Compound fertilizer contains nutrients required for crops
Compound fertilizer refers to chemical fertilizers containing two or more nutrients. The compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate and promoting high yield and stable yield of crops. The role. The drum granulator is one of the key equipment for the production of compound fertilizer. Such fertilizers can save packaging and transportation costs, reduce the number of fertilizations, and design and distribute fertilizers according to the local soil nutrient supply status and target crop fertilizer characteristics. Make an outstanding contribution to the green development of crops.
Compound fertilizer characteristics
The production of compound fertilizer in drum granulator uses soil testing formula to measure the nutrient of soil. According to crop fertilizer requirement, soil fertility performance and fertilizer effect, based on rational application of organic fertilizer, nitrogen, phosphorus and potassium are proposed. The amount of fertilizer applied to the medium and trace elements, the fertilization period and the application method. The drum granulator can add what elements are needed according to what is missing in the crop, how much to make up, to achieve a balanced supply of various nutrients, to meet the needs of crops; to improve fertilizer utilization and reduce dosage, increase crop yield, and improve the quality of agricultural products, Save labor, save money and increase income.
Compound fertilizer production process—-drum granulator
Drum granulation is also called drum granulation. Drum granulator is the most widely used equipment in the type of compound fertilizer production equipment. The recipe limits are relatively small. It is also possible to use part of the shotcrete and partially ammoniat. 2-3 million can be used as a production line, the daily output can reach 280-400 tons, and the good formula can reach more than 500 tons. The drum granulation production process is favored by many compound fertilizer manufacturers because of its relatively limited formulation, high output, low investment, and short construction period. It is used by more and more compound fertilizer manufacturers.
