DEF

Coal screened between specified size limits.

DEF

One of the three main size groups by which coal is sold by the National Coal Board in Great Britain. It consists of coal screened between two screens - with an upper and lower limit varying from a top size of 2 or 1 1/2 inches to a bottom size of 3/4 to 1/8 inch.

CONT

From the QCCF coal receiving pit, the raw coal is sent to the screening machine to be screened to ensure the grain sizes for the whole machine are within the required range of 6-50 mm. The machine that performs this process is the air-heavy medium separating machine. The air-heavy medium forms a fluid bed with stable density, separating the screened coal into cleaned coal and tailings. The ash content of the cleaned coal produced in this process is generally below 15%.
