pulverized coal mill working principle:

Raw coal coming from feeder gets ground between the grinding rolls and bull ring segments installed on the revolving Bowl. Bowl is made to rotate at medium speed for proper pulverization of coal. Springs exert necessary pressure on rolls for grinding. Hot air through the mill besides removing coal moisture, picks up the lighter particles and takes them through the classifier and drop down the higher size particles for further grinding. Fine coal air mixture leaves the mill and enters the fuel piping system. Tramp iron pieces which are not required to grind, leave the Bowl due to centrifugal force and are removed through the reject removal system.
