Coal Processing Equipment in India

Coal processing  is necessary in coal usage and supplying right size coal ores for coal industry, the most popular coal processing equipment for Coal processing contains  crushing, grinding, conveying and screening, etc.

Since Coal processing plants include coal grinding mill, coal crushing plant, coal screening plant and coal belt conveyor and so on, and we can supply all kinds of those coal processing plants in India.

Coal crusher equipment is widely used in the coal crushing process. As technology developing, we have many types of coal crushers, such as  jaw crusher, cone crusher, impact crusher and portable crushing and screening plant, mobile crusher and so on. SBM supply a whole set of coal crushing production line to coal processing industry in India.

Coal grinding mill is the most important coal processing plant as coal is usually fed into fire power plant to generate energy. SBM vertical coal mill is the latest one we have designed for coal pulverizing and is featured with high capacity, high efficiency and long service time. Ball mill, raymond mill, hammer mill and other coal grinding equipments are also widely used in cola processing.

Coal screening plant is one kind of coal selecting and purifying equipments. Coal screening plant helps to separate the right size coal granules we need from those not passable. SBM vibrating screen is welcomed during coal crushing and coal grinding process

Coal belt conveyor acts as the transporting part and joint in coal processing production line and so it is necessary during coal processing. SBM coal belt conveyor is rubber belt conveyor and runs in the circumstance temperature range from -20℃ to +40℃. SBM coal belt conveyor can work with both outdoor and downhole operation.

Coal crushing and screening plant is the whole set of coal processing production line, equipped with coal crusher, screening plant, belt conveyor and vibrating feeder. Coal crushing and screening plant is more flexible and more widely used than stationary coal crushers.

Coal processing

Coal processing goes as follow:

Coal is first crushed by coal crushers to a size of 20 to 25 mm and is then fed to coal bunkers. Coal feeders feed this crushed coal continuously to coal mill as per requirement. Coal gets ground by grinding elements in stages. Coal particles get re-circulated around four times before achieving required fineness. Classifier allows finer particles to escape mill outlet while coarse particles are returned to mill for further grinding. Primary air is supplied by P.A. fan through air pre heaters to coal mill or in some boilers, P.A. fan pressurize hot air received from air pre heaters and then supply to mills. Hot primary air drives moisture from coal and acts as carrier to transport pulverized coal to the boiler through pipes.

Output is pulverized coal having required fineness. For complete combustion coal should have fineness of 75% through 200 mesh and 99.5% through 50 meshes. Primary air + coal mixture flowing through each coal pipes should have minimum velocity of 18 m/sec, Temp. Around 80 degrees C, and air/coal ratio of 1.8 -2. Fuel flow through pipes is balanced within range of +/-10%. Finer is the coal, better is the flow distribution.

SBM coal processing plant

Since the year 1980 When SBM was launched, we kept developing and researching new coal processing technology and plants. With the dream of “century enterprise”, SBM always urge us to produce more and better coal processing equipments. Now SBM has become one of the leading mining equipment and coal processing plant manufacturers all over the world. You will enjoy of high quality coal processing plant as well as professional services.
