Pig manure, as a high-quality organic fertilizer raw material, can be transformed into valuable waste through appropriate organic fertilizer equipment treatment and conversion, and made into efficient organic fertilizer. The following is an introduction to the main production process and equipment used for pig manure organic fertilizer:

Overview of Process Flow
Raw material collection and pretreatment
Pig manure is first collected to remove impurities such as plastic bags, stones, and other non organic substances, and then subjected to preliminary crushing to increase the surface area of the material and promote subsequent fermentation.
Fermentation treatment
Using fermentation facilities such as fermentation tanks or fermenters, adding beneficial microbial strains to accelerate the biodegradation process of pig manure, eliminate harmful pathogens, and release nutrients to increase fertilizer value.
dry
Fermented pig manure usually contains a high amount of moisture, which needs to be reduced to a suitable level for granulation through a dryer.
smash
The dried pig manure is crushed into finer particles by an organic fertilizer grinder for subsequent granulation.
Mixing and Ingredients
Mix the crushed pig manure with other organic materials, minerals, or additives as needed to obtain the desired fertilizer formula.
Granulation
Utilize organic fertilizer granulators, such as disc granulators, drum granulators, or roller extrusion granulators, to form uniform particles of the mixture.
Cooling and drying
The newly granulated organic fertilizer needs to undergo cooling and drying steps again to ensure that the particles do not deform and to prevent bacterial growth.
screen
Finally, the organic fertilizer screening machine is used to remove unqualified large particles or powdery materials, ensuring the consistency of the product.
packing
Qualified organic fertilizer particles are measured and sealed in bags, ready for sale.
Introduction to Key Equipment
Fermentation equipment: such as fermentation turntables, used to accelerate the anaerobic or aerobic fermentation process of pig manure.
Drying machine: A drum dryer is often used to evaporate a large amount of water from pig manure.
Crusher: Used to crush fermented pig manure into small particles for easy mixing and granulation.
Granulator: such as a roller extrusion granulator, it can produce dense and hard particles that are suitable for the characteristics of pig manure.
Cooling machine: helps the newly granulated organic fertilizer to quickly cool down and prevent thermal damage.
Screening machine: Ensure that all organic fertilizers leaving the factory have consistent particle sizes to improve product quality.
The establishment of a pig manure organic fertilizer production line requires comprehensive consideration of various factors such as raw material characteristics, target yield, and market demand, and the selection of appropriate equipment combinations to achieve optimal production efficiency and product quality. In addition, emphasizing environmental protection and energy conservation is also an important consideration factor in modern organic fertilizer production.
