The products produced after the coal washing process are generally divided into gangue, medium coal, grade B clean coal, and grade A clean coal. The finished coal after the coal washing process is usually called clean coal. Through coal washing, the transportation cost of coal can be reduced, and the utilization rate of coal can be increased.
McLanahan equipment can reduce the amount of fine coal waste that is destined for the settling pond or gob pile by converting it into a dry, dripfree product that is safer and easier to handle. In some cases, these tailings can be repurposed as a saleable product. McLanahan equipment can also help coal producers struggling with an insufficient ...

China's total coal production in 2021 exceeded billion tons, 52% of the world's total. Coal gangue, a solid waste of coal mining accounts for 1520% of coal production, when directly discharged on the ground surface as waste heaps, it occupies large areas of land and cause environmental pollution. This paper summarizes the existing gangue backfilling methods, their working ...
Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

Total yield of tailings was % with calorific value around 1,311 kJ/kg, ash content % and sulfur content %. Receiving the clean coal products was not the main purpose of this test. Sulfur content is increasing in clean coal products which show that sulfur is mostly appearing in coal in organic form (Table 1).
Combination machines for very large warehouses: Sweeping, scrubbing and vacuuming in one machine. We recommend using combination machines in very large warehouses with areas of over 10,000 square metres. In such areas, machines with dust suction and a filter area of up to 10 square metres are used.
