New type organic fertilizer granulators are more flexible than traditional models. Whether it's straw, manure, mushroom residue, or distiller's grains, they can be adapted with minimal adjustments without having to replace equipment.
If using fermented straw for granulation, this raw material is fibrous and somewhat loose, making it difficult to produce compact pellets. Add 5%-8% bentonite (a common binder) to the raw material, mix it thoroughly before feeding it into the new type organic fertilizer granulator, and increase the roller pressure. This will ensure compact pellets without breaking them up and damaging the organic matter in the straw.
For wet, sticky raw materials like chicken manure and pig manure, the biggest concern is clogging the granulator. Instead of adding too much binder, add about 10% dry mushroom residue to reduce moisture. Also, slow the new type organic fertilizer granulator's feed rate to allow the raw material to fully form in the granulation chamber. The resulting pellets are smooth and less likely to stick to the machine.
When it comes to fine raw materials such as mushroom residue and wine lees, they have moderate viscosity and do not require additional adhesives, which saves materials and time.
