Coal Preparation Plant Working Principle2019-11-01


After the extracted from mines, coal varies widely in size, ash content, moisture content, and sulfur content. Coal preparation processes aims to improve the ROM coal to for final application demands, as per the requirements of each industrial application. One important purpose of coal preparation is to increase the heating value of the coal by mechanical removal of impurities and gangues. Different types of mechanical cleaning equipment and coal preparation plants are required for cleaning of coals in different size ranges. Coal larger than eight inches is usually crushed to a smaller size; when lump coal is required, the large fraction is cleaned by slate pickers.

coal processing equipment

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 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. SBM company supply a whole set of coal crushing production line to coal processing industry. Coal mill is the most important coal processing plant as coal is usually fed into fire power plant to generate energy. SBM company 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 separation method

Air jig for separation of minerals process is aimed to make even particles size by crushing, grinding, and wet or dry classification. air jig for separation of minerals process involves several different stages and may use dry or wet ore feed. Generally, primary crushing and screening happen with the mine site. Primary crushing ends through the use of jaw crusher, air jig for separation of minerals and cone crushers. Primary crushing produces particles ranging bigger from Five to ten inches. Oversize material is passed through additional crushers and classifiers to achieve the desired particle size. The information is then crushed and sized at a secondary air jig for separation of minerals from coal.
