for coal washery and the supernatant liquid can be recycled or safely discharged without causing surface water pollution. It would maintain the acceptable balance between environmental management and sustainable development of coal washeries in the region. Introduction Raw coal contains noncoal minerals that are re

Rajrappa Washery Rajrappa Washery was commissioned in 1987 constructed by M/S MAMC. Its installed capacity is of raw coal feed which is highest in India as coking coal Washery. It is based on Jig washing technology.
We will conduct a mass balance on the total riverwater mass. In this case, the ``concentration'''' of river water in mass/volume units is simply the density of the water, . where the term has been set to zero because we are ignoring chemical reaction. Since this is a steadystate problem, . Therefore, as long as the density is constant,, or . (b)
These coals, when heated in the absence of air, from coherent beads, free from volatiles, with strong and porous mass, called coke.

Raw coal receive from underground mines and open cast mines at the rate of 2000 to 2500 tones per day at Bhojudih Coal Washery through Rail. Raw coal is carried from BOBR hopper to Single Roll crusher by belt conveyor and crushed down to 75 mm size coal and stacked in the raw coal stock Pile.
In 1973, all Noncoking Coal Mines were nationalized and brought under Eastern Division of Coal Mines Authority Limited. In 1975 Eastern Coalfields Limited, a Subsidiary of Coal India Limited () was formed and inherited all the private sector coal mines of Raniganj Coalfields.
A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation.
Mass balance approach is a commonly used indirect method to study source contributions of pollutant loads into the receiving water bodies. This approach is useful especially when there are distinct dry and wet seasons as existent in the tropical countries like India. The mass balance .

Energy Analysis of Thermal Power Plant Raviprakash kurkiya, Sharad chaudhary Abstract — Energy analysis helps designers to find ways to improve the performance of a system in a many way. Most of the conventional energy losses optimization method are iterative in nature and require the interpretation of the designer at each iteration.
the process. In addition to beneficiation of coal slurry in washery operation, the process can be utilized for recovery of the coking coal fraction from washery middlings. The tests carried out with Lodna washery middlings have similar performance parameters as with the coal slurry . The agglomerated cleans from the middlings

CCTR Indiana Center for Coal Technology Research 6 COAL RANK Anthracite coal is a dense, hard rock with a jet black color metallic luster. It contains between 86% and 98% carbon by weight, it burns slowly, with a pale blue flame very little smoke
total mass of input = total mass of output. A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes.
Coal Washing Problems associated with Indian runofmine coal ¾Indian coal has drift origin, resulted in intimate mixing of mineral matter with coal, giving rise to the ash content ¾The coalash distribution in the coal matrix in Indian coal is so interwoven that coal is essentially required to
