Coal quality testing equipment Main products: calorimeter, sulfur meter, hydrogen tester, melting properties analyzer, moisture analyzer, glial layer analyzer, bond index detector, industrial analyzers, sample mill, Water products are widely used in coal, electricity, metallurgy, building materials, geology, petroleum, chemical, rubber, environmental protection, food, feed, laboratory coking, universities and research departments drum series, a moisture (M) of coal divided into two types, one is the internal water when water (Minh), is contained by the plant into a coal; the second is external water (Mf), is attached to the process of mining, coal transportation and fissures in the surface of the water . Total Moisture is the external and internal moisture coal, regardless of the sum. In general, the degree of metamorphism of coal, the lower the inherent moisture. Lignite, long-flame coal ordinary high inherent moisture, low lean coal, anthracite inherent moisture. The presence of moisture on the use of coal is extremely unfavorable, it is not only wasting a lot of transportation resources, and when coal as fuel, the coal moisture into steam, burn calories during evaporation; In addition, the moisture on the coking coal also generates some impact. Usually the water every 2% increase, reduce heat 100kcal / kg (kcal / kg); metallurgical coal moisture every 1% increase in coking time to extend the 5-10min.
