In our previous news, Johnson wedge wire screens are commonly used in the filtration industry. So can wedge wire screens be used in other industries? The answer is yes.
This news only describes its application in coal mining: application in coal washing and coal washing technology
coal washing
Coal washing is an indispensable process in the deep processing of coal. The coal directly mined from the mine is called raw coal. Many impurities are mixed in the mining process, and the quality of the coal is also different. Coal with a small internal ash and a large internal ash is mixed together.
Coal washing is an industrial process that removes impurities from raw coal or classifies high quality coal and inferior coal.
Products produced after coal washing are usually divided into stone, medium coal, grade B and grade A. The finished coal after coal washing is often referred to as clean coal.
By washing coal, the transportation cost of coal can be reduced and the utilization rate of coal can be improved. Clean coal is often used as a fuel source. The bituminous coal is mainly used for coking. It requires desulfurization, removal of impurities and other industrial processes to achieve coking standards.
Advantages of coal washing:
(1) Washing coal can remove 50%-80% of ash in coal and 30%-40% of total sulfur
(2) Improve coal utilization efficiency and save energy
(3) Optimize product structure and improve product competitiveness
(4) Reduce production capacity waste
