The granulation process of organic fertilizer plays a significant role in the production of organic fertilizer, directly affecting the roundness, uniformity, and fertilizer retention and water retention performance of organic fertilizer particles. So, what are the differences in the several processes of organic fertilizer granulation equipment? What impact does it have on product quality? Firstly, lets take a look at the advantages of each device and select a granulator as a reference for you.

Roll squeezing granulator

The roller extrusion granulator belongs to dry granulation, which does not require drying process, has high particle density, good fertilizer efficiency, and full organic matter content. Saved the cost of purchasing dryers and coolers, eliminating the need for coal burning in the later stage, which can save a significant amount of funds. However, the granulation shape of the extrusion granulator is flat and circular, which makes it easy to get stuck when sowing crops in the field, and the flowability is not very good. Therefore, if it is organic fertilizer produced by machine sowing farmers, this granulation process should be used with caution, and it is recommended to choose compound fertilizer and mixed fertilizer.

Rotary Drum Granulator

The conversion granulator is a process for granulating compound fertilizers and can also be used to produce organic fertilizers, but with a low granulation rate, it can produce various fertilizers.

Disc Pelletizer

The disc granulator is a more traditional granulation process. I personally recommend this type of granulator, which has smooth granulation, good sales, low equipment price, but the disadvantage is low density. At present, people are pursuing new granulation methods, so the number of users using them is decreasing.

Stir toothed organic fertilizer granulator

The toothed organic fertilizer granulator is currently a popular product in the market and widely loved by customers. If an organic fertilizer throwing machine is added, the process has a high yield, and the processing and granulation can be comparable to disc granulation. But you need to purchase a dryer and cooler. Therefore, the price of the entire device is higher.

Ring mold granulator

The particle density of the ring mold granulator is higher than other equipment, and the particles will not scatter during sales and transportation. However, in the later stage, a rounding machine is needed to achieve full and round particles, and this granulation process is more expensive.
