At present, with the government's encouragement and the various advantages of organic fertilizer to the planting industry, more and more manufacturers use organic fertilizer granulator and other organic fertilizer equipment for organic fertilizer production, organic fertilizer production line processing finished products with good granularity, and can achieve fully automated production has been praised by manufacturers. The traditional organic fertilizer processing process of farmers is basically completed by relying on natural fermentation power. Most farmers directly carry fermented crop straw or manure stored at home to the field. People have been used to this method of organic fertilizer, and many farmers still take it for granted. In fact, this application of organic fertilizer will pollute the living environment such as air and water, and we need to use organic fertilizer equipment such as extrusion granulator to make organic fertilizer to improve the efficiency and output of organic fertilizer.
