transmitted to the top of the disc, continuous quantitatively added to the shallow disk, the raw materials in the shallow plate have sprayed down the adhesive bonding, wrapped into granules, with the rotation of the disc in the disc tumbling, gradually increasing.

 

How to manufacturer granular fertilizer with d disc pelletizer? Due to the ability of the disc to automatically classify during rotation, large particles float on top and are continuously unloaded from under the disc, while small particles continue to bond with the newly added material in the disc and tumble until they are discharged. Disc granulator is more used in the production of compound fertilizer, which greatly affects the production efficiency of the entire compound fertilizer production line. Now although the output of the disc granulator is not low, people have the habit of going high, so the requirements for products will be higher and higher, which is also humanized. Therefore, how to improve the production efficiency of the disc granulator should be very important for fertilizer production plant.

 

The main ways to increase the yield of disc granulators are:

 

First, according to the composition, fineness, viscosity, humidity, temperature and other characteristics of the powder, the water content of the powder is controlled at about 30-28%. You can use a manure dewatering screw press to dry your animal manure.

 

1, the water content is too large, too many balls, the surface of the ball is very sticky, easy to block the surface of the screen;

 

2, how to initially determine the volume of granular water in the granulation manufacturing process: the simplest and practical method – hand feeling method: grab a material ball from the disc granulator, the hand can be a ball, with the finger touch can be released. In this way, there are many particles, the yield is high, and it is not easy to clog the screen surface.

 

Second, strictly control the quality of various raw materials such as fertilizers in strict accordance with the compound fertilizer technology.

1. It is strictly forbidden to use iron blocks, stones larger than 10mm, and wooden blocks larger than 10mm. The quality indicators of rice bran and rice sand are also not many, which seriously affects the yield.

 

2. The particle size of the powder used as compound fertilizer is 70-90 mesh.

 

3. Do a good job in technical training to improve the technical quality and operational skills of workers in conversion of organic waste to organic fertiliser.

 

Third, when selecting a nozzle, it is necessary to grasp the working mechanism of the nozzle: according to the theory of fluid mechanics, it is proved that the greater the pressure, the smaller the through hole, and the larger the droplet diffusion surface. At the same pressure, the nozzle has a small nozzle and a small droplet density; the nozzle is large and the droplet density is large.

 

1. The smaller the size of the feed droplet (or larger), the lower the yield (or higher).

 

2. The denser the feed droplets (or the thinner), the more (or less) the amount of feed liquid, and the higher (or lower) of the discharge.

 

3. In general, B-type spherical spiral or B1 type basic spiral nozzle is the best choice for disc feeder.

 

Good blade, the particle size is uniform and beautiful, the blade material must be 16m, the blade is divided into two pieces, and there is no gap between the two blades.
