Problems solved by technology

However, the content of biuret in the high-tower urea-based compound fertilizer produced by high-tower granulation in the prior art exceeds the standard, and this problem has been plagued by most enterprises in this industry
This is because the excess of biuret in the compound fertilizer will lead to the burning of large areas of crop seedlings, which happens from time to time all over the country, causing huge economic losses to farmers
Although the country has repeatedly discussed the issue of biuret content standards in compound fertilizers, and high-tower compound fertilizer companies have tried their best to find ways to reduce the biuret content in their products, but the problem has not been resolved from the root cause

Abstract

The invention discloses high-tower granulated urinary-chlorine-based compound fertilizer and a preparation method thereof. The high-tower granulated urinary-chlorine-based compound fertilizer is prepared from raw materials in parts by weight as follows: urea, a fluxing agent, an anti-caking agent, potassium chloride, potassium sulfate, monoammonium phosphate, ammonium chloride, ammonium sulfate, zinc stearate, zeolite powder, calcium carbonate powder and dolomite powder, wherein the anti-caking agent is prepared from raw materials as follows: plant oil, cyclohexanone leftovers, low-fat carbon alcohol, natural ore powder and a modifier. The urea is melt at the top of a high tower, a urea solution is prepared and conveyed to the top of the tower, time for decomposing the urea solution and producing biuret is greatly prolonged, meanwhile, the urea melting temperature is reduced by means of the fluxing agent, the urea is melt at low temperature, generation of biuret which is harmful to crops is greatly reduced, and besides, conditions are provided for reduction of the temperature for pulp mixing; the prepared urinary-chlorine-based compound fertilizer has a good anti-caking effect.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a high-tower granulated urine chlorine-based compound fertilizer and a preparation method thereof. Background technique [0002] Since 2000, my country's fertilizer industry has developed rapidly. As a wonderful work in the compound fertilizer industry, the high-tower granulation process has rapidly taken root and blossomed all over the country. According to incomplete statistics, the current national high-tower compound fertilizer production capacity has reached 5 million tons. , The actual output in 2008 was about 3 million tons. However, the content of biuret in the high-tower urea-based compound fertilizer produced by high-tower granulation in the prior art exceeds the standard, and this problem has been perplexing most enterprises in this industry. This is because the excess of biuret in the compound fertilizer will cause a large area of ​​crop seedlings to be...
