采用统计方法 ,针对原料磷矿个体差异 ,解决磷矿采样的代表性。根据原料质量的波动 ,对确定的采样分析频率 ,估算其平均值与实际值的差值 ,并为严格按照配方生产 ,计算折标消耗提供可靠的计算依据
Using statistical methods, aiming at the individual differences of raw material phosphate rock and solving the representativeness of phosphate rock sampling. According to the fluctuation of raw material quality, we can estimate the difference between the average value and the actual value of the sampled sampling frequency and provide a reliable basis for calculation according to formula production and calculation of the discount rate
