(297). Start a Coal Beneficiation Business


coal production lineCoal is a combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, with smaller quantities of sulfur, oxygen and nitrogen. Coal mining is to remove coal from the ground. Coal is valued for its energy content, and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Coal in energy production and consumption of fossil important. Main types of coal bituminous coal, anthracite, lignite, semi-bituminous coal. Different types of coal, its composition and quality of different heat is not the same. Coal moisture content of 10% -20% General, fineness of pulverized coal for industrial use is mainly present between fineness 100 mesh-250 mesh.


Coal mining is to remove coal from the ground. Coal is valued for its energy content.Coal mining consists of the removing or extraction of the earth coal which is utilized as fuel. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. Coal mines are in conjunction also known as collieries. There are diverse methods of coal extraction and sophisticated coal mining equipment is utilized in the process. Usually by mechanical or chemical treatment process to remove harmful impurities in coal, the recovery of associated minerals, to improve coal quality, adapted to different users of coal to provide quality products and products associated minerals. Harmful impurities in thecoal ash, sulfur, water, a small amount of phosphorus and other minerals under. In addition,in some rare metals such as coal contains a small amount of germanium, uranium, vanadium and associated radioactive minerals.

Coal Beneficiation Technology
Preparation methods for different levels of coal of different particle size sorting. Harmful impurities in coal and must meet the monomer dissociation can be effectively sorting. Therefore, the process of coal washing before entering must pass through the coal preparation phase, to be broken will be different to different particle size of coal.
Coal Preparation Plant in general are included in the screening stage, picking and crushing several operations, including hand-selected manual labor jobs are the most onerous Preparation Plant, a job, it should be the effective use of modern means of Coal Preparation Technology to be eliminated.
Coal Beneficiation Development Process
1. Selective fragmentation in the coal and waste rock block a significant difference in hardness, the use of coal crushing machine will be broken off election, to rule out a qualified waste rock, or a fraction of hard coal has not broken out, only fraction of workload to be hand-selected fish out coal, discarded waste rock blocks and debris;
2. HM cleaning methods used exclude large waste rock, very effective on the open-pit mining;
3. All broken into the washing machine discharge refuse after the job, such as using jaw crusher with large pieces of broken waste rock and coal into the washing operation.
In short, according to the coal and harmful impurities from the monomer solution size, large pieces of content, use of mechanical models of Coal Preparation methods and other factors, control of the coal at the preparation stage to a certain size limit, or divided into different grain degree level, preparing for the washing.
Our company’s various coal crushers and coal mills and other equipment can be used to choose mine, for example: coal jaw crusher, coal mobile crusher, coal mill, vibrating feeder, virbrating screen, belt conveyor.


Coal beneficiation is definitely the preferred option over blending. Due to the wide heterogeneity of Indian non coking coals, there cannot be a single scheme for beneficiation of thermal coals having varying washability / heterogeneity characteristics. There are many technological options for thermal coal beneficiation depending on the quality requirement of the end users. The entire chain from raw material to value added product involves different activities and improvement of the overall efficiency of the process is critically dependent on the improved performance of the individual sub-processes.

Coal beneficiation is the process of removal of the contaminants and the lower grade coal to achieve a product quality which is suitable to the application of the end user - either as an energy source or as a chemical agent or feedstock. A common term for this process is coal "washing" or "cleaning".

Coal processing is a broader term used to describe the complete process of sizing, handling and washing of the run-of-mine coal.

  • With depletion in availability of good quality power coal and large scale,mechanized opencast mining, the ash content in raw coal supplies to power sector has increased over the years. The thermal power industry in the country has tackled to some extent the problem of high ash inputs by designing boilers that can burn such coals, but high cost of transportation and requirement of large area for dumping of ash could not be avoided. Beneficiation of coal helps in not only improving performance of power plants but reduces transportation cost besides bringing down the adverse effects on the environment.

    Coal beneficiation equipment

    Coal beneficiation equipment could be divided into coal crusher and coal mill.Coal crusher is the main coal beneficiation equipment in coal crushing plant. Stationary coal crusher plant use jaw crusher as coal primary crushing machine, impact crusher or cone crusher as secondary crusher. Mobile crusher is a new type coal crusher,it including crushers, belt conveyor, vibraitng feeder and vibrating screen,just like a mobile coal crushing plant. Coal washing machine is a cleaning equipment which used to remove dust ,clay and other unwanted materials.Coal mill is the grinding machine used to grind crushed coal into powder.We provid ball mill and LM Vertical roller mill as coal grinding Machine.They are widely used in coal powder production line like thermal power plant.


    Coal Beneficiation Plant
    Coal beneficiation plant could be divided into two parts:coal crushing beneficiation and coal grinding beneficiation. If the coal block is bigger than the max input size of our grinding machines, it need be crushed by our stone crusher before grinding. The coal crushing plant common includes vibrating feeder as feeding material to jaw crusher, which is as primary jaw crusher. Cone crusher or impact crusher always be used as secondary crusher. After primary crushing, the coal can be feeding to Ball mill to fine grinding. To increase Ball mill effective, the vertical coal mill or coarse powder mill can be setted before Ball mill as pre- grinding.

    Process of   Coal Beneficiation 
    Coal is highly variable with respect to the physical and chemical properties that affect its use. Industries that use coal specify a range of properties that are required for their intended process. Coal suppliers try to find coals that most closely match those requirements. Coal is treated in processes called "beneficiation" to prepare a material that meets the customer's needs and is as homogenous as possible. Samples of coal from both cores and mines are taken to determine the treatment that must be performed. Preparation plants that perform specific beneficiation processes are constructed as near as possible to the location where the coal is mined.
    Three kinds of processes may be performed at the plants: 
    (1) sizing, controlled by a crushing and screening process, 
    (2) increasing heating value, by removing noncombustible ash and rock by gravity separation, 
    (3) removing or controlling undesirable mineral and chemical components (sulfur, sodium, and trace elements) by a combination of gravity separation and blending. Traditionally, most coal preparation was primarily concerned with sulfur and ash reduction. Today, however, much more sophisticated processes have more narrow and complex physical and chemical requirements for coal stock.
