determination of moisture content in a running coal belt conveyor
Moisture determination in coal using microwave
1991-11-1 The principle of microwave absorption due to the presence of water has been applied to the online determination of moisture in coal on a running conveyor belt. An empirical relationship between the percentage water in the coal and the resultant microwave signal was determined experimentally. Applicable software running on a personal computer coupled via suitable interfacing to the microwave ...

Determination of moisture in coal, in the case of ...
2002-2-20 Determining the moisture content in coal using this method , is based on the increase of its dielectric constant as a result of the increase in the moisture content. The dielectric constant k 1 of water is 80 whereas for most substances this has a value lower than 10. In particular, for materials with a high proportion of carbon, such as coal, values range between 3 and 5.

Microwave-based Moisture Measurement of Bauxite Ore
2020-4-8 Figure 6 shows a trend graph of the moisture content of the bauxite ore over a period of 20 minutes. Such variations are virtually impossible to detect from stop-belt sampling of ore, but are easily detected by an on-line analyzer. Trend graphs, like in

Methods for determination of moisture content in
2004-5-1 Today, moisture content is determined by standard oven method, SS 18 71 70 [1]. The method lasts from 4 h up to 16 h. To speed up the drying part, samples are heated in a microwave oven at some places. The bio-fuel is often heterogeneous and varies in MC from the extreme points 10–65%, but mostly between 45 and 55%.

Determination of the ash content of coal using ...
The ash content of coal can be determined by a simple technique based on the simultaneous measurement of 0.511 MeV annihilation radiation and Compton scattered radiation which result from irradiation of a coal sample with γ-rays of energy > 1.022 MeV. The technique has been tested by many laboratory measurements on 57 bulk coal samples, each weighing 100-200 kg, from three different

With this sampling rate, crucial information on the moisture content will be lost.
