China’s livestock and poultry breeding industry has developed with remarkable speed. Poultry (chicken) and swine farming have become commonplace and represent large-scale enterprises within the sector. Large and medium-sized intensive breeding farms have been established in many suburban areas, leading to a rapid increase in livestock numbers. This has enriched the supply of animal products and by-products for urban and rural residents, thereby improving living standards.
However, the production of livestock and poultry manure is also increasing rapidly. This manure contains significant amounts of nitrogen, phosphorus, suspended solids, pathogenic bacteria, and high concentrations of organic pollutants. If not treated properly, it poses severe hazards to the atmosphere, water bodies, soil, and living organisms. Environmental pollution caused by chicken manure is a key issue that must be resolved. Since livestock and poultry manure is rich in nutrients, applying it to land can improve soil compaction, enhance fertility, and benefit crop growth. However, applying raw manure directly to the land poses significant risks to both soil and crops. Currently, utilizing organic fertilizer production line equipment to process this waste into organic fertilizer allows for the production of guaranteed, high-quality organic fertilizer. Given that the treatment of livestock manure is a long-term, continuous necessity, and the use of organic fertilizers represents a development trend in agriculture, this processing method is essential.
The organic fertilizer production line equipment used to produce granular organic fertilizer from chicken manure includes a series of supporting machines: organic fertilizer turners (windrow turners), organic fertilizer crushers, forklift hoppers, automatic batching machines, organic fertilizer mixers, powder screening machines, organic fertilizer disc granulators, organic fertilizer dryers, cooling machines, granule screening machines, rounding machines, coating machines, and packaging machines. The selection and configuration of organic fertilizer production line equipment are planned based on the customer’s specific raw materials and the volume of manure and materials to be processed.
The Structure and Advantages of the Organic Fertilizer Disc Granulator
The pan angle of the organic fertilizer disc granulator adopts an integrated arc structure, ensuring a high granulation rate. The granulation pan is equipped with three discharge outlets, which facilitates intermittent production operations, greatly reducing labor intensity and improving work efficiency. The reducer and motor utilize a flexible belt drive, ensuring smooth startup, buffering impact forces, and extending the service life of the equipment. The bottom of the granulation pan is reinforced with multiple radial steel plates, making it solid and durable. The base design is weighted, thickened, and robust; it operates smoothly without the need for anchor bolt fixation. The main gear of the granulator undergoes high-frequency quenching, which doubles its service life. The liner inside the granulation pan is made of high-strength fiberglass, offering corrosion resistance and durability. This machine boasts advantages such as uniform granulation, high granulation rates, stable operation, robustness, and a long service life, making it an ideal choice for a wide range of users.
To protect and optimize the natural ecological environment, and to control and eliminate pollution caused by livestock and poultry manure, one crucial approach is the harmless treatment and resource utilization of such waste. This prevents pollution from breeding farms and safeguards the natural ecosystem, thereby promoting sustainable agricultural development. Regarding the vast quantities of manure produced, even when breeding farms previously had related treatment measures, the processing level mostly remained at the primitive stage of stockpiling fermentation for field application. This outdated method of compost manufacturing has significant drawbacks, including large volume requirements for stockpiling, strong odors, and unsanitary conditions.
