Coal analysis - Wikipedia
Abrasion is the property of the coal which describes its propensity and ability to wear away machinery and undergo autonomous grinding. While carbonaceous matter in coal is relatively soft, quartz and other mineral constituents in coal are quite abrasive. This is tested in a calibrated mill, containing four blades of known mass.

COAL HANDLING SAFETY - AMETEK Land
coal and the high temperature inside the mill lead to rapid oxidation of the coal. This results in further heat build-up and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to …
Coal handling plant in a thermal power generating station
The crushed coal is then transported to the store yard. Coal is transported to bowl mills by coal feeders. 3. Bowl Mill. The coal is pulverized in the bowl mill, where it is grounded to a powder form. The mill consists of a round metallic table on which coal particles fall. This table is rotated with the help of a motor.
