The livestock and poultry breeding industry has developed rapidly, with the characteristics of regionalization, scale, and intensive management. Animal husbandry has made significant contributions to the improvement of people’s living standards, but it has also caused serious environmental pollution, hindering the sustainable and stable development of the animal husbandry industry. Animal manure is rich in organic matter and a certain amount of nutrients such as nitrogen, phosphorus, and potassium, making it a good source of organic fertilizer. If livestock manure is not treated and directly discharged into the environment, it not only pollutes the environment, spreads diseases, but also causes waste of resources. Therefore, it is very important to use organic fertilizer production lines for harmless and resourceful treatment of livestock and poultry manure.
The organic fertilizer production line utilizes modern microbial technology, mainly livestock and poultry manure, with bran, peanut shell powder, crop straw, and other auxiliary materials and bacterial strains fully mixed. It uses equipment such as dehydrators, fermentation stackers, semi wet material crushers, horizontal mixers, organic fertilizer granulators, dryers, coolers, drum screening machines, film wrapping machines, packaging equipment, and belt conveyors to quickly heat up, ferment, and decompose Bioorganic fertilizer produced after a series of harmless treatments such as deodorization.
The organic fertilizer crusher adopts a two-stage rotor for upper and lower crushing, without the design of a screen bottom, a high alloy wear-resistant hammer head, and bidirectional gap adjustment technology. If the hammer blade is worn, it does not need to be repaired, but can be moved to continue using. Adjusting the gap between the hammer head and the lining plate can control the particle size of the material. Only one person is needed for easy operation and easy maintenance. The material passes through the upper rotor crusher to form small particles, and then is transported to the lower rotor to continue crushing into fine powder, achieving the good effect of material powder and hammer powder. After that, it is directly discharged from the discharge port. When crushing wet materials, there will be no blockage of the material outlet, and rainy weather will not delay the normal production and use of customers.
Roll extrusion granulator: No drying process to achieve room temperature granulation, one-time molding, with the advantages of low investment, fast efficiency, low energy consumption, long service life, and high granulation rate. This machine has no discharge of three wastes, stable and convenient operation, advanced and reasonable technology, compact and novel structure, and is matched with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production. It is a promotion project of national environmental protection applicable technologies.
