摘　　要：目的通过有效改进粉体物料容重检测方法,以提高水泥的检测结果的正确性与检测效率。方法通过导管处辅助金属小棒旋转的技术改进,以松动物料使其自然下落,对水泥容积密度检测技术改进前后的检测数据作对比,找出更环保、更快速、准确的试验方法。结果改进后的检测数据不因设备位移而发生波动,松散状态下的水泥容积密度保持在1.03 g/cm^(3),整个试验过程用时较短(1.5 min),且试验过程无扬尘,试验结果没有超出误差范围,均优于未改进前的测定数据。结论改进后的检测方法更加科学地提高水泥性能检测的准确性和精度,可使检测结果更加接近真实值,可行性较强,具有一定的社会经济价值,值得推广。Objective To improve the detection method of bulk density of powder materials,in order to improve the accuracy and efficiency of the detection results of cement.Methods Through the improvement of auxiliary metal rod rotation technology at the pipe to loosen the material and make it fall naturally,the detection data before and after the improvement of cement volume density detection technology were compared to find a more environmentally friendly,faster and accurate test method.Results The improved test data did not fluctuate due to the equipment displacement,and the cement bulk density remained at 1.03 g/cm3 in the loose state,the whole test process took a short time(1.5 min),there was no dust in the test process,and the test results did not exceed the error range,all of which were better than the measured data before the improvement.Conclusion The improved test method can improve the accuracy and precision of cement performance test more scientifically,and can make the test results closer to the real value,which is feasible,has certain social and economic value,and is worth popularizing.
