The objective is to get water on the fine coal, most of which lies at the bottom of the coal, next to the belt. This means the large coal particles on the top receive a large portion of water. When water is sprayed directly on coal as it moves along a belt, water must ''filter'' down through the coal to wet the fine coal.
Benefits of Coal Moisture Analysis. Using the CCS3000, you''ll be able to cut production costs while boosting product quality. The CCS3000 is low maintenance and energy efficient.

Then total moisture (TM) is a sum of IM and SM. Total moisture in coal is used to determine the amount of drying that is needed to reach a given moisture requirement and to determine the amount of dustproofing and freeze-proofing agents to add. In coking processes, coals with a high moisture …
The determination of total moisture is carried out on an as-sampled coke sample which has been protected from contamination. The pre-weighed coke is dried, without crushing, to a constant weight at more » 104 to 200/sup 0/C, and total moisture is calculated from the weight loss.

The mined coal was crushed, to a top size of 50 mm, by means of a two roll crusher fitted with a 50 mm grizzly screen in the feeder end. The test plan was conducted in two ways – A) SMALL SCALE (50 KG): The small scale test program provided an additional means to measure the maximum moisture loss of stacked coal over a period of time.
moisture sample, all operations shall be done rapidly and in as few operations as possible, since moisture loss depends on several factors other than total moisture content, such as time required for crushing, atmospheric temperature and humidity, and type of crushing equipment. 7.2 While awaiting preparation, the uncrushed gross mois-

· Coking coal is a naturally occurring sedimentary rock found within the Earth''s crust. Categories of coking coal include hard coking coal, semi-hard coking-coal or semi-soft coking coal, and coal for pulverized coal for injection (PCI). These apply to the different quality grades of the coking coal, all of which are used in ironmaking.
Two Stage Total Moisture Formula (Refer to ASTM D3302 section 10) Two stage total moisture determination is used when the coal sample is too small mass or too wet to divide or crush without the potential of losing significant amounts of moisture. TMar, …
The content of sulfur, silicon, aluminum, iron in coal is determined rapidly by spectrum method, and the ash and calorific value are given by fitting. Meanwhile, the total moisture content is analyzed by moisture analysis unit (based on thermogravimetric method). It only take 2 minutes from acquiring analysis sample to attaining analysis results.

· The 28 mesh by 0 coal, sometimes a combination of hydroclone clean coal (28 by 100m) and flotation froth (100m by 0), is dewatered by vacuum filters to a 22 to 23 pct surface moisture content. Because of the increased surface area with decreased particle size, the fines will absorb and retain considerably more moisture than the coarser fractions.
