Coal processing is necessary in coal usage and supplying right size coal ores for coal industry. Coal processing is also the important coal mining equipment which process coal with crushing, grinding, conveying and screening, etc. Coal processing plants include coal grinding mill, coal crushing plant, coal screening plant and coal belt conveyor, etc and Hongxing Machinery supplies all kinds of those coal processing plants.
Coal mill is the most important coal processing plant as coal is usually fed into fire power plant to generate energy. Hongxing Machinery vertical coal mill is the one we designed for coal pulverizing and is featured with high capacity, high efficiency and long service time. Ball mill, hammer mill and other coal grinding equipments are also widely used in cola processing.
Coal crusher is widely used in the coal crushing process. As technology developed, now we have many types of coal crushers, including jaw crusher, cone crusher, impact crusher and portable crushing and screening plant. Hongxing Machinery supply a whole set of coal crushing production line to coal processing industry.
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. Hongxing Machinery vibrating screen is welcomed during coal crushing and coal grinding process.
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.china magnetic separator:http://www.hx-crusher.com/magnetic_separator.html

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.
Since the year 1980 When Hongxing Machinery was launched, we kept developing and researching new coal processing technology and plants. With the dream of “century enterprise”, Hongxing Machinery always urge us to produce more and better coal processing equipments. Now Hongxing Machinery 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.
