Generally speaking, the key equipment for bio-organic fertilizer production is the processing equipment before fermentation, mainly crushing and stirring equipment; the second is the turning equipment used during fermentation; the third is the deep processing equipment after fermentation, mainly the organic fertilizer granulator.

The quality of raw material processing in the early stage will directly affect subsequent production. There are various types of crushers for different materials to be crushed. For example, materials that tend to clump, long fibers, wood, etc., require different shredders. The mixing equipment can be selected according to the output. There are single continuous discharging and double interval discharging. The appropriate one can be selected according to the needs to improve production efficiency.

The fermentation process generally uses a trough-type stacker. The materials can be stacked in the trough to a higher height, which can save space and efficiently turn the stack. Of course, relatively flexible strip-stack fermentation can also be considered. This method has no special requirements on the site, But it occupies much larger area than tank fermentation.

In the deep processing stage after fermentation, that is, the fertilizer granulation process, the most important thing is the granulator machine for fertilizer. It depends on what kind of product is produced and what materials are added in it. There are dedicated organic fertilizer granulators and compound fertilizer granulators. These all correspond to materials suitable for production. Therefore, more investigations and comparisons are required when choosing bio-organic fertilizer production equipment.
