Coal handling plant in a thermal power generating station

There are three large steel rollers, which are spaced 120" apart. When there is no coal, these rollers do not rotate but when the coal is fed to the table it packs up between rollers and the table and this forces the rollers to rotate. Coal is crushed by the crushing actions between the rollers and rotating tables. 4. Furnaces
