Methods for reducing the returned materials quantity of high tower compound fertilizer during formula changing period
Due to the influence of the market,the formula changing of high tower compound fertilizer is more frequent.According to the conventional formula changing method,a large amount of returned materials will be generated during the formula changing period,which reduces the profit of the enterprise.Taking the production of compound fertilizer 26-10-26 as an example,the formula changing method is introduced,which involves continuing to add potassium chloride and monoammonium phosphate powder to the mixing tank during the emptying of the urea melting tank,and continuing to add monoammonium phosphate powder to the 2# mixing tank during the emptying of the 1# mixing tank.This can ensure that the nutrients of the slurry are qualified,and there is no need to return materials during the formula changing period.The specific calculation method and process control of the feeding amount are introduced.By using this method,it is possible to achieve no material return during the formula changing period,resulting in good economic benefits.
