摘要
为了弄清混匀矿SiO2化验结果与预算值之间的偏差产生的原因,进行了运输皮带上全流幅截取试样与旋斗取样试验。对比分析表明,旋斗取样机取样偏差较大。
Tests with both full feed flow intercept sampling on the conveyer belt and sampling of a rotation sampler are carries out in order to make out the difference between estimated values and analyzed results.Comparative analysis shows that the sampling deviation of the rotation sampler is relatively big.
