How to control the particle size of fertilizer using a disc granulator machine?

2022/12/23

 What is a pan granulator?The disc granulator machine is a kind of granulator. You can use the disc granulator machine to form a complete fertilizer production line with other fertilizer equipment. It is generally suitable for granular fertilizers such as organic fertilizer production process, npk production line and bio organic fertilizer production. It is not only durable, but also has the advantages of uniform granulation and high granulation rate. Our granulation disc adopts an overall arc structure, and the granulation rate can reach more than 93%. It relies on a rotating pan to granulate fertilizer granules. And can clearly see the granulation process, and adjust in time according to the granulation situation. The particle size is controllable and the investment is low.

How to control the size of fertilizer particles using a disc granulator machine?
There are many factors affecting particle size, among which the most influential ones are disc inclination, disc rotation speed, scraper position and raw material moisture content, etc. Controls the inclination of the disc.
1. The inclination angle between the disc and the ground is one of the main factors affecting the particle size. Generally, the greater the angle of inclination between the granulation plate and the ground, the smaller the granules produced. The appropriate inclination angle is 50-60 degrees. You can choose a suitable angle to install the disc granulator according to the required particle size.
Adjust the moisture content of the raw material.
2. The moisture content of the material will also affect the particle size. If the raw material is too dry, it will be difficult to form granules during the granulation process. If the moisture content of the raw material is too high, the resulting particles will be too large. Therefore, when using the disc pelletizer, the moisture content of the raw materials must first be adjusted to keep the moisture content at an appropriate level.
3. The position of the scraper is correct. In the disc granulator, we installed a scraper to prevent the raw material from sticking to the granulation disc. You can adjust the scraper to get it in the right position, which can help you get the right size granulated fertilizer.
