NPK compound fertilizer production line ammoniating granulation

Ammonization granulation of npk compound fertilizer production line: The principle is to add potassium chloride and sulfuric acid into the reaction tank to heat and react under certain conditions. After the escaped HCL gas is absorbed by water, a certain concentration of hydrochloric acid can be produced to produce potassium hydrogen sulfate Mixed with dilute phosphoric acid to form mixed acid. The mixed acid and synthetic ammonia are reacted in a tube reactor in proportion to produce a compound fertilizer slurry that is directly sprayed into a drum granulator to produce a sulfur-based compound fertilizer with a certain proportion of nitrogen, phosphorus, and potassium. It has the characteristics of uniform granulation, bright color, stable quality, sufficient nutrients, easy to dissolve and being absorbed by crops, etc. Especially, it is relatively safe for seeds as a seed fertilizer. It is suitable for all kinds of soil, wheat, corn, fruits, peanuts, vegetables, beans, flowers, fruit trees and other crops and economic crops. It is suitable for basal fertilizer, seed fertilizer, top dressing, seed fertilizer and flushing application.
Npk compound fertilizer production line amino acid process process: A variety of basic fertilizers and additives are measured in batches according to the requirements of the process formula, and they are uniformly stirred by the mixer and returned together with the returned materials, and then conveyed into the granulator by the electronic metering belt. Sulfuric acid with a concentration of 98% or 93% is purchased from a tank truck and stored in a sulfuric acid storage tank, and then pumped into the sulfuric acid dilution storage tank and measured for granulation. The liquid ammonia is evaporated into gas ammonia and transported into the granulator through the pipeline. Ammonia and sulfuric acid continuously react in the pipeline in the granulator and directly enter the granulator material layer for granulation. The materials are agglomerated into granules in the granulator under the temperature of 70~80? and the regulation of steam. The granulated wet material is cooled and hardened on the belt conveyor, and then enters the dryer for drying and dewatering
