Frequently asked questions about the production of organic fertilizers in granulation plants

 1. Will there be recycling?
Yes. All pelletizing processes produce some degree of recovery. The amount of recycling produced depends on the selected equipment configuration. Common organic fertilizer granulators include: double-roll extrusion granulator, rotary drum granulator, disc granulator machine, new organic fertilizer granulator, new type organic fertilizer granulator, flat die granulator, ring die granulator, all kinds of granulators have their own production characteristics, and the fertilizer granulator machine price vary. Among them, for example, a disc granulator produces a lower recovery than a drum granulator.
A common misconception about pellet plant configuration is that any amount of recycling is bad. While recycling does reduce process efficiency, it is also an important part of the production process; recyclate can be used as backmix feed to reduce the moisture content of raw materials. In addition, it provides a buffer to the process, so if a disruption occurs, existing recycling resources can be used to balance things and prevent the product from being immediately affected.

2. Does the device need to be placed indoors?
When properly protected and maintained, many types of equipment can provide long-term reliable operation in outdoor environments. For example, a spin dryer is designed to operate in both indoor and outdoor environments.
However, a disc granulator is usually best placed indoors as the disc granulator is considered an "open system" and wind, rain and other elements can cause problems if the disc granulator is installed outside.

3. How fine does my material need to be ground?
A good starting point for material particle size distribution is to have all materials at minus 250 microns, although this may vary depending on the material's unique characteristics and response to agglomeration. It is also desirable to have a good particle size cross section so that when joined together, the smaller particles fill the spaces between the larger particles, creating stronger agglomerates with less void space.
