The process of
granular organic fertilizer production equipment is complicated. The previous article explained how to pretreat organic fertilizer raw materials. Today we will introduce what other processes the pretreated organic fertilizer raw materials need to go through to become granular organic fertilizer.
1. Granulation stage
Purpose: to make the dried organic fertilizer into granules for easy storage, transportation and use.
Main equipment:
Granulator: such as disc granulator, extrusion granulator, rounding machine, etc. These devices make the material into granules through different mechanical actions.
Granulation process:
The dried material is fed into the granulator and formed into granules through processes such as rotation and extrusion.
The size and shape of the particles can be controlled by adjusting the parameters of the granulator.
2. Cooling and screening stage
Purpose: to reduce the temperature of the particles, remove unqualified particles, and improve the quality of the finished product.
Main equipment:
Cooler: such as rotary cooler, which uses air flow to speed up the cooling of the material.
Screening machine: such as drum screening machine, which classifies particles according to size and removes unqualified particles.
3. Packaging stage
Purpose: to pack qualified granular organic fertilizer into packaging bags for easy storage and transportation.
Main equipment:
Packaging machine: such as electronic quantitative packaging scale, automatic sewing machine, etc., which can realize automatic weighing, packaging and sealing.
Packaging process:
Qualified granular organic fertilizer is sent to the packaging machine, and the packaging process is completed after automatic weighing, packaging and sealing.
In summary, the process of
granular organic fertilizer production equipment includes pretreatment, fermentation, drying, granulation, cooling and screening, and packaging. Each stage involves specific equipment and operation processes, which work together to complete the production of organic fertilizer.
