Filler-free synergistic compound fertilizer produced by urine syrup ammonia-acid method and production method thereof

Abstract

The invention discloses a filler-free synergistic compound fertilizer produced by a urine syrup ammonia-acid method to pelletize and a production method thereof. The production method thereof comprises the following steps: selecting raw materials according to the product formulation, and metering, crushing and evenly mixing the raw materials; adopting the urine syrup ammonia-acid revolving drum pelleting process, carrying out first-segment drying, second-segment cooling and coarse and fine screening on the mixture, and then feeding the screened mixture into a coating machine; utilizing the front end of the coating machine to spray fertilizer synergist by a continuous pulverization coating method, utilizing the middle end of the coating machine to spray pasty anti-blocking agent, and utilizing the tail end of the coating machine to add powdery anti-blocking agent; and adequately stirring and packaging to obtain the finished product. The filler-free synergistic compound fertilizer produced by the pelleting process of the urine syrup ammonia-acid method has small investment, simple operation, low production cost, obvious energy conservation effect, beautiful product appearance, good dissolubility and improved nutrient utilization ratio; and after the filler-free synergistic compound fertilizer is applied to crops, production and income are increased.

Description

technical field

[0001] The invention relates to the technical field of fertilizers, in particular to a synergistic compound fertilizer without fillers produced by the urine plasma amino acid method. Background technique

[0002] Fertilizer is the food of plants, an extremely important means of agricultural production, and an important guarantee for the development of agricultural production and national food security. With the continuous development of my country's chemical fertilizer industry and agricultural production, compound fertilizer, as a fertilizer with relatively complete nutrients, has developed rapidly in recent decades.

[0003] At present, the production of domestic compound fertilizers has problems such as high energy consumption, high pollution, and large investment. Compound fertilizer companies are facing fierce market competition. It is very important for products to have competitive advantages. Compound fertilizers containing fillers are affected by fill...
