Graded coals are those from which the screen aperture at the washery lies between 3/16 and 2½ inches round hole. They include 'doubles', 'nuts', 'singles', 'beans', and 'grains'. Small coal has no lower limit in size but has a maximum upper limit of 2 inches. Slurry and anthracite have been defined previously in 5.1.2.

This new screening machine provides maximum screening efficiency of 87.36%, 80.52%, and 66.42% for screening coal feed of 6 + 4 mm, −4 + 2 mm, and −2 + 0.5 mm size fractions, respectively. Highly efficient screening and higher removal of ash from coal were obtained due to the design and operational flexibilities of the screening machine.
Wet screening is one of the methods used to remove fine material from the coal feed to gasification. Synfuels in South Africa undertook an investigation to quantify fine coal generation in the coal supply to gasification. Coal samples were wet screened in the laboratory and results compared to the normal dry screening procedure.
In this paper, coal screening in vibrating screen was carried out with the size ranges of −6 mm + 4 mm, −4 mm + 2 mm, and −2 mm + 0.5 mm. The vibrating screen was newly designed with ...
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are …

The coal was immersed in 1 l of distilled water and then poured over the screens. A further 2 l of distilled water was also passed through to aid the screening of the coal. The different screen fractions of coal were dried and weighed to determine the new PSD after wet screening as noted in Table A1. The slurry containing the −0.5 mm fraction ...
Quality of coke mainly depends upon the coal used in blend. As the reserve of good coking coal is diminishing, at this point of time, it is important to give emphasis on coal-preparation techniques. Keeping this in mind, this article presents a coal-preparation technique named "differential screening" based on a selective crushing principle.

Screening of coal is one of the processes carried out to produce clean coal suitable for the blast furnace. In this work, the screening of moist coal was carried out for different angles of the screen and frequencies. A 2 mm screen perforation was used to separate undersize coal of size +1 mm-2 mm from the +1 mm-3 mm coal samples.
