China’s agricultural production generally has the problems of excessive use of chemical fertilizers and insufficient application of organic fertilizers. Today, with the development of ecological agriculture and sustainable development, it is of great significance and prospect to make full use of the existing solid waste to develop bio organic fertilizer technology. After analyzing various granulation technologies at home and abroad, the solid material granulator is designed and studied. Combined with the actual technical requirements and functional requirements of organic fertilizer granulation, determine the overall design scheme of the extrusion flat mold granulator, select the appropriate design scheme, analyze and design the structure of its functional components, determine the composition of each functional component, and ensure its functional and performance requirements.
In recent years,organic fertilizer equipment has benefited from the support and guidance of relevant national policies, and the market demand has expanded and the development speed is fast.
In the application of agricultural machinery, the proportion of organic fertilizer use has begun to increase in recent years. This situation, on the one hand, is because of the production demand of the industry, but the more important thing is the support and guidance of relevant national policies, and only national policies will focus on the development of organic fertilizers. The fertilizer industry, industrial production and related projects will increase the demand for such products, from pipeline equipment in public facilities to the national power grid and Sinopec, which are closely related to the organic fertilizer industry.
In the face of the increasingly harsh natural environment, the country has to make corresponding adjustments to the development direction of related industries. For the agricultural machinery industry, since its raw materials are mainly non-renewable resources such as land, policy orientation has begun to promote environmental protection and energy conservation. Through the collection of relevant data and the further understanding of current organic fertilizer production lines, the core parts of industrial policy have begun to be touched. Production enterprises should actively face market challenges, pay attention to high-tech investment, and further adjust products according to market demand. Looking back at the early development of the organic fertilizer industry, the relevant research data of the China Organic Fertilizer Trading network show that most enterprises developed under the guidance of industrial policy support are small and medium-sized organic fertilizer producers. From the perspective of macroeconomic development, the technological development of products always promotes each other with high-tech, and simple processing and manufacturing can not drive the progress of the entire industry. Therefore, recently, there have been some changes in the policy of the organic fertilizer industry. The direction began to become more focused.
