DMCs are commonly used to treat particles of coal and rock that are too small (usually 0.5 to 12.5 mm) to float or sink in a static vessel. These high-capacity devices make use of the same basic principle as dense medium vessels (i.e., an artificial magnetite-water medium is used to separate low-density coal from high-density rock).

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
Answer & Explanation Answer: D) Rotating table feeder Explanation: The coal is supplied through the rotating table feeder at the upper right to fall on the inner side of the races. The moving balls and races trap coal between them to crush it to powder. Spring holds down the upper stationary race and adjusts the force needed for crushing.
Williams Reversible Impactors are among the most advanced of the secondary or tertiary crushers to achieve a high reduction ratio. Reversible Impactors are used effectively as stone crushers, and are also well suited for reducing a variety of other materials such as coal, ore, clay, shale, refractories, ceramics, scrap glass, chemicals, fertilizers, and more to a uniform cubical shape.
a reduction ratio of around 10:1 to 25:1 and are hence used for the extracted materials, sand, gravels etc. [6]. Vertical shaft impact crusher These crushers use a high speed rotor that has its axis along the vertical axis. The vertical-shaft impact crusher can be considered a stone …
