Comparative analysis of stable fertilizer production processes
26-10-12 stable fertilizers are produced by drum granulation process and high tower melt granulation process,production indicators,product indicators and raw material costs are compared to explore the suitable production process for high nitrogen stable fertilizers.The results show that,compared with the drum granulation process,the high tower melt granulation process has a 67.8%increase in hourly production,a 44.4%increase in product particle strength,a 33.3%increase in finished product yield,a 6.4%increase in finished product nutrient qualification rate,a 11.6%reduction in raw material production cost,a 107.78%increase in residual urea rate,and a 128.11%increase in nitrification inhibition rate.Therefore,the high tower melt granulation process is more suitable for producing 26-10-12 high nitrogen stable fertilizer products than the drum granulation process.
