In this study, a short view was given on dry cleaning methods. Dry cleaning provides a number of advantages for coal The dust removal efficiency of dry dust collectors is low, especially with the decrease of coal dust particle size. To improve the collection and removal efficiency Experimental investigation on highly efficient collection and

Conventional and recent advances in gravity separation
In this study, the works about gravity separation for coal cleaning in the last 10 years were reviewed. It was found that the studies have mainly contributed to the separation of fine coal as well as dry-coal separation, while conventional technologies are more focused on modeling to estimate and control the separation process.(e) Coal preparation and processing plant means any facility (excluding underground mining operations) which prepares coal by one or more of the following processes: breaking, crushing, screening, wet or dry cleaning, and thermal drying.

Coal cleaning also smooths out the variation in level of impurities so that equipment for sub sequently dealing with these impurities does not have to be oversized to accom modate large peaks.

The ratio between combustible organic matter and inorganic impurities of coal is also one of the variables in coal classification. Coal gangue is a significant residue of coal mining and cleaning, which accounts for approximately 10–15% of raw coal [3].The first group of impurities in coal, which are also the most commonly encountered, are The wet beneficiation process for coal cleaning is currently the predominant method of purification of coal in the world. However, dry beneficiation of coal has obvious advantages over wet processes. The dry processes for coal are based on the physical properties of coal and its associated mineral matters.

Dry processing for coal preparation: a review
Dry coal processing benefits downstream utilizations through possible cost and energy savings along with a reduction in water pollution. As a result, dry processing has inspired interest in the coal preparation industry and research into many methods has commenced. Addendum A: Performance report on the applicable dry coal processingWet cleaning. Wet cleaning refers to methods of professional cleaning that, in contrast to traditional dry cleaning, avoids the use of chemical solvents, the most common of which is tetrachloroethylene (commonly called perchloroethylene or "perc").

The 200-mesh sieve is equivalent to 74 microns and usually is the smallest used in the industry. Generally coal particles minus 48-mesh (295 microns) are considered dust. A few plants dedust at 28 mesh and a few at 10 and 14 mesh. Coal dust is formed by cutting, drilling, blasting, grinding, and abrasion in the mine and preparation plant.The wet beneficiation process for coal cleaning is currently the predominant method of purification of coal in the world.
