The entire work at west bokaro division Mining of coal, Crushing of coal and Processing of coal is done in three shifts. The feed received at washery # 3 has a ash % ranging between 30 to 40 %, this feed after processing leaves the plant in four forms namely Concentrate, Middling, Tailings and Reject. The concentrate from washery is sent ...

Performance study The performance of a washery is evaluated by the examination of the extent of fulfilment of different duties of the plant such as (Kumar, D., 1995): Handling the required hourly throughput capacity of the plant. Effective working hours over a shift or day. Efficiency parameter of individual processing and handling units.

JHARIA REJECTS. Tata Steel coal washery rejects are produced as byproducts from its Jamadoba and Bhelatand Coal Preparation Plants. In both the plants, coal washery rejects are mixed with middlings to produce the end product '2PR or 2Product Rejects' as a part of the process. Quality of 2PR ranges from G13 to G17 equivalent of CIL coal grade.

The three most basic processes of the coal wash plant are the preparation work before the sorting (crushing, screening, grading), the sorting operation, and the processing of the selected products. At the same time, heavy medium coal preparation includes five major processes: coal flow, medium flow, circulating water system, slime water, and ...

Use of coal at the same time raises environmental concerns. The impacts of increased coal utilisation will have increased environmental impacts from emissions of air pollutants during coal mining, coal transportation and coal combustion, contamination of the surface and ground water, forest loss due to mining, etc.

In the event, the process also results in loss of coal fines, usually 610 tonnes per day from a single washery plant (Tiwary Dhar 1994; Ghose 2001). The third and fourth kind of WW is generated from steel plants and TPPs respectively, which are responsible for steel production and electricity generation from the washed coal.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Workshop on Clean Coal Technology Power Plants are designed for a particular Coal Quality range and deviation in quality adversely affects the performance and efficiency of the Plant. The key area of concern are: Ash in coal As high as 45%. Inconsistency in Quality of Coal. Chemical Quality Physical Quality. These issues can by and large be addressed by resorting to Coal beneficiation.

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
