散状物料水份测量的取样装置

Sampling Device for Measuring Moisture in Particulate or Powdered Material

本文对散状物料水份测量中的密度变化这一难题进行了研究,提出了保持密度一致的各种方法与取样装置,并以煤粉为对象进行了实验,实验结果表明螺旋式一次变换器可以最大限度地克服密度对测量结果的影响.

In this paper, the difficult problem of density change during measuring moisture in paniculate or powered material is studied. A lot of methods and devices are developed in order to eliminating the effect of density change . An experiment has been made with powder coal. It shows that the screw changer is a better device for eliminating the effect of density change.
